Let's start with this first: What wheel cleaner did you use and exactly how did you use it? You can get fairly aggressive with the painted wheels on the Crossfire (NON SRT6 I'm talking about here - those wheels are different) but you always want to work on just one wheel at a time. Meguiar's All Wheel Cleaner should do a decent job, but letting it dwell for a minute or so and then hitting it with a mild brush should help, and a clay bar ought to get rid of anything else.

Brake dust that is allowed to bond to the surface and then mix with water and heat can etch into the paint on the wheels so it's really best to clean them often, and thoroughly.

Let me know what you used and we can take it from there.
