Fixing a yellowed clear coat (like varnish or polyurethane) on cabinets depends on whether the yellowing is surface-level grime or the result of a chemical reaction.

This process involves lightly sanding the damaged area, removing the old clear coat, and spraying a fresh layer. However, this only works when the base paint is still intact. If the clear coat has peeled completely or if the paint underneath is damaged, repainting the panel is the only effective solution.

Is WD-40 safe for the clear coat? Yes, it won't strip the clear coat, but it can leave residues that dull the finish.
Unfortunately, there's no way to restore a clear coat once it has begun peeling. You'll need to have an auto body shop strip and repaint your car.
