How to remove scratches from a windshield (easy ways)

Car windshield scratches are most often the result of the inept scraping of windows in the winter and contact of the glass with sand and all kinds of dirt from the road. Prolonged use of worn wiper blades further exacerbates the effect.

Stones falling from under the wheels of other cars, sand scattered in winter, scraping ice, or untimely replacement of windshield wipers are the main causes of car windshield imperfections. Unfortunately, this happens even to those drivers who are very careful about the cleanliness of their cars.

If damage occurs on the side or rear windshield, this is not such a big problem. Unfortunately, it is the front windshield that is most often scratched, which not only affects the overall aesthetics of the car but in some situations can also cause light refraction. A scratched windshield can make it difficult to see during your drive.

scratches from a windshield

How is a car windshield made? What is it?

Three layers of laminated glass make up a windshield. Between two sheets of glass, there is a layer of vinyl.

These layers are subsequently fused under intense pressure and heat in an autoclave, a special furnace designed for creating windscreens.

As a result of the windshield’s laminated glass construction, it offers a safe driving environment by guarding against inclement weather, injuries, and accidents.

The windscreen has three layers, thus only the outer layer may be damaged; this is especially true when there is only a low to moderate impact and only tiny scratches. It is crucial to remember that you don’t have to choose to replace your windscreen entirely to correct these marks.

Determine if it’s a scratched or a cracked car windshield

The scratches and cracks are distinct from one another. They are brought on by many mechanisms and need various forms of repair. The difference is that cracks reduce the strength of the windshield, but minor scratches don’t.

The main source of scratches is lateral forces, or an abrasive object moving sideways. The abrasive material could be a tiny grain of sand, a very tough insect exoskeleton, or a carelessly chosen washcloth.

The agent either leaves some of itself behind or scoops a small quantity of windshield glass while traveling sideways.

Although heat or pressure can also produce cracks in the windshield, the impact is the most common cause of them. The energy from the impact is absorbed through cracking in the most common scenario where a piece of debris strikes the windshield.

Driving visibility may be negatively impacted by cracked windshield cracks.

You may quickly tell whether you have a scratch or a crack by using the “fingernail test.” Run the tips of your fingernails over the affected area with a hand that is not wearing gloves. Your fingernail catching indicates that you most likely have a crack.

Fine scratches shouldn’t go deep enough to grab your fingernail unless they are quite severe.

A cracked windshield needs to be fixed right away, preferably by an expert. Cracks frequently go far deeper than what is evident, and even a tiny crack can seriously impair your car windshield.

Estimate the scratches’ depth and severity

Deep scratches vs. light scratches on your car’s windshield.

To find out if you can fix a scratch on your own, apply the fingernail test. Probably requires expert care if the scratch is deep enough to grab your fingernail.

Deep scratches might require professional intervention, possibly even a replacement of the windshield, whereas tiny scratches can be repaired using do-it-yourself techniques.

The best way to determine this is to see the damaged region in full sunshine, which will offer the highest level of contrast and make the car’s windshield scratches more obvious.

What can scratches on your car’s windshield be caused by?

There are numerous commonplace items that can harm a car’s windshield.

Unreliable wiper blades

When the wiper blades on a windshield are old and neglected, their surfaces can harden, which can scratch the glass, especially when it’s dry.

If a little object, such as a stone, is caught between the blades, the same thing may occur.

Ineffective ice scrapers

You might occasionally need to scrape ice off your car’s windows and windshield if you live in a cold, snowy climate. Ice scrapers and other tools like them are designed to protect the windshield, but if they get worn out and broken, they can scratch it.

Incorrect cleaning

Your windshield may occasionally develop scratches if you clean it with a scratchy cloth. The ideal method for careful cleaning is to use a soft microfiber or cotton cloth.

Road rubbish

Rocks and pebbles flying into your glass from the road can also scratch your windshield, especially if you are following a four-wheeler because they can easily trap the rocks on the road.

How to remove scratches on your windshield

You can remove scratches on the windshield of your car in a number of ways. The following are a few of the most common ways to remove scratches from a windshield.

Glass repair kit

Every tool you need to repair scratches comes in a repair kit. To remove scratches, follow the methods listed below.

  1. Your fingernails can be used to measure the depth of the scratches. You can distinguish between surface scratches and deep scratches on the windscreen by rubbing your fingertips over these scuffs.
  2. The glass repair kit can be bought locally or online.
  3. Apply the glass repair kit on the windscreen to begin the repair process. Cerium oxide is present in the cleaning agent. To prevent the scratch from getting worse, it will chemically react with the glass.
  4. 35 to 40 minutes should be given for the compound to dry.
  5. With a soft cotton cloth, clean the impacted area.

Acrylic scratch remover

You can get an acrylic scratch remover at the majority of neighboring stores or online. It is one of the best techniques to get scratches out of automobile windows. The steps for utilizing acrylic scratch remover are listed below.

  1. Apply the acrylic scratch remover to the windscreen with a cotton cloth.
  2. Spend 60 to 70 seconds rubbing the towel over the scratch.
  3. Give it 25 to 30 minutes to rest on the windscreen.
  4. Use a delicate cotton cloth to wipe the glass clean.
  5. Gently remove any remaining scratches.

Toothpaste without gel

Non-gel toothpaste is another common item that is useful for fixing automobile glass. In order to restore automobile windshields, non-gel toothpaste serves as a grinding paste. Around the scratch, a very small portion of the glass is removed.

It is possible to completely level the injured region by using non-gel toothpaste. For a thorough description of how to use non-gel toothpaste, read the steps below.

  1. Use a soft, lint-free cloth to dry the glass.
  2. Grab a soft cloth and dab it with non-gel toothpaste.
  3. Apply the toothpaste to the damaged area of the windscreen for 30 to 45 seconds in a circular motion.
  4. A microfiber cloth should be used to wipe the toothpaste, and the affected area of the windshield should be dried with a soft cloth.

Acrylic nail polish

Acrylic nail polish, which is primarily used for cosmetic purposes, can be used as a tool to patch small dings in the windscreen.

It has the ability to harden as it dries thanks to certain qualities. So even the smallest scratches can be effectively repaired. Use transparent nail polish by following these procedures.

  1. Apply the nail polish to the scratch and quickly rub off any excess.
  2. Allow it to dry for a while.

Water pump-equipped buffing machine

Minor scratches can be leveled with a buffing machine and distilled water. Avoid using it to remove deep scratches from four-wheeler glass, as it could permanently damage the windshield. For a more thorough explanation, see the steps below.

  1. Near the windscreen, wrap the car’s body in paper or plastic.
  2. To successfully use water on the windshield, create a dam-like structure out of duct tape. Do it vertically first, then horizontally.
  3. Use the machine to buff the area after pumping the distilled water into it. Continue until the damage is indiscernible.
  4. Use a tiny amount of compound repeatedly.
  5. Repeat it several times daily until the scrape disappears.

Professional support

It is best to get professional assistance if you think the scratch on the four-wheeler glass is too deep or is more of a crack.

The windscreen must be completely replaced if it cracks.

How to polish windshield glass in a few easy steps

The windows should be the final thing you clean and polish when washing your car.

Use an automotive glass scrub compound instead of a regular glass scrub compound because the latter may include ammonia and other chemicals. Instead of using a regular towel, use a microfiber one that may be used to gently moving on the glass without harming it.

Glass scrub compound is normally used to remove tough dirt and filth from glass, but they can also be used to repair tiny surface dings on the car windshield glass. If rubbed on the glass for a very long time, it can be highly abrasive.

Dab some glass scrub compound onto a clean, damp cloth. Apply the compound to the scratch, working in small, circular motions. After a few seconds, spray the scratch with distilled water.

Remember to roll the windows down halfway while using glass cleaner so that you can reach the top edge of the glass.

It’s time to wash the windows right now. Apply the glass cleaner. Wash the windshield with a glass cleaner, then dry it completely. Wipe both sides of the glass with a microfiber cloth. In the conclusion, you can rinse with water.

A glass scrub can be purchased separately online or from a nearby store, or you can purchase a glass repair kit that also includes other supplies.

Use a polisher with a 1,000–1,200 rpm speed (revolutions per minute). Make sure the polishing pad is present.

How to remove deep scratches from car window glass?

While most minor scratches can be removed with the proper tools, deeper scratches should be repaired by a glass repair specialist.

Purchase a glass repair kit, acrylic scratch compound, or glass cleaning compound as described in the sections above.

If necessary, use the water pump technique along with the buffing machine.

Scratch-free windshield

Keeping the wiper fluid reservoir full at all times is one of the simplest ways to guarantee a scratch-free windshield.

Contrary to popular belief, the upkeep of a windshield depends more on the choice of wiper fluid.

Additionally, a bottle of premium wiper fluid costs not much money and wouldn’t affect you in the slightest if you kept it on hand in your garage all year. Make sure your wiper fluid is periodically inspected, preferably once per month, for the cleanliness and health of your wiper blades.


Glass scratches that are particularly deep are generally safe (apart from obstructing your vision, which is dangerous on its own), but in some circumstances, they can weaken the windshield and cause a crack.

Consult experts for scratches that are too large for DIY restoration. Ask a professional to examine your windshield when you go to a garage. They’ll have access to top-notch chemical mixtures that can cover up scratches without leaving a trace.
