Just curious, Mr Gorsky, if you've tried the muratic acid mix on anything that has electrical connections on it?
I'm thinking about the steel turn signal housings for example...mainly the soldered wire ends in bulb sockets. Think the acid would leave the solder alone? Still fooling with it, but tried the cider vinegar bit on them (lol, 2 days), and after looking fairly good. After, a water dip, tossed into my kerosene tank, pulled to dry, and watched rust coating again.
Prob right now, is it seems still some rust behind the socket 'plastic' spring-loaded contact plate. Messing with it, but won't push in far enough to get a bulb into the socket.
I've dealt with muratic acid plenty of times in the past, usually stronger than your mix. Know it doesn't hurt plastic, or the like, but not sure on solder, copper, brass, etc. (Used to clean my engine blocks with a 50/50 mix, for the water jackets.)
Any ideas?
Solder is 60% tin and 40% lead. Both of these metals react with diluted hydrochloric acid, but very slowly. I've had some solder in the mix for an hour now with no obvious effect. Doesn't react with copper, but will with brass....so you can use it to clean up brass.
I've got similar issues with my bulb sockets, but I've got them all working at the moment. When the time comes, I'll replace them with $3 items from RockAuto...check them out.
