How to Remove Deep Scratches From Windshield

10 Ways on How to Remove Deep Scratches From Windshield

1. Determine the Depth of Your Windshield Scratches:

First, place a coin flat on the glass. If you can see the top of the coin from above, your windshield scratches are minor. But if you can’t quite make out the lettering on top of the coin, then your windshield scratch depth is about 0.125 inches or more and should be handled by professionals. Make a note of the scratch depth to determine best which solution you will use on your windshield.

2. Prepare Your Auto Glass Repair Kit:

You should have a clear coat or scratch removal kit in your garage that you can use to remove scratches from the windshield. This kit will typically contain a polishing compound, clear coat paint, and an abrasive pad. If you don’t have one, now is the time to go out and purchase one.

3. Polish Away the Scratch:

Apply a small amount of polish to an optional microfiber cloth or foam applicator pad. Then rub small circles over your windshield scratch. You can do this by hand or use a battery-powered drill to speed up the polishing process. Be sure not to press too hard on your windshield, as doing so may damage it further.

4. Buff Away Any Excess Polish Residue:

Use a clean microfiber cloth or sponge to wipe away any excess polish not absorbed into the windshield. This is to prevent any stains or to spot on your window when it dries.

5. Apply Touch-up Paint:

Using a small brush, apply touch-up paint after removing the scratch to your auto glass repair kit. The touch-up paint will not only give your scratched windshield a nice even appearance, but it will also prevent rusting.

6. Clean Up the Scratched Spots:

After the touch-up paint has dried, clean up any excess liquid with water. If there are any excess spots of touch-up paint on your windshield after you’ve wiped them away, use a razor blade to remove them. Just be sure that there is no residual liquid left on your window, or it will leave marks when it dries.

7.Polish Your Windshield With a Power Drill:

You can also use a power drill to remove the scratch. Attach a wire brush bit and buff out scratches by holding the drill perpendicular to your windshield and moving it up and down in small circles around the scratch. Be sure to do this over a newspaper or drop cloth to prevent any additional scratches to your car’s paint job.

8. Wash and Dry:

After you’ve finished polishing your windshield, wash and dry it thoroughly to remove any debris or grit leftover from the process. Once again, be sure not to use anything abrasive such as a paper towel, as this will cause additional scratches.

9. Use the Glass Repair Kit:

If the deep scratches on your windshield are still visible after you’ve polished and dried your window, it may be time to bring in a professional. A glass repair kit can remove most surface scratches from glass; however, deeper ones will require special tools and products.

10. Take It to a Professional:

If you find that the scratch in your windshield is too deep to remove yourself, it’s time to call a professional. A professional will buff out the scratch using a different type of polishing compound. They will also be able to fix any cracks in your windshield.

Some Tips and Suggestions

Here are some tips and suggestions on how to remove deep scratches from windshield.

1. Use a new pencil eraser. In some cases, especially with deeper scratches, this will be the only thing that works to fix your windshield.

2. If you use a cleaner on your windshield already, make sure it has ammonia in it. Ammonia is what works to remove the paint from your car. When the paint is removed, you end up with that transparent look on your car again.  

3. Use wonderful grain sandpaper or a rotary car buffer with a very soft foam pad. Whatever you use, be sure to go in a circular motion with the scratch across your windshield. This will ensure that there is even pressure on the scratch and it may even help get rid of any deep ones by using this method.

4. Using a pencil eraser, rub it on the scratch until you see the greyish-white powder form. Keep rubbing until most of it is gone or not visible. Then use your cleaner with ammonia and wipe away the remaining powder.

5. If you don’t have any pencil erasers available, you can also try using a white eraser in school. It has the same properties as a pencil eraser, but it is a little harder to get working. Be sure to rub very hard on the scratch until there is powder visible and then wipe away with your cleaner containing ammonia.

6. If neither of these things works for you, try using wonderful grain sandpaper (400 grit should work well) to rub down the scratch gently. You may need to use your pencil eraser or white eraser afterward for best results.

7. If none of these things work, try taking your car to a professional detailing shop and ask them if they can buff out the scratches with their machine. They use much more powerful tools so that it may work for you.

How Much Does It Cost to Repair a Scratch on the Windshield

Scratches on the windshield are very common, but people who have them rarely want to live with them for long. The good news is that there are a few simple steps you can take to remove scratches yourself or find out how much it would cost to repair them professionally. If you choose to deal with it yourself, follow these steps:

1. Buy Scratch Remover

There are several scratch removers available in stores, but you should opt for the one that works on glass. Please do not use an abrasive cleaner or an abrasive sponge, as it can worsen the scratches.

2. Test It First

Before applying the scratch remover to your windshield, make sure you test it on a small area of the windshield. This is to see if your windshield can withstand the solution; some newer models may not be able to.

It should not cause damage, but stop immediately and take your car into a service center if you notice any cloudiness or new scratches forming after applying and wiping off the scratch remover.

3. Wash the Windshield Thoroughly

Wash your windshield with dish soap or a mild window cleaner to remove all residue that may prevent the scratch remover from doing its job.

4. Apply Scratch Remover

Once you have tested it and washed your windshield, apply a small drop of the scratch remover to a clean, soft cloth. Gently rub the scratch in a circular pattern until it disappears or becomes less visible. Be especially careful not to apply too much pressure and cause new scratches and keep the scratch remover away from rubber moldings.

Does the Wd-40 Remove Scratches From Glass

All glass is susceptible to scratching. Cars are no exception, especially considering the daily abuse on roads and highways full of rocks, sand, salt, and other abrasive substances. Another consideration for windshields is the sun’s damaging ultraviolet rays which gradually break down the glass. With so many dangers along the roadways, it’s no wonder car windshields are so easily scratched.

Removing scratches from your windshield may seem impossible considering that most tools are made of metal, which only further damages the glass, mainly if you’ve ever used a screwdriver to try and remove a long scratch by hand! But that’s where WD-40 comes in.

This multi-purpose lubricating oil goes beyond just squeaking hinges and freeing stuck bolts. WD-40’s water displacement technology also makes it a helpful tool in getting rid of nasty scratches from your windshield.

Does It Work on Other Types of Windows as well

Removing windshield scratches is easier than removing scratches from other types of windows. That’s because the windshield, which is made up of laminated layers of glass, is much harder to scratch or damage. So if you have a particularly bad scratch on your car, there’s a good chance it can be removed easily using this method without replacing the entire windshield.

So if your car has windows in the back that are easy to scratch, try this on those too and see what happens! Removing scratches from laptop screens is possible as long as the screen is made using a similar method as a windshield (laminated glass). Unless you know for sure, it’s laminated, and you should replace it if you have a deep scratch on it.


When you need to remove deep scratches from your windshield, you must find the right solution for your specific type of glass. For example, if yours is a laminated windshield with an acrylic coating, specialized products are made specifically for this purpose.

Make sure you research what product will work best before trying anything on instinct. We hope this blog post has been helpful. If you want more information on how to remove deep scratches from windshield, then feel free to contact us!
