Re: Cleaning Soldering Tips?
I leave an iron on 8 hours a day for my job, so I really gotta keep it clean all the time.
The normal course of action used to be to have a damp sponge nearby to wipe the tip on when the iron is hot - fully up to temperature. It gets all the gunk off pretty well. If the tip is really bad, you can dunk it for a second in a tin of paste flux (for electronic soldering, not the acid kind for plumbing) then wipe it down on the sponge. The flux will emit a lot of smoke so be ready for it and pull the iron out quickly. Should come out glistening.
When you get it shiny, put a little bit of solder on it and keep it on. It prevents the iron on the tip from burning off too quickly.
The best thing I've currently found is a soldering iron cleaner made by Xytronics. It looks like a steel wool pad in a benchtop holder, but the shavings are brass. Poke the iron in it a few times while it is hot, and it cleans the gunk off off better than the damp sponge. It also doesn't cool the iron down, like the sponge, and doesn't start any corrosion either between the heating element and the tip.
If you want to solder a lot, a small investment in a temperature regulated soldering station (Like a Weller 51 series) will make your life much easier. They heat up in 20 seconds or so, and never get too hot. They transfer heat on demand by sensing the tip temperature, so you can solder quicker and more consistently. The tips last a long time, too.
