How to Repair Windshield Scratches

This post is designed to show you how to repair windshield scratches so I’ve whipped up this quick DIY windshield scratch removal guide.

In most instances, the vehicle owner can remove small scratches themselves. With that said, large or deep scratches should be handled by a professional in order to make sure that no further damage is incurred. But if your windshield has a few small scratches, then you can definitely repair them on your own. In fact, repairing windshield scratches should be done immediately.

Here are the steps that you should follow in order to get rid of those pesky scratches. Once you have completed these minor repairs, make sure that you keep a keen eye on the area to make sure that it doesn’t lead to additional damage.

What you Need:

  • Glass Repair Kit
  • Running Compound (must contain Cerium Oxide)
  • Glass Cleaner
  • Dry, Soft Cloth

Note: Always read the instructions included with your glass repair kit before use. This is just a general guide that addresses all of the steps however some repair kits may vary slightly.


Step 1: Diagnose the Scratch

There are two types of scratches: surface scratches and deep scratches. Run your finger over it to determine which type you are dealing with. A surface scratch will feel smooth to the touch. However, you will be able to feel a deep scratch. In other words, if the scratch catches your fingernail then it’s a deep scratch. A glass scratch repair kit is not going to fix a deep scratch.

Step 2: Wash the Windshield

Use soap and water to thoroughly clean the windshield. Once you have finished cleaning it, be sure to wash away all of the soap and then dry the windshield. If possible, let the vehicle sit in the sun for 30 minutes so that there is no moisture on the windshield.

Step 3: Apply the Compound

Double check so that you’re absolutely sure the windshield is completely dry. Then apply the compound to the scratch. The compound squeezes out of the tube like toothpaste and it’s very easy to apply. Rub it into the scratch.

Once you have covered the scratch with compound, spray a tiny bit of water on the compound and then rub it gently. Don’t apply too much pressure. The chemicals in the compound should seal the scratch to prevent further damage.

Step 4: Let the Compound Dry

Once you have applied the compound, let it dry. The instructions should tell you the exact amount of time required. In most cases, it takes 30 minutes for it to completely dry, weather permitting.

Once the compound is dry, wash the window with glass cleaner. It should smooth out.

The goal of repairing windshield scratches is to make sure that the damage does not spread. You might have to reapply the compound every three months in order to make sure that it stays fixed. Pay attention to the scratch. If it turns into a deep scratch, then you will need to take your vehicle to a professional.
