How to Repair Glass Scratches?

[JudeAnn]

To repair glass scratches, first use a pen to outline the area that needs repair, then use strong light to illuminate and observe the scratches on the glass. Apply polishing paste evenly onto a wool wheel, then spread it over the area to be repaired. Start the angle grinder for polishing, sprinkle some water every 15 seconds, and allow 20 seconds for cooling. Finally, wipe off the polishing paste with a damp towel to complete the glass scratch repair.

There are scratches on the car glass. I've tried several methods to fix them. If they're not too deep, a simple DIY is enough. Usually, I first clean the glass surface to ensure there's no dust, then squeeze some toothpaste onto a soft cloth and gently rub it in circular motions over the scratched area. After several rounds of rubbing, the scratches can be smoothed out. Remember not to use gel-type toothpaste; regular white toothpaste works best. If the scratches are shallow, this method is cost-effective and convenient—I often do it at home with simple tools I already have. However, be careful not to mess with deep scratches or those in the center of the windshield, as it could affect visibility and make driving dangerous. If you're unsure, try buying a small repair kit, which includes polishing paste and a cloth. Be patient during the process and don't rush.

From a car repair perspective, dealing with glass scratches depends on their depth. Light scratches can be fixed with a professional resin kit—just apply it and cure it under a UV lamp for an instant smooth finish. It's easy to DIY. Medium-depth scratches might require a polishing machine, but even regular car owners can manage with borrowed tools. For deep scratches, it's safer to replace the glass entirely—don't skimp on safety here. When using tools, avoid high ambient temperatures, as poor curing leads to subpar results. I often recommend friends try an online kit first—costing just a few bucks, it's way cheaper than a dealership visit. The repair process is simple: clean, apply resin, cure with light, and wipe off excess—done.

After driving for a long time, glass scratches are common, and I rely on my own experience to fix them. Light scratches disappear with a little polishing—I used to try things like ashtray cleaners, but now it's better to just buy polishing paste. For deeper scratches, it's best to leave it to professional shops; resin filling is quick and effective, so don't skip it for convenience. When doing it yourself, pay attention to safety, especially eye protection. If the scratches are small and don’t affect visibility, take your time. You won’t save much money, but the sense of achievement is strong—just a cloth and a bit of paste will do. Avoid over-polishing, as it can damage the glass further.
