I often encounter glass scratches on my car and would like to share my DIY repair experience. For minor scratches, I first clean the dust off the glass surface, then purchase a glass repair kit from the supermarket—it contains polishing compound and special cloth strips. After applying, patiently polish for five to ten minutes, and the results are quite good, restoring transparency. For deeper scratches, a step-by-step approach is needed: lightly smooth the surface, apply resin liquid, let it cure, and then polish. When doing it yourself, use a soft cloth for gentle wiping—avoid hard objects or low-quality cleaners to prevent secondary damage. From a safety perspective, don’t delay fixing scratches in the main viewing area of the windshield, as light reflection may affect driving visibility. I’ve tried this method several times—it’s low-cost and hassle-free. I recommend regularly checking the glass condition to prevent small issues from worsening. If you’re not confident in DIY, seeking professional help is more efficient but slightly more expensive.
