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.

When encountering glass scratches, I first consider safety factors. Minor scratches refracting sunlight can distract the driver, especially in severe weather conditions, making it even more dangerous. Therefore, timely repair is crucial: clean the glass with alcohol to remove dirt, then apply glass repair fluid to fill the scratches. Use a plastic scraper to spread it evenly, wait a few minutes for it to cure, and then wipe it clean with a cloth. DIY repairs are simple but only suitable for shallow scratches. If the scratches are in critical areas like the center of the windshield, it's best to seek professional repair to avoid improper polishing leaving residues that obstruct vision. After repair, nighttime driving becomes safer, and it also prevents rainwater accumulation from corroding the glass. It's recommended to check the glass condition during annual vehicle inspections, as fixing minor issues early can prevent bigger problems.

For minor scratches and wanting to save on repairs, I often try simple DIY methods. Apply white toothpaste or a baking soda paste onto the scratch, then use a dry cloth to polish in circular motions for two minutes—this can alleviate light marks. If the effect isn't noticeable, purchase a bottle of glass polish for just over ten yuan, dip a soft cloth, and gently rub manually for a few minutes. Avoid using sandpaper or high-power tools to prevent damaging the glass. For deep scratches or large areas, professional service is recommended, costing just a few dozen yuan to fix. In the long run, replacing wiper blades to prevent scratches is more cost-effective, and maintaining good glass care saves on repair costs.

For minor scratches, I recommend using a dedicated glass repair fluid. First, thoroughly clean and dry the glass, then apply the repair agent to fill in the scratches. Use a plastic scraper to spread it evenly, and place it under sunlight or UV light to cure for five minutes until hardened. Then, gently scrape off the excess with a blade and finally polish with a cloth. The entire process requires precision and patience, and it only works for surface-layer damage—deep scratches won't be fixed. Be careful not to let the liquid flow to the edges during application. Once completed, the transparency will be restored, ensuring clear visibility while driving. Choosing a reputable brand of repair fluid is crucial—opt for those with many positive online reviews.
