4 Answers
To repair scratches on a car windshield, follow these steps: Clean and wipe the area around the scratch thoroughly, use tape to outline the scratch to define the repair area, grind away the scratch with a polishing disc, then polish the glass with polishing paste to restore its shine. Apply windshield scratch repair agent along the crack, allowing it to seep into the crack. Alternatively, apply a small amount of toothpaste to the scratch, gently rub with a soft cloth, and rinse with water. Methods for maintaining a car windshield: Use specialized or appropriate wiper blades and replace them promptly to prevent scratching the windshield. Keep the windshield clean regularly. If debris is stuck, avoid using the wipers to remove it; instead, carefully remove it with a towel or other tools. Use automotive-specific glass cleaner to increase lubrication and reduce wear on the windshield. When attaching labels or stickers to the windshield, use static cling film. When parking outdoors in winter, it's best to cover the windshield with something, such as a car cover or a few sheets of newspaper. Avoid driving too closely behind large vehicles to prevent stones from being kicked up and hitting the windshield.
Last time there were scratches on my car's windshield, I fixed them myself and found it quite simple. I used a glass polishing kit that costs just a few dozen yuan. The steps were: first clean the surface with glass cleaner, then apply a little polishing paste to the scratch with your finger, and gently rub with a soft cloth for a few minutes until the scratch fades. Remember to apply even pressure and not too hard, or you might worsen the damage. This method works for small scratches; deeper ones require a professional shop. For maintenance, regularly cleaning the wipers can prevent such issues and make driving safer. Saving money on this allows for better tire or engine maintenance, killing two birds with one stone.
I've been working in the auto repair industry for many years and deal with glass scratches every day. Minor scratches can be DIY repaired with glass polishing paste - just apply and rub a few times for visible results. Deeper scratches require resin injection, which needs professional tools to avoid unevenness affecting visibility. The cost is low: DIY kits cost around 50 yuan, while professional shops start at 200 yuan depending on the scratch size. After repair, always check waterproofing to ensure no leakage during rain. Regular windshield cleaning is important - avoid using hard objects for scrubbing to minimize scratch risks.
As a veteran driver with 30 years of experience, I often see glass scratches. I've used DIY polishing methods with decent results, but it's best to do it on sunny days when the light makes scratches clearly visible. The materials are cheap and available at supermarkets. If the scratches are deep or affect driving, go straight to a repair shop without hesitation. Safety comes first—poor visibility at night can easily lead to accidents. The lesson is not to delay repairs; it can save big money and ensure safety.
