The good news is that there are a few simple solutions to remove glass scratches at home. In the following part, we will look into different methods of car glass scratch repairs.
Minor car glass scratches can totally be removed at home
1. How is car glass made?
Before getting into the details of how to repair the glass scratches, it is important for us to grasp some ideas about the making of car windshields. Since the windshield has a special structure compared to the normal glass, it will require different methods to take care of.
Unlike regular glass, the windshield is laminated glass, a type of glass that can ensure higher safety. It will not cause harm to the people sitting inside as well as the pedestrians in case of car accidents.
Laminated glass is made of three layers, two layers of glass and a vinyl sheet in between. These layers are glued under high heat and pressure in order to make these layers inseparable. Thanks to this structure, the outer layers will experience all the harm and damage without damaging the inner layer, given that the impact is moderate. Moreover, it also means that the scratches on the outermost layer can be fixed without requiring a costly windshield replacement.
Except for the visible and noticeable major scratches which can be seen easily, some scratches are hard to see. It might take some extra steps to locate where the scratches are. Using your bare eyes will take forever to scan through the entire glass body and it is possible that you will miss out on some unnoticeable damages. Here is one tip for you to easily locate the glass scratches: You can run your fingers or fingernail across the surface. This way you can scan through the glass without missing out any spot that needs to be fixed.
Determine how deep the scratch is
Each time you find a scratch, the next step is to determine the depth of the scratch to decide if it is fixable. If your fingernail gets caught, it is a sign that it is impossible to undo the scratches. In this case, you should seek professional help. Deep scratches can get worse over time. Without timely intervention, the windshield can shatter and cost a greater cost to replace the entire windshield. For a minor scratch, you can still run your finger smoothly.
Mark the scratch
Once you identify a scratch, whether it fixable or not, you should mark it and fix it as soon as possible. Try to mark the spot with tape or a dry-erase marker.
Apply the product
After locating, accessing and marking scratch, you now can get down to the main task of fixing the damaged area. There are a few measures to solve this problem.
Glass repair kit
For those who prefer an effective and comprehensive method to remove the scratch, a glass repair kit is highly recommended. You can purchase one from most car parts and accessories stores. The glass repair kit is powerful in the way that it can be used to treat fairly deep scratch which is not so detrimental to the windshield’s integrity. You can apply the glass repair kit by the following process:
Apply the rubbing compound from the repair kit to the scratch. Comprised of cerium oxygen, the rubbing compound will react with the glass, forming the cerium oxygen glass compound which can seal the scratch. After applying the rubbing compounds, wait for around 30 minutes. When the wait is over, now use a soft cloth to clean the area.
Transparent Nail Polish
Another handy product that can be used to undo the scratch on the windshield is nail polish. However, it only works for minor scratches. Just apply the nail polish on the surface, clean the excess and wait a couple of minutes until it completely dries out. You can also use the nail polish remover to get rid of the excess entirely. It should be noted that nail polish should be transparent.
Toothpaste is a common alternative that is usually utilized to remove the glass scratch. However, just like nail polish, toothpaste is not reliable to repair a deep scratch. What the toothpaste do is to remove the edge around the scratch, hence smoothening out the glass surface and making the scratch disappear.
First off, you should clean the surface where it needs to be repaired and make sure the surface is completely dry. Then apply the toothpaste to the area and use a soft cloth to rub around in circular motions for less than 1 minute. Wipe the excess with a damp cloth until the surface is free of any excess. Now, you basically eliminate all these small scratches. Toothpaste is easy to find and barely cost you any penny.
This product can be found in some automotive part stores or online stores. This product will cause a chemical reaction with the glass, filling the scratches and restore the original condition. First, apply the product onto a cloth and use it to rub around the scratch for one minute. Remember to not buff the surface excessively. Then let the remover sit in place and work on its own for 30 minutes. Complete the process by cleaning the excess.
Glass scrub compound
Cerium oxide is the main substance that is used in most glass scratch remover products. For those who don’t know, cerium oxide comes in the form of power. So instead of using the power right away.
The glass scrub compound contains a high concentration of cerium oxide that can help to remove the scratch. It works in a similar manner to toothpaste. To erase the blemish, you apply some compound on damp fibre clothes. Next, you rub the scratch area in circular motion a few times. Make sure the pressure is attributed even across the surface. Spray water to the area as you go. It is important to keep the surface damp while you are rubbing. Do it repeatedly for a few times in a couple of days. Glass scrub compound will take you more time than other methods and require you to be extra careful. However, the outcome is rewarding if you can apply it correctly.
It should be noted that this substance can be abrasive, you should use it carefully and don’t use it for too long. Other than fixing the scratches, a glass scrub compound can also be used to remove stubborn grimes and dust on the glass surface.
