Removing battery acid in aluminum

**No Butt No Putt** · 05-02-2014, 12:35 PM

I picked up this billet battery tray that had blue powder coat on it. I removed the powder coat with aircraft paint remover, but it has some battery acid build up on it. Does anyone know how to remove it? It appears to be on top of the polish and not eating away or into the aluminum. Any help would be great. Thanks guys.

Get it damp and sprinkle baking soda on it and smear it around and let it set for a few minutes. This will neutralize the acid. Then you can do what ever you like to it. Polish back, paint, powder coat, what ever. But you need to neutralize the acid first.

After it's neutralized I can just polish over the corroded parts? It will polish back out?

That's probably going to require more than just hitting it once with mothers.

I have a polishing wheel and compounds.

Just hit it on the wheel, but be careful to "blend it" otherwise you will have a low spot right there. If the wheel isn't cutting it, then it might need to be belt sanded and re done.
