How to Remove Scratches From a Glass Windshield

Scratches can be removed from glass windshields.

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.

Things You'll Need

• Masking tape
• Jeweler's rouge
• Lamb's wool buffing pad
• 4 tbsp. ammonia
• 1 gallon water
• Bucket
• Sponge

Instructions

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

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

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

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

Tips & Warnings

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