OT: removing spun bearing material from crank

HemiEd said

Wow, I would have never thought of using a chemical to do that. Interesting approach, very interesting. I will be watching this thread. :read:

I hope it works out for you. I would have been trying to pick it off, and using abrasives.

I have used acid to eat the aluminum that gets stuck in a steel lined barrel when a two cycle piston got too hot and siezed , leaving aluminum embedded in the steel. Had to remove it before honing the cylinder for re-use. Just cannot remember what I used. Might have been muriatic acid.
