How to Tin Even the Grungiest Soldering Iron.
Intro: How to Tin Even the Grungiest Soldering Iron.
Let's say you've been a bad maker and let your soldering iron tip get to the point where it's hopeless trying to tin it. Now you can rejuvenate that crusty old tip using a remarkable new technique that's been around for centuries.
STEP 1: What You Need Is...
Some Sal Ammoniac, now I know that that sounds like the name of a Borscht Belt comedian , but it's actually Ammonium Chloride. And it's sold in blocks at places that sell stained glass supplies and occasionally Ace.
STEP 2: Here's What You Do
Heat up the iron, nice and hot, hotter, your getting there, no, hotter, okay Now start rubbing the tip on the the block of Sal Ammoniac, gently now, back and forth, back and forth, round and round and round again. Bored? Too bad. Actually it only takes about 20 seconds. Now the iron will start decomposing the Sal and giving off clouds of HCl and ammonia smoke, try not to breathe it, it's probably not good for you. At this point, you have made a little hole in the block, and you want to feed in a little solder, keep rubbing it around and the tip will be re-tinned. TA-DA!

HCL is a gas, and is most definitely poisonous. HCL alone is not hydrochloric acid. Hydrocholic acid is the aqueous solution of HCL (or if you prefer, HCL dissolved in water).
When HCL is inhaled it dissolves in the moisture on the mucosal membranes and anywhere else there is moisture, whereupon the moisture becomes hydrochloric acid. Much of the damage occurs before even reaching the lungs where, of course, it does even more damage.
Poisons do NOT have to be ingested. If you were right then Sarin gas is not poisonous, nor is snake venom, nor any of a myriad of other poisons just because they're not eaten.

Yep. This works wonders, but do it in a well ventilated area, preferably with a fan to dissipate the smoke. HCL is toxic to your mucous membranes...but probably will not kill you in small amounts.

It can be easily done with soldering paste and solder.
Just clean old solder while the iron is hot or file it cold if too dirty.
Then while it is cold, dip it in paste and turn it on. Keep deeping it in the paste while heating so that it doesn't become in contact to oxygen. Don't let it run dry. Keep trying to melt the solder on the paste wet tip as you must tin it before it becomes too hot that it burns out the paste. I've successfully retinned several very bad irons like this. The trick is: never allow the hot tip to get dry and in contact with air. Oxides will form and prevent solder to stick to the tip.

If you eventually grind or sand through the plating, the tip degenerates very quickly. Looking at the tip in the picture makes me wonder whether this has already occurred.
Radio Shack and others sell little tins of "tip tinner" that is used in about the same technique as the instructable. Smells nasty while using. Several instructions (in various readings) caution users to wipe the tip off throughly with water / sponge, instead of the growingly popular brass "scrubbies".

Old tiymer way is to use an tin can bottom heat the iron up then rub it around the bottom of the can while applying solder to the iron
