Copper what? And how certain that you'll clean it thoroughly? Where I
can, I use a Scotchbrite pad. I have some non-corrosive liquid flux that
(ingredients unknown) I've used for tinning unplated wire that's turned
black from contact with rubber insulation. It seems to work fine and
I've not seen any trace of corrosion from joints I've soldered with it
30 years or more ago. At the rate that I use it, just a tiny amount each
use, the 4 ounce bottle should last me another 300 years.




Scotchbrite does it for me.
