This is an aggressive pre-cleaner designed to remove all traces of wax, grease, silicone, oil, road tar, adhesive and other contaminants from the vehicle before sanding or other prep work begins. Wax & Grease Remover should never be used on paint that has already been sanded, fiberglass, plastic or anything previously painted with lacquer.
After thoroughly cleaning the surface with water and detergent, towel dry, then apply Wax & Grease Remover to one section at a time. Wipe onto the surface using a clean rag, then wipe off using a different clean dry rag before solvent evaporates. If pre-cleaner flashes dry before it can be removed, re-wet the panel and continue. Use separate rags to apply and remove to prevent the transfer of contaminants from one panel to the next.
