I'm a proud owner of a 2008 Z06 with chrome wheels. Does anyone have advice on getting the grease and brake dust imbedded on the inside of the wheels? Not the chrome portion, but the wheels themselves. Needless to say, the inside of the rim is difficult to reach, so all suggestions are welcome. I'm also not thrilled about what lookes like rust on the inside of the brake rotor, but I'm guessing that is a common complaint. If there is a relatively in-expensive fix for the rust, here in Orange County, CA, I'd truly appreciate being pointed in the right direction. The car is still under warranty, although I'm assumming this is not a warranty issue. Thank you in advance, Robb in the OC.
