What could be the most unsightly and potentially dangerous thing in a beautiful car? Well, nothing beats scratches on the windshield or windows! A scratch on the body paint comes close, but it certainly doesn’t cause an accident. How to remove windshield scratches? Can you even fix this problem or do you have to change the glass?
What can cause windshield scratches
Several everyday objects can damage a car’s windshield.
Faulty windshield wiper blades
The surface of windshield wiper blades can harden with age and neglect, producing scratches, especially when the glass is dry. The same can happen if a small object, like a pebble, gets stuck between the blades.
Improper cleaning
Scratches can appear on your windshield if you wipe it with a rough/dirty cloth. The simplest technique for proper and safe cleaning is to use a soft microfiber or cotton cloth.
Road debris
Scratches are also produced by pebbles and stones thrown onto your windshield from the road, especially when driving behind vehicles and trucks, which easily trap road pebbles.
Damaged ice scrapers
If you live in a cold, snowy climate, you may sometimes need to remove ice from your car’s windshield and windows. Ice scrapers are designed to protect the windshield, but if they wear out or break, they can damage it.
How to remove windshield scratches?
A scratch or chip on the windshield obstructs vision while driving. Furthermore, even a hairline crack can turn into a real laceration over time. Once that happens, you have no other option but to replace the windshield, which is expensive.
What to do? You can simply repair the chip or crack so it doesn’t get bigger. Remember that it is not possible to repair a deep scratch, one deeper than 50 microns.
How do you know it’s technically repairable? If the crack catches your fingernail, it’s too deep to be repaired at home. If not, follow these methods:
For light scratches
Using an acrylic scratch remover to fill a light scratch or crack is the simplest answer to your windshield scratch removal problem.
You need to apply this liquid to the affected areas and rub with a damp microfiber cloth or super fine sandpaper (600 grit or higher). It will appear transparent once dry and conceal the damage with a protective layer.
But this chemical is not available in many local stores. In this case, you can use a glass scrub product (such as Glass Science Glass Scrub).
It is mainly used to remove stubborn stains and grime. However, it also works very well for repairing light cracks on the windshield.
Wrap your hand in a damp microfiber towel, pour a little liquid on it, and rub the damaged area. Work on a small section (if the crack is large) at a time and maintain even pressure throughout.
It is an abrasive ingredient that will go through the surface if applied directly.
For deep scratches
Cerium oxide is an excellent solution for repairing deep scratches. These are still less than 50 microns but deeper than a simple surface scratch.
The chemical ingredient is mainly used in the ceramics and jewelry industries due to its low abrasiveness. It’s good for polishing metal, ceramic, and glass objects.
Add water to the powdered cerium oxide to get a semi-liquid paste. Apply it to the scratched area. A hand drill with a hard rubber polishing wheel attached will be useful in this case.
Use it to polish the area where the cerium oxide is used. The entire process requires patience and consistent application of the paste and polishing.
Pay attention to the consistency of the mixture and the amount of pressure applied by the drill. The reward will be a clean, scratch-free windshield that provides clear vision while driving.
How to prevent windshield scratches
Regular cleaning and maintenance
- Clean it regularly using a soft microfiber cloth and a mild glass cleaner.
- Remove stubborn dirt and bugs with a mixture of water and mild soap.

Proper wiper blade maintenance

Parking considerations

Using windshield protection films
- Clear adhesive films can provide an extra layer of protection against debris.
- These films are almost invisible and can be easily replaced if damaged.
Avoiding abrasive cleaning materials
- Use only microfiber cloths and mild cleaners.
- Avoid using abrasive sponges or towels that could scratch the glass.

FAQ on how to remove windshield scratches

To remove scratches from your windshield, do not use toothpaste. It is intended for teeth, not glass, and can worsen scratches.
