FYI - I spoke to the detailers at my dealer and they let me in on their secret... apparently they don't use rim cleaner on new rims (no need) .... once you have them clean, get some VARSOL... its a weak solvent that you can buy at any hardware store... take a cotton cloth and dab it in the Varsol and use it to cover the entire rim... once the solvent has evaporated a thin film of oily residue will be left on the rim... this creates a barrier and that brake dust will not be able to bond to the surface of the rims... you'll notice that you will be able to wash the brake dust off with a gentle spray of water... you should clean your rims as usual, and use the VARSOL.. becareful not to get any of the Varsol on your brake calipers or discs...
