  1. 1

    Carefully clean the widow surface using glass cleaner, paying particular attention to the area in and around the scratched surface.

  2. 2

    If the scratch appears relatively light, attempt to buff out using a compound mixture of three parts toothpaste (containing baking soda) and one part powdered baking soda. Mix the compound well before applying to scratch area.

  3. 3

    Apply the toothpaste and baking soda compound to the scratch area by hand. Gently rub in using a circular motion. Allow compound to set for 3 to 4 minutes before using a terry towel to buff the scratch area. Buff using a circular motion while applying moderate pressure. Continue to buff for 20 minutes, or until the scratch is gone.

  4. 4

    Rinse compound from window, and clean with alcohol glass cleaner. If the scratch is partially removed, repeat the process.

  1. 1

    Mix a compound containing equal parts of the following three ingredients: Jeweller's Buffing Rouge (see Resources), green or blue antifreeze containing glycol, water. Mix thoroughly until a thick paste is formed.

  2. 2

    Apply compound paste to scratched area. Allow to dry 3 to 4 minutes.

  3. 3

    Buff with a terry towel using moderate pressure and a circular motion for 20 to 30 minutes, or until scratch is removed.

  4. 4

    Rinse compound from window using soap and water. If scratch remains or is only partially eliminated, repeat this process.

Tips and warnings

  • Do not allow paste compounds to dry excessively as these contain buffing abrasives.
  • Buffing of the compound may be performed using a soft buffing cloth wheel attached to a hand drill.
  • The second compound calls for the use of glycol antifreeze. Anti-freeze is poisonous. When rinsing, be careful in your choice of run-off area.
