hydrogen peroxide

I am wanting to make some sulphuric acid because it is on of the most useful acids around and i have ran into a problem. after you burn sulphur to create sulphur dioxide you then need a catalyst to form sulphur trioxide and then dissolve in water. which catalysts could be used and could you just let the sulphur dioxide dissolve in hydrogen peroxide (so2-----so3------h20--------h2so4 or so2 ------ h202---------h2so4).if this would work how could you get a large enough concentration of hydrogen peroxide?

H202 production

Wondering if any one have come across a video showing the steps or know how to do this and how to extract H2O2 form the solution to make hydrogen peroxide like discribed from wikipedia article http://en.wikipedia.org/wiki/Hydrogen_peroxide#Manufacture i know i just cut and pasted to make it easer the history  barium peroxide with nitric acid. An improved version of this process used hydrochloric acid, followed by sulfuric acid to precipitate the barium sulfate byproduct.  Sodium peroxide also makes H2O2 Na2O2 + 2 H2O → 2 NaOH + H2O2 those are hard to come by for DIY and thought maybe this would easier  inorganic processes were used, employing the electrolysis of an aqueous solution of sulfuric acid or acidic ammonium bisulfate (NH4HSO4), followed by hydrolysis of the peroxodisulfate ((SO4)2)2− that is formed. peroxodisulfate commonly referred to as the persulfate ion hydrolysis is a chemical reaction during which molecules of water (H2O) are split into hydrogen cations (H+) (conventionally referred to as protons) and hydroxide anions (OH−) in the process of a chemical mechanism.[1][2] It is the type of reaction that is used to break down certain polymers, especially those made by step-growth polymerization. Such polymer degradation is usually catalysed by either acid, e.g., concentrated sulfuric acid (H2SO4), or alkali, e.g., sodium hydroxide (NaOH) attack, often increasing with their strength or pH.>

Copper chloride without H2O2-adding?

Hi! I think i will see some PCB-Etchin in the future... So i will need an etchant. Aequous copper chloride was the choice i made since it is a regenerative etchant according to several sources. Now if i understood the chemistry right (Sorry... electrotechnician here), the reaction in theory only needs the oxygen from the peroxide (H2O2) and the hydrogen isnt used at all? Since i only have relatively weak peroxide, i plan on using a bubbler to introduce the oxygen to the copper-HCI-mix. This because i dont want to dilute the acid too much... Will that work? I know that if i use normal air (which has only around 20% oxygen in it) it will take some time... But would it work in the first place? I read somewhere that copper and muriatic acid dont really react in the first place... So if i also understood that right, it needs the oxygen present in the beginning to START reacting... So i think i may go with a contraption like: Plastic container with a bubbler installed (Pumps normal air) Add Muriatic acid to the container Add copper to the acid let it bubble till the copper is disolved Now i have a copper chloride-solution which i can regenerate by adding oxygen (By bubbler or H2O2)?

Hydrogen Peroxide at home and in the Garden

Although the topic is quite old for some of us and mostly because I am too lazy today to make an Instructable: Hydrogen Peroxide ! Back in the day Hydrogen Peroxide was mainly known for the ability to bleech your hair, later it replaced chlorine based products for the preparation of paper and organic fibres. For me it is a good opportunity to go back in time and to pull out some of the remedies my grandparents already used. Who knows, there might be something that helps you or you might know other good uses that I failed to mention here, so feel free to comment. First off: What actually is hydrogen peroxide? We could check Wikipedia but I think it is enough to say that it basically water with an added oxgen mulecule which turn the stuff into a quite powerfull oxidizer. When hydrogen peroxide reacts the added oxygen is released and the normal water remains. Precausions and health risks. In the normal supermarket form hydrogen peroxide comes at a strenght of just 3%. This is just enough for wound treatment or cleaning off a fresh and small stain. The stuff you can buy at your hair dresser comes in concentrations of 5-15%, above that it is of little use to them. Pool grade peroxide however can come as high as 50%. It often requires a permit of at least leaving a copy of your drivers license to buy such high concentration but well worth it price wise. The downside of anything above 5% is a risk for your skin, eyes and airways. So when handling hydrogen peroxide you should waer long sleeve rubber gloves, safety or better swimming goggles and make sure that you don't create vapour by spraying it against the wind direction. Having water at hand to dilute and spillage on your skin is always good. What happens to me if things go wrong? Well, if handled correctly nothing should go wrong but of cause the worst would be eye contact. Getting concentrated hydrogen peroxide in your eyes means extreme pain and even with rinsing it out asap eye damage is more than just possible. Again: wear proper eye protection and if spraying use a filter mask, the paper type is enough!!! Nothing immediate happens on sking contact but a few minutes after contact the skin will turn slightly brown or goes white. This is caused by the oxygen release into your skin cells, if washed off quickly after noticing the discoloration will fade after a few hours. Prolonged exposure of the skin can cause skin cells to fully discolor and living cells might get damaged - a burning sensation is usually the sign that you need to wash the area now ;) Enough bad stuff said, let's see what we can do in the garden.... Fungal infection of your old roses or on your fruit trees? Sometimes the weather does not like our plants and by the time we discover a fungal infestation it is usually pruning time. There are commercial producta available that work quite well but especially the copper based ones tend to do more harm than good in th long run. An alternative is a solution of 10-20% hydrogen peroxide. Spray generously over all affected parts of the plant, leaves, twigs, stem and all. Make sure everything is properly wet! In some cases the fungus can act as a water replellent and it seems impossible to get any of the solution to wet these areas - a drop of dish washing liquid into the bottle will fix this! Watever runs off can be left as it only helps to get oxygen into the soil but of course you should not soak the area... Leave it on for about an hour, around 20 minutes if it quite warm. Rinse all off with clear water and repeat every 2 days for 5 treatments all up. After this time wait 2 or 3 weeks and check if the fungus still gows in some hard to reach areas. If so then repeat the treatment there until satisfied but wait another 2 weeks every 5 single treatments. In some areas of the world certain types of fungus on roses are refered to as "rust". ----- Moved into a new home and the garden beds smell really bad? The last house I moved into had a previous occupant with a big dog but no time to clean after his pet. The garden beds looked dead and I mean so dead that I could not even find weeds in them. And the smell was a distinct mix of old dog poo with lots of fresh cat poo mixed in it - the perfect outdoor pet toilet :( Trying to dig it all under made me recover that the top soil was more §$&*# than soil. I had to get rid of the bacteria of all the poo and somehow neutralize a lot of the unwanted "nutrients". The solution was to first loosen all the soil as deep as I could go. Then I added rice straw (but anything straw like or dry grass will do) to mix it through. At this stage I wished I had a gas mask LOL All up the contaminated garden beds covered about 20square meters. I got a 10 liter canister of pool grade hydrogen peroxide, from this I diluted down with 20 liters of water and a few drops of dishwashing liquid to help with the soil wetting. All was applied as evenly as I good with a watering can and then the area was covered with some tarp to try keeping as much oxygen on and in the soil as possible. A day later the tarp was removed and all beds watered with hose to drowning point. This watering was repeated every 3 days for 3 weeks to drive out all the excess and unwanted nutrients from the poo. The smell was already gone except for some cat urine residue which disappeared after some rounds of watering. Three months after the initial treatment I did some soil tests, added nutrients were required and the next season I had vegetables growing :) ----- Planting? Whether from seeds or seedlings, give hydrogen peroxide a try! I use a 5% solution to soak the potting mix I use before putting my seeds in it. Not only does it kill a few of the unwanted things that might still be in there but it adds a lot of oxygen into the soil, which gives the seeds a much better start. For seeds I use a 5% solution as well but only leave them in for about an hour before placing them between some wet paper towels until they start germinating. This way I can be sure all harmful bacteria and fungal spores are dead and I can use a sterile seed to keep going. Might just be my opinion but I think the germination rate is better and seedling in comparison start growing faster and stronger. Home uses.... As we learned before hydrogen peroxide, at least in higher concentrations is a powerful way to remove fungus. In our bathrooms we often have the problem that the ceiling starts to develop black spots as in the colder times water condenses here and takes a long time to dry off. If you now go to your favorite hardware store they will recommend the use of a chlorine based product, basically bleach... And although it does the job it also means your house will stink for days and if you scrub the ceiling you will get it on your sking and stink too. Hydrogen peroxide at 20% or higher concentrations can be sprayed onto the cleiling :) Of course you will need good protection for this and all things color should be removed, like towels or floor mats. By protection I mean a minimum of swimming goggles, a tyvek suit or similar to cover all exposed skin areas and at least a paper dust mask, better a filtered respirator like you use for spray painting or using insecticides. If you have a spray bottle with an adjustable nozzle then a stream is far better than a spray mist!! Not only is your exposure far lower but it much easier to wet the ceiling quickly. Wet all affected areas, then leave and the room, close the door and take off all clothes you used t protect you. The clothes can be left out to dry but double check that you had no soaked spot where your sking might have been in contact - if so rinse the skin with plenty of water! It will take some time to work and then dry, so best to do this in the summer time or if during the colder times you need to make sure the room is porperly heated and aired out to dry! Repeat until all black spots are gone, really bad areas will leave a permanent discoloration looking like a slight brwonish color is the ligh it right otherwise you won't see it. Once fully dry it is best to scrape off all lose paint and then to use a acrylic based sealer before giving the ceiling a fresh coat of white. The sealer will prevent the water to penetrate more than the paint level and if you get the fungus back on the paint it is far easier to clean ;) ----- Carpet cleaning.... When moving into a new rental with carpet on the floor you often are left with areas indicating the carpet might be "clean" but the underlay certainly is not. You can fix the underlay but you certainly can make sure all harmful stuff is gone from the carpet. Carpet cleaning machines can be hired but often much cheaper if you buy the "recommended" cleaning product with it. Rent is usually based on a daily base and price depends on how much cleaner you need. If you only want to desinfect the carpet which otherwise looks mostly fine than go for the smallest pack available and use it to spot clean areas you want cleaner first. For the desinfecting part I recommend to test how high you can go with the concentration of the hydrogen peroxide before using it on a big scale - keep in mind the carpet will never be fully dry and the remaining peroxide will continue to act! Test a 10% solution first before you go higher as you don't want to buy 30 liters or more of pool grade peroxide - just trust me on that one and only try to buy this much you do want to get into trouble a few days later! If 10 percent solution left on the carpet does not cause any bleaching of the fabric (unwanted bleaching that is) you can try higher for spot cleaning in demanding areas. A good spot to try the solution is under the cover or duct outlets, under these joining bars where carpet changes to tiles (if you can lift them off) or in wardrobes if the carpet goes inside. There are two way to treat your carpet once the general cleaning is done. a) use a garden sprayer or similar to wet the carpet This is good for single room treatment like for the baby room but especially on thicker carpets it requires a lot of solution and can become costly. Once wet leave for at least 30 minutes so the peroxide can do its thing, then use the machine with either the solution filled or just to dry off the carpet. I recommend to use the peroxide solution in the machine as it allows for better penetration and it will remove more soiled solution this way. If your catching container starts bubbling like mad it means you have a lot of §$%&#+ in the carpet and it might be best to first clean it all with the normal carpet cleaning agent before using the peroxide again - again tesing on smaller areas can help wasting the peroxide. If you need to store prepared solutions than it is best in a cold place. It will take several hours on an otherwise clean carpet for the peroxide to fully disappear so it best to use shoes and prevent skin contact during that time - especially if a baby crawls around ;) ----- Toilet.... We don't want to talk about it but everyone needs to clean their toilet sooner or later. For most things in there using the toilet brush when it happens will keep things clean and healthy. But what if someone in the house is sick or with a weak immune system? You could use all sorts of commercial cleaners and desinfectants but a wipe with wet towel or cloth soaked in a 10% solution of hydrogen peroxide will quickly eliminate all harmfull things on your seat, lid or bowl, including the buttons to press and the door handles ;) Just wipe and leave it wet for a minute or two then wipe again and ry - done! Personal use I always pack a small bottle of supermarket grade peroxide when going off road or camping trips. Although we now have modern desinfectants that won't stink or otherwise harm you I still prefer the old stuff ;) If you are far from civilisation than the last thing you want to need is medical attention for something that started as small as a scratch or graze.... Out in the unkown wilderness you will never know if the rockk you just crash landed on was used as a urinal by a fox the night before... A bit of gravel left in your skin might contain harmful bacteria... A cut with your own knife?? - What did you all cut since the last proper cleaning of the blade? You see where I am going here, a small thing might turn into something really nasty a day or two later. If you clean a freash and minor wound properly and then rinsie it with hydrogen perodixe most if not all harmful leftovers will be killed by the releasing oxygen. Of course this pretty much useless on bleeding wounds or where it is obvious that you won't be able to remove all debris from the wound - here it means you trip is still over in favour for proper medical treatment. The thing is that hydrogen peroxide was basically abandoned for all wound treatment once the modern "cleaning aids" became available as the peroxide will not only attack harmful things but also living tissue. The claims goes as far as causing bad scar tissue, damage to blood vessels and even "burning" of the tissue. One big problem I have with all these claims is that they were never really mentioned until the new meds came out. IMHO exposure time and how you use it it the key - common sense if you ask me. Noone should ever soak a wound in peroxide, if it is that big that you need to soak it you need medical attention anyway. And as said you should rinse the wound, that means all remaining liquid should be allowed to flow off - this will only leave a minor amount of peroxide in the wound and the exposure time will end with once all oxygen is released. For minor wounds I only use a paper tissue or cotton bud soaked in peroxide and wipe the wound.... ----- Smelly feet? Ok, maybe not the best way to start a conversation but we all know what sneakers do to our feet in the summer... Insoles with copper and activated carbon will help a lot and at least "cure" your sneakers while they are off your feet and have time to dry. But the smell is actually cause by bacteria growing from everywherey in your sneaker to your sking, actuall starting at your sking... If you wear your sneakers for long periods of time time or even whenever possible and also suffer from a bad smell hydrogen peroxide might be able to help you. Most sneakers will tolerate a machine wash and should come out germ free, if that is no option pack them in a sealed back and leaven them in the freezer over night - this will kill all bacteria and remove the smell. Now to break the endless cycle you need to remove the bacteria from inside your skin. So daily sock changes, freezing shoes and washing feet is a must! Your feet will really benefit from a foot bath in a 5% solution of hydrogen peroxide. To keep costs at a minimum use a container that is just the right size for your feet and prepare the solution from pool grade peroxide. I an ideal case you should not need more than 2 liters but all used product can be stored cool and re-used the next day, after that you need to make a new batch. Keep your feet submerged for at least 10 minutes. This will allow a deep penetration of the skin but might result in some white spots that will disappear after a few hours. Consenquent foot baths can be reduced to 5 minutes. After about a week you should notice that wearing your sneakes no longer causes and bad smell and you can stop the treatment. Freezing the sneakers over night, dialy (or more) sock changes and daily, proper cleaning of your feet should prevent any further bad smells :) ----- Bleaching your hair Althoug it was done for many years I really can't recommend using hydron peroxide for this purpose! Any concentration strong enough to have a proper effect in a reasonable time will at least cuase skin irritation. Back in the days they said your burning scalp is what you need to endure to get blonde hair :( And as said already you really don't want to get that stuff into your eyes... General uses If you have a fruit based stain then cahnces are hydrogen peroxide will remove it, especially if fresh. Even at supermarket concentration repeated application and proper drying off with a paper towel or similar will remove even red wine or beetroot stains. ------ Blood... On you skin blood is easy removed with cold water, same on other surfaces but washing off is no option a wet cloth or cotton piece will work fine. Hydrogen peroxide is good if things need to go fst or if the surface is porous, here the releasing oxigen will drive out the blood with the bubbles. ----- Fish tanks... If you love your tank then you really hate to medicate or even worse have a bad algea infestion, especially the stuff of the black kind. A change to activated carbon filter material is always recommended after a medical treatment to remove all leftovers from the system. However, certain medication simply won't be affected by a carbon filter and stay in the system until fully used or broken down otherwise. Especially in bigger tanks a partial water change is often out of the question as it would cause too much additional stress to the fish and plants. Hydrogen peroxide can help to break down most if not all remains of the used medication while at the same time adding more oxygen to the water. To be sensitive and safe in all enviroments I recomment to calculate the concentration based on the volume of your tank and to add the required amount of peroxide very slowly into the outgoing water stream from your pump. By slowly I mean in terms of a slow drip if using solutions over 10% to be added to the tank. If in doubt remove a suitable amount of tank water into a bucket and add the concentrated peroxide to reach the final tank limit. I strongly recommend to stay below 2% in favour over additional treatments a few days later if required. That means the diluted solution you add should be entered into the tank slowly if in doubt add a glass full every few minutes. For the treatment of the dreaded black algea you do the same 2% solution but be prepared that it will take several treatment until you see them die off. If you can then it is best relocate the fish for a few days so you can use a stronger solution of 5-8% just with the plants left in the tank. When transporting fish in a bag it can pay off to add a little bit of 3% peroxide to the bag to give additional oxygen for transport. I do this maually for every fish I buy from a store so I can be sure all fungus and bacteris is killed of before I introduce it to my tank. Really helps to prevent loosing a lot of fish just because you added one or two more to your tank ;) For the normal sized transport bags I use a good shot glass full of 3% peroxide in case you wondered. ----- Fridge and freezer Be it after long use or because you bought one second hand - once empty and warm some of our colling gadget just smell bad. A good clean with a hot water and your favourite cleaning agent is a good start, no need for aggressive stuff ;) If clean but still smelly, like after a power failure with fish in it you might want to go one step further. Best option is to use a spray bottle and a peroxide solution of at least 15% here. Use proper protection as mentioned above and spray all surface with the solution until soaked. What you can take out you take you take out, clean properly and then wipe or brush with the same peroxide solution. Bare aluminium should be handled with caution as in some cases it can oxidise badly, leaving a white and not removable crust behind. Here it is best to wipe and then wipe again with a cloth soaked in clear water to limit exposure time. No need to dry out - wipe out and check if it still smells, if so repeat and wiped off all areas as good as you can with a solution soaked cloth. Once the smell is gone dry out and enjoy smell free use from now on :) ----- Fruit and vegetables Unless you know exactly what happened to it you might want to clean your vegies and fruits properly before using them. Pesticides, herbicites, fungicites.... Not mention normal fungus and bacteria on the product.... On a commercial base hydron peroxide baths are often used to clean products for sensible people, hospital use or long term storage. For a personal use this only makes sense if you have free and unlimited access to the peroxide. An alternative are ozone bubblers. Expensive models can eb bought in shops or online, complete with timers or even a gauge showing the concentration in a room. On a hobby level for the kitchen sink we can use an ozone generator, air pump and bubble stone from the aquarium store ;) Let the pump bubble out the ozone for a minute or two, fill the sink with the fruit and veggies and move them around every few minutes. Best of course with an open window to limit you exposure to the ozone! Rule of thumb: If you can smell it is already too much in the air! The ozone in the water does the same as the peroxide: It breaks down harmful things with pure oxygen. The downside is that it is very harmful for your airways and body in general, so against all what youtube can offer I actually prefer to treat my fruit and veggie in a sealed bag. Place them inside, push out as much air as you can and then fill up with the ozone from the generator. Once the bag is full leave for about 30 minutes then wash and use or place the things in the fridge.

I gave her peroxide and she threw up about 30 shards.  they were sharp enough to remove a sliver from your finger.  Never give you dog pork bones, EVER.  I don't know everywhere they are sold but I got mine at TSC  My dog is fine by the way.

Safe DIY PCB etchant

Hello out there, I was wondering if anyone knew a safe, homemade PCB etchant other than the vinegar and hydrogen peroxide method. That produces copper (II) acetate and I don't have any use for it other than copper plating, and I suck at electroplating anyways. I would like to find a safe, homemade copper etchant that is easily disposed or can be reused for something.  Thanks, Sam.

Sodium Chlorate production other ways?

Sodium chlorate production without the need of keeping the solution at around 50-70°C from  the electrical power used for electrolysis?  sodium chlorate production besides having to heat from amperage the sodium chloride solution and electrolysis then would a catalysis to help with oxygenating the solution like instead of water use 3% hydrogen peroxide or manganese dioxide or ever ammonium nitrate and yield sodium chlorate using electralysis with out needing to keep the solution at 50-70°C?

Anyone know of a persulfate-free method to dye brown hair blonde?

I'm allergic to persulfates, which are the chemicals in hair dye that strip the hair of its natural color.  I found this out after I had my hair professionally dyed, broke out, and went to the dermatologist.  I know that peroxide can also lighten hair, but I was hoping someone had good techniques or experiences with that or a similar persulfate-free lightening method.  My hair is very short so I'm not worried about breakage.  Normally I would just let something like this go, but as it turns out, I look really good as a blonde ;)

The more natural way of cleaning things...

At my workplace we basically have a specific cleaner or cleaning product for every task you can think of. From glass over stainless to plastics and desinfectants for lots of different surfaces. After a quick look into my cleaining cabinet at home I started to wonder if I am doing something wrong as I only have a few cleaning things for my use. Asking my friends also showed they have a big bunch of cleaning chemicals, plus the bottle of bleach that everyone down here has. So I though: Your grandma only had a few cleaning products and you learned most of things you need to clean from her. Considering I grew up healthy I guess she must have done something right.... Let's clean up with the cleaning myths, shall we? 1. What cleaning chemicals do you have? For quite a few people the list would start something like this: Dishwashing liquid, window, cleaner, bathroom cleaner, soap scum remover, floor cleaner, oven cleaner, several desinfectants.... If that is true for you too than we might be on to something already. 2. What cleaning chemicals do I really need? This is a good question as everyone is a bit different but I assume a healthy household here. Of course we need certain things to clean our various surfaces properly but it is far less than waht you have been told by the TV commercials.... These days we like to think if there is a special cleaner for something then of course we have to use it to clean properly. Unless you have trades people walking through with their wet dogs several times a day and see dust storms at least twice a week you really only need a few things. So let's get to the basics: 3. Old style cleaning and what you need for it - really the only stuff required to keep all clean and sanitised. a) Methylated spirit b) Clear ammonia - cloudy ammonia works too but be aware that the added soap can be a problem that leaves streakes c) Hydrogen peroxide - pool grade to be cheap in the long run d) Orange oil - citrus oil works great too if you prefer a different smell e) Soap - just basic soap, these stinky, slightly yellow and hard bricks - no fancy smelly soap ;) f) Several cleaning brushes but you should already have those g) Windows cleaning tools - the basic microfibre cloth and squeegee will do h) Several microfibre cloths - bigger ones for floors and walls, smaller for windows and the rest I) Yesterdays newspaper j) Baking soda With those few things we have everything to clean whatever comes up and if bought in bulk comes down to a few cents per bottle compared to a few dollars when you buy all the stuff you don't need. Lets figure out what the stuff does and how to use it: 4. Mixing and what to use it for.... The alcohol is a really good remover for everything greasy and also desinfects the surfaces. A quick spray and wipe on your bench is all that you need to remove oily residue or the mess from the kids. Mixed with a bit of soap and water (about 50-50) also removes sticky stuff like jam or syrup. If we use about 50ml of alcohol, 50ml of clear ammonia and 900ml of water we get one liter of really good window cleaner. The modern way is to use microfibre for the cleaning and a squeegee to get it dry, the old way just uses a cloth and then the window is "polished" with some old newspaper. The black ink reacts with the alcohol and form a mild abrasive while the paper soaks up the moisture, the result is a prefectly clean window in under 3 minutes. Orange oil is not only a powerful degreaser but also lifts old dirt or even glue residue. Used directly it will get rid of the remains from sticky tape, stickers and everything that other cleaners fails to get off - smoth surface and non soaking of course. 50ml of it with 50ml of ammonia and 100ml of alcohol per bucket makes a good florr cleaner and your house smells nice when done. Works best if you can use a microfibre cloth or floor wiper to dry the surface with it. In the kitchen we can find a lot of surfaces that are greasy and we already covered that bit, so lets get to the though stuff. The kitchen sink can become dull looking although it is not scratched. This is due to hard water, food residue, soap and other things. Best is of course to wipe it and dry it after use but who really does this every day? A pot scrubbing pad with some baking soda on it does the trick here. Make the pad nly moist and sprinkle the baking soda on it. Rub over the stainless and if too dry add a few drops of water. Once done rinse off and enjoy the difference. For hard to clean or badly turtured sinks you can try a ball of aluminium foil and coke - use it like a polish. The oven is often our worst nightmare. The cooktop is not far behind. But even here we can have a chance to clean without too much hard work or bad chemicals. Of course the best way is to prevent these spills and boil overs ;) For the cooktop some hot water and baking soda will soften the baked on stuff. Simply remove what you can with the hot water and then sprinkle the surface with baking soda. Cover all with the paper towels and if not wet enough add a bit more hot water so all shets are soaked. Leave ove night and wipe clean the next day. The oven is a bit of a problem once the side and back wall are filthy. If baking soda with a pot scrubber won't do the trick get some of these steel pads with soap in it. The soap in them is special in terms that you only need a little bit of water to remove almost anything with them - and they won't scrath enamelled surfaces. On the bottom we often have badly burnt in things that are next to impossible to fully remove. I suggest to cover the same way as the cooktop but also to add some orange oil. Just make a thick paste of baking soda and orange oil and wrok it into the soiled surface. Cover with wet paper towels and leave over night. Now you don't want to flood your oven, so that means you need to use a sponge or thick cloth that is big enough to wipe off the surfaces you soaked the day before. As the orange oil really is oil it pays off to use some alcohol in the cleaning water to get rid of the oil and grease a bit easier. Don't expect to see a clean and shiny surface after one treatment if the oven was badly misused, you might have to repeat the procedure a few times. If in doubt use the soapy steel pads for last clean and before soaking over night again. Three to four treatments are usually enough to clean even the worst disaster that can happen in an oven unless you baked it in for months... 5. Desinfecting and mouldy spots.... As said, the methylated spirit is basically just pure alcohol and kill almost anything that might harm you. But sometimes that just is not enough. And who really wants to spend an hour or longer to clean some mouldy spots in the shower or try to cover the smell by spraying room freshener? As a lst resort for everything I use Hydrogen Peroxide. The supermarket grade is only 3% and usually badly overpriced, so I suggest to get a small canister of pool grade peroxide. Do yourself a favour and ask them to install a tap on it - you don't want to do it yourself unless you already know how bad pool grade peroxide is! For your own safety when handling it I strongly recommend wearing long rubber gloves, nitrile is better but please no latex as it could start to burn when getting in contact with the peroxide. For high grade desinfecting or the removal of mouldy areas I recommend to dilute 1:5, one part of peroxide to 5 parts of water. Only for the mould removal on tiled, plastic, glass or metal surfaces you can use the peroxide pure from the container - but please add face protection when cleaning! Some spray bottles work with peroxide some just start leaking badly, if you want try an old bottle of chlorine based cleaner after really flushing everything out. The peroxide breaks down any organic material it comes into contact with, so not just the mould you want to remove but also your skin or eyes if you allow contact. On the skin you see white areas after contact and they won't go away until all the oxygen in the skin is gone that was left by the peroxide. If you act too late it means you might loose some skin flakes. The sure sign of overlook exposure on your skin is a burning sensation in the area - this only happens when the amount was big enough or your clothes got soaked. On your surfaces to clean you will notice bubbles forming quite quickly - this mean the peroxide is reacting with something, usually organic material. Let it bubble... Once it stops bubbling the surface is either sterile or the peroxide is used up, if it bubbles when adding fresh peroxide onto it then there is still crap left ;) It really helps to brush off the surface after each treatment as a lot of loose material will be flushed out when rinsing off. Once it looks and smells clean again it usually means it is clean :) 6. Special case: Wood... Be it wooden floorboards, furniture or just your chopping board - always try what the manufacturer recommends first! Untreated wood should never be cleaned with anything wet! Sealed wood, like floorboards or things with varnish on it to make it water proof can be cleaned the same way as mentioned above - but I would leave out the ammonia as some wood treatments simply won't tolerate it and might go dull instead of returning nice and shiny - spot testing required if you think you have to use ammonia as well! Orange oil itself makes a great furniture cleaner if the surface is smooth and sealed, but if it is not it means the oil soaks into the wood together with the stuff you want to clean off! It also takes off several paints and types of varnish if you work it hard enough and give it some time, so avoid this and be quick instead of forgetting to finnish the job ;) Always try to wet the surface as little as possible and wipe fully dry as soon as possible! Ok, good start but what is the real benefit? For me the actual benefit is that I know what I am using and exposing myself to. Just reading what is in most cleaning products we find at the supermarket makes me want to clean again after using them, just to remove their residues... I admit it might take some time to get used to mixing and just having a few ingredients for the cleaning but it does work great. Especially if you or your kids are already sensitive to certain chemicals or just of poor health in general you might see the benefit quite quickly. Some people really don't like the smell of ammonia but unless you are sensitive to it there is nothing to worry when using the household grade as we always dilute it down massively anyway. A good way to avoid the worst stink is by mixing it outside with the wind from behind. I won't say that certain commercial products are bad, harmful or not good enough for the job. Some are actually worth to have in some cases but I just say it is better to only have a hand full of chemicals that are not too bad instead of an endless list of things were we don't even know what's inside. For me the best is your surprise when it actually works better than you expected and report your findings here.

Peroxode or Boil this Mummy?

Hi, I found a mummified small animal (possum, little dog, raccoon) under a friend's house, when doing plumbing repairs. It is all there except maybe the feet. I cant really tell, because he is kinda twisted around, and I have not touched him yet. There is some skin, no fur - he is so dry that the live animals arent even iterested in smelling him. I would like to clean and maybe try to articulate him; if too many bones are missing I will just keep his skull. My question is - what is the best way to remove the dry skin? Instructions I have read are all about fresh skin. Should I boil him or just soak him in peroxide to remove his skin? Thank you!

PCB etching left over paper

Hey everyone! I'm in the process of etching my first PCB. I have a few questions. I'm using the toner transfer method, with hydrochloric acid and a little hydrogen peroxide as an etchant. Anyway, I transferred the toner to the board, but I believe the glossy paper I used may have been a little too thick. The toner transferred correctly, but i can manage to get all of the paper off. I've tried a tooth brush and a soft towel. My question is, if I just go forth and etch the board will the paper dissolve with the copper on the board and give me a clean result anyway? Will the copper covered by the paper not be removed? are there any cons to this? (such as not being able to reuse my etchant) Thank you all, your help is appreciated Ken
