Plexiglass Scratch Removal

Plexiglass is commonly used in place of real glass when an application calls for greater durability and protection from accidental breakage. Small scratches are common in this material, however, and are often quite noticeable. But a quick and easy fix is to rub whitening toothpaste into the scratch. The fine grains of the toothpaste fill the scratch and then dry nearly clear. This takes only minutes, and makes the scratch practically invisible.

  1. Squeeze a small amount of toothpaste onto your finger. Depending on the total length of the scratch or size of groups of scratches, use between a 1/4-inch and 1-inch line of paste.

  2. Smear the toothpaste around the scratch in a circular pattern. Continue rubbing the material into and over the scratch for about a minute to ensure good coverage and to fill all parts of the scratch.

  3. Spray the area with a few squirts of liquid glass cleaner or a diluted vinegar and water solution to help liquefy the rapidly drying toothpaste.

  4. Wipe the toothpaste from the surface with a clean, dry cloth. Wipe across the scratch, not in the same direction as the scratch, to avoid pulling the toothpaste out of the depression. Examine the scratch; if it has gone then the work is complete.

  5. Repeat the process if the scratch is still partially visible or small sections remain. Continue applying and removing until satisfied with the results.


  • Don't use a sponge or heavy-duty cleaning spray or it will remove the toothpaste from the scratch.
  • Only use whitening toothpaste. Don't use a brand with added flavor crystals; they can create more scratches while rubbing.
