Good thinkin' BIZ, that is, trying solvents on that crud I
pulled out. I can fish around in the jacket and can't feel
any thing any more.
I've used phosphoric acid for stripping rusty parts. Behr
concrete cleaner used to contain Phosphoric Acid but they
changed the formula and took out the acid. I was having a
hard time finding anything with a high concentration of
Phosphoric in it till I ran across some Sterosol Milkstone
remover at a farm store. 75% solution. That would clear out
the rust once the greasy stuff was clear.
