Remove Oxidation and Fading From Your Hard Tonneau Cover

Although your hard tonneau cover may look dull and worn, you can restore its original luster by effectively removing oxidation and fading.

Start by using a fine-grade rubbing compound or an oxidation remover specifically designed for automotive plastics or vinyl. Apply it with a soft cloth or foam applicator in small, circular motions, working gently to avoid damage. Focus on areas with visible chalky residue or discoloration.

Removing oxidation revives the cover’s appearance and prepares it perfectly for the next restoration step.

After treating the entire surface, wipe off any excess product with a clean microfiber towel. Don’t rush—patience guarantees you remove the oxidized layer thoroughly. If needed, repeat the process until the surface appears more vibrant.
