The method for repairing scratches on the front windshield of a car is: 1. Clean and wipe the area around the scratch, use tape to surround the scratch to define the repair area and avoid damaging other parts during grinding; 2. Use a grinding pad to grind away the scratch, then polish the glass with polishing paste; 3. For small and shallow scratches, you can directly polish them without grinding; 4. If you don't have a grinding pad, you can use toothpaste as a substitute, as toothpaste contains abrasives that can achieve a grinding effect. The maintenance methods for the front windshield are: 1. Use suitable wiper blades and replace them in time; 2. Keep the front windshield clean regularly; 3. Use windshield washer fluid to increase lubrication and reduce wear on the front windshield; 4. When using the wipers in the rain, wipe off dust and other debris from the windshield.
I always repair the scratches on my car's windshield by myself because I find it both cost-effective and convenient. First, if the scratch is not deep and only a surface mark, I usually buy a glass repair kit, which is available online or at auto parts stores for about a hundred yuan. The steps are simple: thoroughly clean the glass surface to ensure there is no dust or grease, then slowly fill the scratch with the resin from the kit, cure it with a UV lamp for about ten minutes, and finally scrape it smooth with a blade. I’ve tried it several times myself, and the results are quite good—the repaired area is almost invisible. However, it’s important to note that this method isn’t a cure-all; it’s only suitable for very shallow scratches. If the scratch is too deep or in a critical line of sight, I won’t risk DIY repairs, as improper handling can cause the crack to expand and affect driving safety. I also pay attention to prevention in daily life, such as avoiding scraping the glass with hard objects and using a soft cloth to wipe it gently during cleaning, to save myself the hassle later on.
From a professional standpoint, I take the repair of windshield scratches very seriously in terms of specific techniques and outcomes. Generally, scratch repairs fall into two categories: minor scratches can be directly fixed with resin, while deeper scratches or cracks may require glass replacement. I assess the depth and location of the scratch—if it's very shallow, I personally use specialized tools like resin injectors, a process that requires precise control to ensure the resin flows properly without leaving air bubbles. Deep scratch repairs carry higher risks as they can weaken the glass structure and impair driving visibility, especially at high speeds or at night, posing safety hazards. Therefore, I recommend that car owners, upon discovering any scratches, visit a repair shop for inspection with professional equipment to confirm safety before deciding on repairs. For minor scratches, the cost is relatively low, just a few hundred yuan; but if the damage spreads, replacing the windshield could cost thousands and cause significant downtime. Regular maintenance, such as avoiding dirty car-washing tools, can greatly reduce such issues.
