Windshield wipers, ice scrapers, dirt and other abrasives can scratch windshield glass, causing a windshield to appear dingy. Deep scratches can ruin the appearance of the car and may not be completely removable. However, deep scratches can be blended to appear less visible. Surface scratches are less noticeable than deep scratches, and can be buffed out until the windshield is restored to its original condition.

  1. 1

    Place masking tape around the scratched section of the glass. The tape will allow you to know exactly how big the scratch is, and focus on the area of the windshield you need to repair.

  2. 2

    Rub a jeweller's rouge lightly over the scratch. While you are applying the jeweller's rouge, rub a lamb's wool buffing pad in circular motions over the scratch. Use the least abrasive grade of jeweller's rouge, to prevent causing more scratches.

  3. 3

    Continue rubbing the jeweller's rouge and lamb's wool buffing pad over the scratch, until the scratch is gone.

  4. 4

    Mix 4 tbsp of ammonia and 1 gallon of water in a bucket.

  5. 5

    Dip a sponge into the bucket, and wipe the sponge over the windshield. The solution will rinse off the residue from the jeweller's rouge.

Tips and warnings

  • Extremely deep scratches may need to be repaired by a professional windshield repair company.
