Hi, I own a 2001 VW Passat with Alloy wheels. I didnt wash my car for a few months which caused the rear wheels to have this black dust on them, that will not come off with soap and a regular wheel brush. I tried an SOS Pad on a small remote spot. It worked but scratched the spot. Is there another brush or pad that is effective in removing the black crud but will not scratch the wheels?
thanks,
thanks,
