For deeper scratches, your finger will go into the scratch and this requires a more specialized windshield scratch repair.

You may be lucky enough to remove minor scratches with a glass polishing compound but if not, you will require a complete glass polish kit. This kit will contain all of the items that you will need to accomplish your scratch removal process.

In order to remove scratches from your windshield, follow the below steps.

Clean The Windshield

Wash the windshield as thoroughly as you can before doing anything else. You will want to use an auto glass cleaner to thoroughly clean the glass. You don’t want to put the glass polishing compound on the windshield with dirt on it.

Once you have used the cleaner, make sure to rinse any residue left on the glass. You want to be sure that once you add the compound to the windshield, you don’t have any dirt trapped underneath it.

Adding The Glass Polishing Compound

Once the windshield is clean and dry, you can then add the compound to it. The compound should look like toothpaste and be easy to rub into the scratch. After applying the compound, you will need to spray it with water and rub the it gently with a soft cloth. Try not to apply too much pressure as you do this, otherwise, you may push the compound back out of the scratch in the glass.

After you have successfully applied the compound to your windshield and the scratch, you will then need to let it dry. Make sure to follow the instructions on the package to help you understand just how long you need to let it dry.

Once, it has completely dried, you will then need to wash the windshield and dry it with a car drying towel.

Once you have completed this process, you should have a scratch-free windshield. If the scratches remain, you can attempt to reapply the glass polishing compound but it may be that the scratch is too deep to repair.

Level of Abrasive Qualities

When researching through the different types of glass polish products, you will want to check the strength of the formula. Some may only be suitable for water spots and light scratches, which won’t be ideal for those tackling deep scratches to their windshield.
