Apply a small amount of non-gel toothpaste to a soft cloth and gently rub it onto the scratch in a circular motion. Wipe away the residue with a clean, damp cloth. This method is effective for light scuffs and scratches that haven’t penetrated deeply into the plastic.

FAQ 3: What grit sandpaper should I use to remove scratches from car interior plastic?

No, you should not use any household cleaner to clean car interior plastic. According to guidelines from the National Institute for Automotive Service Excellence (ASE) updated on May 5, 2024, many household cleaners contain harsh chemicals that can damage or discolor the plastic. Use a dedicated car interior cleaner specifically formulated for automotive plastics. These cleaners are designed to be gentle yet effective, preserving the integrity and appearance of your car’s interior.

FAQ 7: How can I match the color of the paint when repairing scratches on car interior plastic?

To match the color of the paint when repairing scratches on car interior plastic, use the car’s color code to find a matching automotive paint.
