Sometimes car windows get scratched, and if they are left like this, these scratches can quickly become a safety issue. But not all scratches require a professional to repair, and there are many you can fix at home using a DIY method.

Scratches shallow enough not to catch your fingernails can be fixed using nail polish, cerium oxide, or a mix of baking soda and toothpaste. If you try one of these methods and it doesn’t work, then it may be time to seek the help of a professional to fix your window.

Curious about when it’s time to throw in the towel and get professional help? Let’s look at some methods for fixing scratched car windows and when it’s time for you to take your car in for a more extensive repair. 

Can You Repair a Scratched Car Window?

It is possible to repair a scratch on a car window at home. However, not all scratches are repairable, as some are too deep for the at-home methods and kits. 

You’ll need to run your finger over the scratched area to tell if your window scratches are shallow enough to be fixed. If your fingernail gets caught in the scratch, it is too deep for a home repair, and you need to take your car to be seen by a professional.

If you only see the scratches but can’t feel them when you run your fingernail over them, these scratches are shallow enough to be repaired.

What Supplies Will You Need?

Before you can fix your scratched window, you will need to gather some supplies. First, you need to collect the basic supplies listed below:

After you have these on hand, it’s time to choose a repair product. There are three options, and the one you select will depend on the state of the scratches on your car window. 

1.) Nail Polish 

Clear acrylic nail polish is an excellent method for filling shallow scratches. However, it only works on very superficial scratches, so anything slightly deeper and you need to choose another repair method. 

2.) Cerium Oxide

Cerium oxide is the most heavy-duty of the products, but you probably don’t have it hanging around at home. However, if you do, grab it because it works best for minor scratches. 

3.) Baking Soda and Toothpaste

Baking soda and white toothpaste can be one way to fix the scratches on your windows. While this method works, it also takes the longest as multiple applications are necessary. 

Remember, you only need to choose one of the above products to fix your scratch. Mixing repair methods is never recommended, and if your scratch is still visible after using one of the above methods, you should take your vehicle to a professional

Where to Buy a Glass Repair Kit

Besides just the above supplies, you can also purchase a glass repair kit. These kits usually contain everything you need to repair a window and use a resin material. They can typically be used for slightly larger cracks than the products listed above. 

There are several places to buy these kits, such as your local hardware store or home repair shop. If you don’t want to leave the house, you can order a glass repair kit like the Rain X Windshield Repair Kit (on Amazon)

For those that don’t have time to wait for a delivery, below are some shops where you can purchase window repair kits.

  • Walmart
  • Home Depot
  • Lowes
  • AliExpress
  • eBay
  • AutoZone

You can also check your local auto glass repair shop, as they typically also sell kits. 

DIY Steps for Repairing Scratches

Have all your materials on hand? Here are the steps for fixing the scratches in your window.

Step 1: Clean the Window

Use soap, a microfiber towel, and water to clean the scratch to ensure there is no debris in it. 

Step 2: Mark the Scratch

If the scratch marks on your car are very fine, then use a piece of tape on the other side of the window to mark where they are. 

Step 3: Mix Your Repair Product

For those using cerium oxide, follow the instructions on the bottle. If you are using toothpaste and baking soda, mix 1 tsp baking soda with about an ounce of toothpaste and some water to make a paste.

Those using nail polish can skip this step.

Step 4: Fill the Scratch

Fill the scratch with your desired product

Step 5: Wipe or Buff

If you used nail polish, it’s time to wipe away the excess. If you used either of the other two methods, buff the area where you filled the scratch gently until smooth. 

Step 6: Clean the Window

Once you finish step 5, clean the entire window, and the scratches should no longer be visible! 

When Should You Hire a Professional?

If you have tried any or all of the above methods and the scratches are still on your car window, it’s time to hire a professional to help. 

Also, remember that if your scratches are deep, to begin with (enough to catch your fingernail), then you need professional help, and you shouldn’t attempt any at-home methods

What is the Cost of Replacing a Windshield?

The cost of replacing your windshield can vary based on your location and the type of car you drive. You may also pay more if you pay for the auto glass service to come to you rather than you coming to them. 

Before you book a service to repair your windshield, call around and get a couple of quotes. In general, replacing your windshield should cost between $200 and $500, but it might be more if you ask for special services. 

Remember that you get what you pay for, and sometimes, paying a little extra for a service that comes to you while you are at work can save you a hassle. 

Final Thoughts on Fixing Scratches on Your Car Windows

Overall, if you find scratches on your car windows, it is possible to fix them yourself as long as they aren’t too deep. You can use a few different methods, from buying a kit to using items you already have around the house.

If you find that they are pretty deep or the home methods don’t work, then it’s time to seek the help of a professional.
