I have a few hundred 45 ACP cases, sized and deprimed, sitting in lemon juice concentrate. They have been in the drawer for two years "corroding". When "clean", I'll rinse, wash in Dawn, rinse, and dry.
What polish is recommended? I have tumblers with dry media and polish, but I resisted that route in the first place as I don't want the hassle of punching media out of the primer holes.
