Cleaning rims with a gloss coat?
 

One of my co-workers has a set of rims with a non-clear coat gloss white rims. He needs to clean the stuck on black brake dust residue and oxidation & I'm clueless on what to use....

I don't have any experience with cleaning a non-clear coat rim...Can someone help me out?

What's the rim made out of

no idea...
they're rims off a Audi, and the guy he bought them from said its just a plain white gloss paint. I'm assuming its rattle can.

I would try simple green.

I would try the Simple green and light agitation with a brush. If that does not work, a product I have used on ANY wheels (cast aluminum, clear coated, chromed hub caps) with great success is the Eagle One Aluminum Mag Cleaner (I believe it has a disclaimer not to use it on clear coated or painted wheels, but it's worked GREAT in the past for me). I quit using it as my regular product as Simple Green is more environmentally friendly and just a less harsh of a chemical. BUT, in those situations when all else fails, I brake out the Eagle One cleaner.
FYI - If you go with the Eagle One, it MUST be the Aluminum Mag cleaner (I've used the other Eagle One cleaners, not nearly as effective).

Siple green will clean em, i used it to clean my calipers when i just had spray paint on em
