Introduction: Clean Green

About: I am a paper engineer, writer, maker and chemist wannabe. In addition to pop-up cards I design and build furniture, lights, costumes or whatever I happen to need at the time. Lipstick, a mixing studio, all-pur…
Making your own cleaning supplies is very easy, quick, cheap, and green. You will be reusing spray bottles which would have gone to waste, you will be reducing your carbon footprint by avoiding transporting water, and you will avoid polluting streams and lakes with phosphates, and the air of your house with strong, unpleasant fragrance and pernicious chemicals.

One of those chemicals is called 2 butoxyethanol, which is present in most commercial cleaning products, in quantities too small to be listed on the labels. However even at those concentrations it has been shown to be absorbed easily through the skin both from contact and vapors. It is carcinogenic, it affects the kidneys and reproductive health (and if female reproductive health isn't visual enough think "testicular atrophy"). Have I convinced you? DIY!

Some people swear by using a solution of 50/50 water and vinegar for just about everything. Not only am I not too fond of the smell, but I don't think it works very well either. I tested various recipes I found on the web and finally came up with my own. The first one is great at dissolving grease and is perfectly safe to use on food preparation surfaces: the alcohol evaporates and the only other inedible ingredient it contains is soap, but there is so little of it the spray can be used without the need to rinse. The second can be used to clean your oven (without killing your braincells or endangering your unborn child) AND your toilet. I like using the glass cleaner for ceramic sinks as well as glass and mirrors. The dishwasher detergent can also be used as a scrubbing powder with bleaching power (and without the harmful vapors). Finally the spray for your shower curtains can double as a fruit and vegetable cleaner.

I mentioned this is cheap and it is: however buying all the ingredients the first time you make these will cost more than a single spray bottle of all purpose cleaner. This will be a considerable long term savings, as you can make many many batches with your supplies.

One last word of caution: always label the bottles properly and include a list of the ingredients. These are perfectly safe to use as directed, and they're definitely less toxic than most commercial cleaners but in case of accidental ingestion you still need to be able to tell the poison control center what the product contains. It's a lot easier to check the bottle rather than look up this instructable while your kid is vomiting and 911 is on the line....

Step 1: Spray for Food Preparation Surfaces

DIY cleaners (or their commercial green counterparts) have the reputation of not working as well as the hard core heavy duty eco-unfriendly brands. I would say this recipe works better than the Seventh Generation brand but it does require a bit (just a tiny bit) more scrubbing than Fantastic.


  • 2 tbsp liquid castille soap
  • 2 tsp washing soda
  • 1 tsp citric acid

Optional ingredients:

  • 1/4 tsp citrus essential oil (orange is my favorite, but any citrus will do -- but sometimes oils react with the soap and don't smell as good as they should).
  • 1 drop (or one gell) of soy lecithin
  • You can also replace the citric acid with 1 1/2 cup distilled vinegar.

One empty, clean, 32 oz spray bottle with the label removed.


  • Mix liquid soap and washing soda in 2 cups of warm water.
  • In separate bowl, dissolve citric acid in 2 cups of water (or add 1/2 cup water to your distilled vinegar).
  • Slowly pour the citric acid (or vinegar) into the soap and washing soda solution, while stirring with a spoon.
  • Pour all ingredients into an empty 32 oz spray bottle. Once things have settled down (it tends to foam as you pour it in), add enough cold tap water to top off your spray bottle. You're done.

Shake the bottle before each use, spray the surface generously and allow it to sit for a few minutes before wiping it off. Most dried-out, encrusted food spill will come right off without any effort.

For problem spots like red wine stains on white formica surfaces, mix together 1 part citric acid with 2 parts baking soda. Sprinkle over the stain, mist with this cleaner (or even plain water) till the powder fizzes, let sit a few minutes and scrub it off.

Notes on ingredients:
I prefer citric acid rather than vinegar because it has no smell and has the same effect: it treats the water, enhancing the performance of the soap and preventing white mineral deposits and streaks. Citric acid is a bit harder to find: in Brooklyn Sahadi's carries it but they call it lemon salt. Kosher grocery stores call it sour salt. But getting it in the spice section of a grocery store is pricy in the long run: you're much better off getting citric acid online, in bulk. It will last for years and you can use it for making bath bombs and lots of other fun stuff, and it will end up being cheaper than using vinegar.

The purpose of the lecithin is to disperse the essential oil in the water -- but is also enhances the performance of the cleaner. Don't ask me why, I don't know. But I tried it with and without, and including lecithin made the cleaner perform better. Plus it makes my Paperstone counters feel silky smooth.

Use liquid castille soap (such as Dr. Bronner's, available at Trader Joe's or at the Vitamin Shop) rather than regular liquid dishwashing soap if you're interested in avoiding the chemicals I mentioned in the intro. Another option is to grate two tablespoons worth of soap off a bar such as Ivory and dissolve it in boiling water.

Washing soda is sodium carbonate, which is more alkaline than sodium bicarbonate (aka baking soda). Including it makes the spray more alkaline, which improves its cleaning potential (more of the splatters in kitchen are acidic -- tomatoes, wine, etc). In NYC washing soda in in the laundry aisle of practically any supermarket. I've heard it can also be found in pool supply stores, sold as "soda ash."

Step 2: Oven and Toilet Cleaner (yup, Both!)

5 teaspoons borax
2/3 cup white (distilled) vinegar or 4 teaspoons citric acid
3 tablespoons liquid castille soap

Baking soda

Clean 32oz spray bottle

Dissolve borax in one cup very hot water. Add vinegar or citric acid and liquid castille soap. Pour into spray bottle and fill to the top with water.

To clean the oven, spray generously all over your oven then sprinkle liberally with baking soda. Spray a little more liquid over the soda and mix together to make a paste covering all the surfaces. Leave overnight, then scrub off and clean with warm soapy water. This DOES require more elbow grease than commercial oven cleaners, but breathing in the fumes will not cause birth defects.

For toilets or any other (non food preparation, non porous) surface, spray and wipe clean with a rag or paper towel.

Notes on ingredients:
Borax can be found in most supermarkets with the laundry detergents (usually on the top shelf...). The most common brand is 20 Mule Team (or something to that effect). It is cheap, and you can do all sorts of fun things with it like making crystals, goo glue or taxidermy.
For citric acid and castille soap, see previous step.

Step 3: Window Cleaner

I've tested many combinations and ratios of ingredients to come up with the one which feels and cleans the best (since I hate cleaning windows this was the only way to motivate myself to get the job done).

1 tsp borax
2 cups water
1 tsp liquid castille soap
1/4 cup rubbing alcohol
1/4 cup ammonia
1/2 cup white (distilled) vinegar

Dissolve borax in one cup hot water. Add remaining cup of cold water, combine all other ingredients and pour into clean 32oz spray bottle.

To use, spray window and clean with crumpled newspaper

Notes on ingredients
I used 70% rubbing alcohol (which is the most commonly available) but of course 91% would work fine too.
Some people might object to ammonia, so let me say this in its defense: it won't be absorbed through your skin or give you cancer 10 years down the road. Its foul smell is an excellent protection: you (or your kids) won't be tempted to breath it in or drink it, and you will be naturally inclined to limit contact and use good ventilation. It's the chemicals which DON'T smell which you need to watch out for!
For borax, see step 2
For liquid castille soap see step 1

Step 4: Shower Curtain Maintenance

Use this spray after every shower and it will help prevent the build-up of white mineral marks on your shower curtain -- and incidentally, this contains exactly the same ingredients as expensive "green" vegetable cleaners, so make an extra bottle and put it by your kitchen sink.

4 teaspoons citric acid
1 teaspoon liquid castille soap
distilled water

Dissolve citric acid in 1 cup of warm (distilled) water. Add liquid castille soap, pour into clean 32 oz spray bottle, and fill bottle to the top with cold (distilled) water.

For shower: Soak your shower curtain after each use. This helps maintain the shower curtain, but it doesn't mean you'll never have to clean it again (as you can see from the picture, it has been many months since I've bothered take my shower curtain down for a good scrubbing).

For the kitchen: soak the fruit or vegetable and scrub if off with a clean rag, brush, or paper towel.

See step 1 for notes on ingredients.

Hope you enjoyed these recipes. They are all a result of my research on an ambitious book I'm working on, called Make Anything: a handbook for saving money, living green and having fun with trash
