Cleaning old brake dust off trim rings?
The autoparts stores sell all kinds of products (O'Reilly's in my case), I had a set of rims that I tried anything I could find at home (soap, simple green, lacquer thinner, carb cleaner, chrome polish, etc. etc.), and could not get that pesky brake dust off. Tried this stuff and it worked on my chrome rims (Eagle One - Chrome Wheel Cleaner). Mind you these were chrome rims, which are slick, but even with that I could not get them to clean up. Not until I used this tuff which worked great, so I think a product like this or similar may do the trick for you.
