Having windshield scratches on your car is a nuisance. It is not only annoying but can be dangerous as well.

Step 1: The Deepness of the Scratches

The new windshield wipers rarely cause any scratches. You may see scratches due to old wipers. Before removing scratches from the screen, you must know how deep the windshield scratches are. The efficient way to do that is to use your fingernail to check the depth of the scratch. 

Move your fingernail along the windshield scratch marks.

The surface will be smooth and not edgy if the scratches are minor. However, if your fingernails are getting caught, then it means that the scratch is deep and groovy. You should wear a pair of protective gloves while checking the windshield scratches. The gloves will protect your fingertips from being cut by the glass. 

If the scratch is minimal, you can remove them by polishing the glass. However, if the windshield scratch marks are too deep, you should address the situation as quickly as possible. Over time, the deep scratches can cause your windshield to weaken.

Step 2: The Glass Repair Kit

A glass repair kit is the most professional solution to remove windshield scratch marks. Rather than using household tips and tricks for removing scratches, it is better to go for a more permanent solution. You can buy the glass or windshield repair kit in two ways which are:

Before you use the glass repair kit, you should clean your car windshield first. Start the work in a shaded space with a moderate temperature. Do not stay in the open sunlight until the repair is done.

Use soap and water mixture to clean the car thoroughly. It will help remove any debris or dirt off the windshield giving you a much smoother area to remove the scratches.

Then take a clean microfiber cloth to dry the windshield properly. Do not apply any compound unless the screen is completely dried. Otherwise, the compound will not work on the sloppy, wet surface.

Step 4: Applying the resin

Take a start from one end of the windshield scratch mark, and dispense the crack resin directly onto the scratch. Now, from a 45-degree angle, closely look at the scratches. You will see a dark area wholly covered with the resin.  

However, applying light pressure from the inside of the windshield is advisable if you see any air pockets in the scratches. You should only apply pressure on the sides and center of the windshield scratch.  

The crack resin will stop the scratch from getting any deeper and prevent water and debris from getting inside. Lastly, apply curing strips to the entire area where the resin is used.

Step 5: Move Your Car

Once you have applied the crack resin and the curing strips, move your car into the sunlight to dry the glass. If there is not enough sunlight or the weather is cloudy. You can also use the following to cure and dry the resin:

  • Ultraviolet light  
  • Ultraviolet radiations  

The resin will merely take 15 to 20 minutes to dry out. There is no need to leave the car in the sunlight for too long.

Step 6: Remove the Hardened Strips

You can now remove all the strips when the resin has been absolutely dried. However, if the strips are wet, you want to let them sit for a more extended period. 

When you’re sure the crack resin is completely dried, use the razor blade. You will set a 90-degree angle and scrape the hardened resin away.  

You do not have to apply any pressure whatsoever at this point. The blade has enough power to cut the hardened resin without any pressure. There is no need to worry if you see any white flakes, as it is normal to get white flakes when scraping.  

Lastly, clean the area with a soft cloth to remove any extra material. It is the last step in removing scratches from the windshield. You can also polish the entire windshield after to make the surface more even.
