It's fun to take the X-Fire to the car wash, (though not at this temperature), but I've never been able to completely clean up the rims, in particular the front rims. Just wanted to check to see if everyone elses' front wheels have this break dust on them. I think the only way to completely clean them is to just a washcloth and scrub, since the wheel degreaser at the car wash only partially works. Any suggestions?
