I have a question, did the search thang and couldn't really find an answer.
I have just gotten into getting old and/or antique fire extinguishers and refabbing them. I am having some issues though. I use Brasso and the extinguishers are coming out well, but there are always some spots that need that extra oompf to remove some buildup (blackness, tight corners, imperfections, etc)
Is there any other type of mixture or compound I can use to cut through the crap? Thanks for any help.
