So, Joe got a bee in his bonnet a few days ago and decided to clean the rims on the Suburban. They were BLACK with road dust and it was not just going to wipe off. In fact, it wouldn't come off even with soap and water.
So Joe made a trip to the auto supply store and came home with a concoction that he mixed up, and voila! After a lot of elbow grease, here is the result. VERY NICE!
