How To Remove Scratches From Windshield?

ByTsukasa Azuma-December 10, 2023

What could be the most unsightly thing and potentially dangerous too in a beautiful car? Well, nothing could beat scratches on the windshield or windows! A graze on the body paint comes closer, but it in no way causes an accident. How to remove scratches from windshield? Can you even fix this problem or have to change the glass?

What Can Cause Scratches from Windshield

There are several daily items that might harm a car’s windshield.

Wiper blades that aren’t working

The surface of the wiper blades on the windshield can harden with age and neglect, producing scratches, especially when the glass is dry. The same thing can happen if a little item, such as a pebble, becomes stuck between the blades.

Inadequate cleaning

Scratches might occur on your windshield if you wipe it with a rough/dirty cloth. The easiest technique to clean safely and properly is to use a soft microfiber or cotton cloth.

Debris on the road

Scratches are also produced by rocks and pebbles flying into your windshield from the road, particularly while driving behind vehicles and lorries, which readily trap rocks on the road.

Ice scrapers that have been damaged

If you live in a cold, snowy climate, you may need to clear ice from your car’s windshield and glass on occasion. Ice scrapers are designed to protect the windshield, but if they become worn or broken, they can harm it.

How To Remove Scratches From Windshield?

A scuff or cut on the windshield obstructs the sight of vision at the time of driving. Also, even a hairline crack can turn into a full-blown laceration over time. Once that happens, you have no other way except for replacing the windscreen, which is expensive.

What to do? You can just fix the chip or crack so it does not get bigger. Remember that it’s not possible to repair a deep graze, anything deeper than 50 microns. 

How do you know that it’s technically fixable? If the crack catches your fingernail, it’s too deep to be repaired at home. If that’s not the case, follow these methods:

For Light Scratches

Using an acrylic scratch remover to fill in a light scuff or crack is the easiest answer to your problem of how to remove scratches from windshield

You have to apply this liquid to the affected areas and rub with a wet microfiber cloth or a super fine sandpaper (600-grit or more). It will look transparent when dry hard and conceal the damage with a protective layer.

But, this chemical is not available at many local stores. In that case, you can use a glass scrub product (such as Glass Science Glass Scrub). 

It is mainly used for erasing persistent stains and grime. However, it also works just fine for fixing light cracks on the windscreen.

Wrap your hand in a damp microfiber towel, pour some liquid on it, and rub the damaged area. Work on a small section (if the crack is a big one) at a time and maintain even pressure throughout. 

It’s an abrasive ingredient that will cut through the surface in case of direct application.

For Deep Scratches

Cerium oxide is a great solution for fixing deep scratches. These are still less than 50 microns but deeper than just a light graze on the surface. 

The chemical ingredient is mainly used in ceramics and jewelry industries for its low-abrasive nature. It’s good for polishing metal, ceramic, and glass items.

Add water to the powdered cerium oxide to make a paste with semi-liquid consistency. Apply it to the scratched area. A hand drill with an attached hard rubber polishing wheel will come handy in this case. 

Use it to polish the area where cerium oxide is used. The whole process needs patience and consistent application of the paste and polishing. 

Be careful about the consistency of the mixture and the amount of the pressure applied by the drill. The reward will be a clean, scratch-free windscreen that provides a clear vision while driving.

Isn’t it better to take the car to professional for the deep scratches as there is a big chance people can make mistakes? Or people can do it on their own?

Hi Jack Says I’ve got exactly the same problem. Brand new Skoda Kodiaq and an arc shaped scratch on driver’s side. I used quixx acrylic scratch remover (made for plastic not glass) but It didn’t work. So probably the only solution is to polish it with cerium oxide. I’ve owned Ford S-Max for a couple of years and no scratch problem at all. There must be some flaw in VW glass…

Hi my car is brand new and the other day I noticed that there was a large scratch on my front windscreen (drivers side) which is in the shape of an arc. To be precise it runs the full sweep of the wiper end (tip of the blade) and is only very fine but still noticeable in certain light/directions of viewing. Is it possible to polish it out to make it less noticeable? and what would be the method and product to use?
Thanks in advance for any advice!

This article saved me a lot of money 🙂 Thanks for sharing it. I am not sure if this scratch remover can be found in Bulgaria but I will check up .
And remember if the damage is larger, it would be better to replace the windscreen.
