Hydrochloric acid and a sand blaster lolOr... what NOT to use?
I thought that you couldn't wax anything that wasn't painted... cause then the metal cannot breathe like it is suppose to. Anyways, I'm going to just wash them with soap & water, use some rim cleaner, and keep my eye out for some "gunmetal polish" - if there is such a thingwax them with car wax
