How to Repair Windshield Scratches?

For very small and shallow scratches, you can use toothpaste to remove them. Apply toothpaste to the scratches and rub back and forth, repeating the application several times. You can start with coarse wax, then apply fine wax, wiping in an outward direction from the inside. This method can help repair minor scratches. Clean the scratches thoroughly and then apply nail polish of the same color. Make sure the color matches exactly to ensure the repair doesn't look too unsightly.
Last time my car windshield got scratched by tree branches, I tried polishing it myself. You need to prepare glass-specific polishing compound, cleaner, and an electric polisher. First, thoroughly clean the scratched area to ensure no sand particles remain, then apply an appropriate amount of polishing compound and use the polisher at medium speed to rub in circular motions for about ten minutes. Keep adding water during the process to maintain moisture and avoid overheating. After polishing, wipe it clean with alcohol and check the results—superficial scratches will mostly disappear, while deeper ones will become lighter but still remain. Be careful not to touch the metal car frame while polishing to avoid scratching the paint. This DIY method is suitable for shallow scratches within two millimeters. If the damage is deep, you should go to a professional shop for resin filling, as driving with deep scratches can cause dangerous glare. The whole process takes over half an hour but can save you hundreds in repair costs.
