Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I have been using the same bottle for about 2 years now (give or take a bit). I pour it into an old film developing tray, toss my PCB into it for a couple of minutes, then return the stuff to its original bottle. It certainly has NOT degraded the product's ability to tin a circuit board. As for rinsing, I put it in the sink, and run water on it for about 10 to 20 seconds - cold or warm water, whatever comes out of the faucet.

Yes, the stuff stinks a tiny bit like rotten eggs. Not knowing what this chemical actually is, I usually do it outdoors to be safe.
