Step 1: Tools of the trade

Picture of Tools of the trade
This section will explain the tools of the trade. Some of these you will need, some of these you will not. The first (and most common) apparatus is the simple yellow sponge.

Yellow Sponge
The purpose of the sponge is as follows; the sponge is porous, so it holds water. Rubbing a hot soldering iron tip on a wet sponge causes the solder to contract at a different rate than the soldering iron, helping to knock off any globs of solder that may be clinging to the tip. NOTE: Make sure the sponge is damp (not soaked) with water.

600 Grit Sandpaper
The second tool of the trade, is 600 grit sandpaper. NOTE: Paper ignites at 451 F, so make sure the iron is unplugged, and has had time to cool before using sandpaper. You will only use sandpaper if the tip has been abused by the previous technician, student, or co-worker.

Tip Tinner / Cleaner
You wont need this if you've got some extra solder. I wouldnt recommend spending the money to buy it unless you have a high-end soldering iron ($XXX.XX price range) for all intensive purposes, regular solder will work just as well for what we're doing.

What about its maintenance cost whether it is highly cost or
low cost?

"For all INTENSIVE purposes"? I've never heard of such a thing. Intensive purposes? Is that like the normal saying "for all intents and purposes"?

That's very nice illustration for cleaning and maintenance, after getting these tips think my work would be easier.

Hey! if u have got the spongeBOBs corpse, how can I have one :( !!!

instead of a soldering sponge, use a 'curly' metal tip cleaner
Google "GOOT ST-40"

I am happy to say I have never been given instruction to soldering. Why did my soldering iro tip get a great big chunk eaten out of it after one board. I was told to put solder to tip! What am I doing wrong?
exponent (author)  Jezza Bear8 years ago
Can you upload a picture of the iron somewhere? I've never saw the tip of an iron get eaten away.
OK, here it is. The whole tip has fallen off now, but it had a chunk taken out of the side and it crumpled in
exponent (author)  Jezza Bear8 years ago
Sometimes tips will overheat if the iron left on for long periods of time without soldering. This can cause the metal to loose a bit of its strength. However, I've never seen something this bad before. It almost looks like the tip melted off. I have no idea why this happened. Perhaps the iron is getting too hot because of a design flaw or defect.

Hi, you can actually add a dimmer to the soldering iron to control the heat/power of the soldering iron. For more information, please visit http://www.bustatech.com/adjustable-soldering-iron/ for the story on adding a dimmer to soldering iron.
Thanks for the feedback, it is a cheap iron for me to learn on. I bought one of these children's robots to learn how to solder components and I after one board of about 20 components you could see a hole appear on one side getting bigger and bigger. It has dented my confidence a little, but I shall have another go as it is one of those skills that is needed. Thanks for getting back to me
Mine did this too! I don't solder for electronics, though. I used it to make a bunch of microscope slide pendants, with soldered edges like in stained glass. I assumed the melted iron tip was because I was using lead-free solder, which has a higher melting point, and was really too much for my cheap cheap iron to handle. It's a $7 range iron, so nothing too bad lost.
exponent (author)  BubbleDragon8 years ago
I'm begining to think some of the cheaper irons have an alloy tip that isnt as strong as conventional steel, and thus through processes unknown (possibly galvanic corrosion) the metal weakens.

I managed to find a chart here Galvanic Corrosion Chart that may open some doors to this theory.
Hi,I was wondering what watt your iron is,I got a 100watt from draper-not for electrics as the watt is way too high/15watts+ I think is better for light electric stuff.-but I have had the tip ,what seems like melt on me.I have just written to them to see about returning it and I was wondering if yours was a draper iron too........I will let you know what they recon if they come up with a cause.
Hi Oliver It is a 15 watt one and very cheap. What you pay for is what you get. Maybe I need to get a better one, practice on simple things like joining wires and then move to more complicated scenario's
mine has a chunk taken out too, but i can't figure out how to get that little extra bit of solder out of it
exponent (author)  bigpinecone8 years ago
Theres a good chance that when the tip was cast, a void or air pocket occured in the casting.
This sounds like a plating failure. Too much force applied to the tip will cause the iron plating to crack. Once the copper core is exposed, solder will erode it rather quickly. This hollows out the tip, which then collapses. A sure sign of a stress failure is a hollowed-out or jagged tip. It's easy to think that pushing hard on the iron will increase heat transfer, but it really does more harm than good. The best ways to improve heat transfer are to use the biggest tip you can (to maximize contact area) and use a molten solder "bridge" between the tip and the joint.

I had a little accident with my first solering iron....I just connected it a waited for it to get hot, but at some point it started smoking...when I was going to unplug it, it suddenly began sparkling and finally it lit on fire! Fortunately, it didn't came to worse, but it still frightened me bad. Why did it happen? I checked the iron and saw that the inner cable (which I suppose is what makes the iron get hot) was burned, so my bet is maybe it was touching the metal parts and thus began to melt. Duuhh....how can I prevent this from happening again?
The iron was defective - what you described sounds like an electrical short. I would take the iron back to where I bought it and exchange it. Preferably for another brand.
Actually, the phrase is "for all intents and purposes". Otherwise, good instructable.
Well, Liquid, maybe he/she REALLY likes soldering, to the point that they have a fanatical allegience to a clean tip, then perhaps it could be "intensive" care of an iron.
Yes. Or maybe he just used an incorrect phrase.
I actually thought it was a joke and found it funny.

Or you could use a small brass parts brush like i use

I'm an A/V technician by trade and just thought I'd share a trick I picked up a few years ago. I used to use the old damp sponge method until a co-worker of mine introduced me to the fine-bristle, brass grill-brush. Brass is abrasive enough to remove the gunky buildup, but is a softer metal than the tip itself and so won't damage the underlying protective finish like the sandpaper might if you are too heavy handed with it. As an added benefit is it doesn't cool down my iron like the damp sponge does so I can immediately continue soldering. All it takes are a few light, quick strokes (like buffing shoes) and the tip is clean, shiny, and bright.

You can use ceramic tip.And works very well.No rust!!!!!Less maintenance
pyroman507 years ago
Or right after you solder you could scrape it with a razer blade.
that will work '''UNTIL''' you solder again. see, when an iron is made,at the end of the process it is given special coatings to better protect against extreme heat. these layers are very delicate and using a razor blade would scrape of the layers,giving way to warping.sandpaper*ahem*EXPOENT has the same effect
I had no idea you knew of this! lol

*looks to Liquidhypnotic...* picky, picky, picky. *G*

There will be those that will nit pick everything you say & do in life... best advice for you about them is, ignore it. I don't always know the proper terms for things I do either, but I almost always get the point across. My 2 cents on this Instructable?? I give it 2 thumbs up. when you're trying to help make others lives better, who really give a ragweed about proper terms anywway?

Keep up the good work.

Well that is some good advice, but all that falls by the wayside of the 100% best way to take care of your soldering iron. And it is most simply this: Go buy a box of that bulldog steel wool. Keep it beside your soldering station. Everytime you take the iron out of the receptacle, with a few quick strokes ala knife sharpening, run the steel wool over the tip. There you go. Always perfectly clean, perfectly tinned soldering iron.
exponent (author)  ColeP8 years ago
Steel wool is pretty helpful, but it will never replace the sponge =) Always good to have some steel wool around though because it does a great job at cleaning the iron.

I've had stupendous luck with cardboard, actually. It's abrasive and absorbent enough to rub the crud and oxides right off, but it's soft enough that it doesn't wear down the tip cladding. Try just stabbing the hot iron tip through the side of a corrugated cardboard box a few times, I think you'll be surprised! It's also oddly cathartic. ;)

cool thakns i just cleaned mine and it was free! thanks alot :D
hmm. My Iron is a 30-watt radioshack model, which i just sponge off and after like 15 times of using it i sand down the tip to get everything off, then later mabe buy a new tip for like a doller :-)
tnraven7 years ago
Rosin core solder that builds up over time can actually eat away at the tips. Acids and whatnot form and cook on the surface of the metal. That combined with cooling/heating can cause the metal to become soft..
