After washing your wheels, apply some wax or sealant to the surface. This will protect the painted surface from contaminants and make it easier to clean the next time you have a car wash therapy session. Be sure you use a non-abrasive wax or sealant and that your wheels are painted and or clear coated before you apply a product. Wax is also safe to use on chrome wheels too!
