Pre-wax cleaners prepare the paint surface for wax or sealant application. These cleaners remove contaminants such as old wax, oils, residues, and light oxidation that can interfere with the bonding of the protective wax or sealant. By thoroughly cleansing the paintwork, pre-wax cleaners ensure optimal adhesion and durability of the subsequent wax or sealant. They also enhance the gloss and clarity of the paint, allowing for a more vibrant and reflective finish.
