How to Repair Minor Scratches on Car Glass?
2 Answers
Purchase a specialized polishing machine with polishing compound, apply resin coating, or use glass cleaner. Below are relevant methods for car glass repair: 1. Purchase a specialized polishing machine with polishing compound: Visit a professional auto repair shop to buy a specialized polishing machine with polishing compound for removal, but this can only eliminate minor scratches. 2. Resin coating: Using resin with a refractive index close to that of glass is an emergency solution, but it can only be used to repair very small pits. 3. Use glass cleaner: There is a wide variety of glass cleaners available in the domestic market, mainly categorized into three types: summer glass cleaner, winter antifreeze glass cleaner, and special antifreeze glass cleaner. Among them, summer glass cleaner is primarily used to remove insect residues from the mirror surface.
Minor scratches can be quite annoying, but don't worry—I've dealt with them many times myself. First, thoroughly clean the glass surface with warm water and a bit of dish soap, then dry it to ensure there's no dust or grease. Next, apply a specialized automotive glass polishing compound and gently buff the scratched area with a soft cloth or a low-speed polishing machine. Use even, gentle motions to avoid worsening the scratches. After a few minutes of buffing, wipe it off to check the results—you may need to repeat the process two or three times. This DIY method works well for shallow scratches, and the tool kit can be found online for around 20 yuan. For deep scratches or those in the direct line of sight on the windshield, it's best to seek professional help. Remember, polished glass becomes clearer, reducing glare while driving and improving safety. Wearing protective goggles during the process is crucial. Many scratches are caused by worn wiper blades, so replacing them regularly can help prevent future issues.
