Chrome oxidizes over time and begins to develop rust spots. The higher quality the chrome is on your chrome wheels, the more it will resist oxidization, but it will rust sooner or later. Oxidized chrome can be handled in one of two ways. The first way is to restore the surface. If the oxidation has caused pitting in the chrome, the piece must be taken to a plating company to be rechromed. In most cases, the first way will apply and the method that is outlined here will do the trick. Wash the chrome finish with soap and water to remove grime and dirt. Remove surface rust with a steel wool pad and a lot of water. Pour household cleaner into a bowl or small bucket and wet the toothbrush in the cleaner. Scrub the oxidized areas to remove the oxidation. Rinse the chrome surface of the wheels. Rinse off all cleaner and soap residue from the surface of the chrome wheel with clean water.
