You should avoid using cleaning substances containing acids because they may discolor Rim Ringz™. For best results, use only the cleaning agents from reputable manufacturers. Those cleaning agents are made for car rims, and they will be perfectly suitable for Rim Ringz™.
When you wash your car, we suggest that you also wash, with water, the area between the rim and Rim Ringz™, so that the small pieces of dirt would get out from this area. That dirt can cause scratching. Rim Ringz™ is not responsible for any damage on your wheels due to this dirt. Even if you wash your car with automatic brushes, Rim Ringz™ will not fall off, as long as it is mounted properly and the tire dimensions are set in accordance with the rim size.
