Clean the glass with a clean cloth to ensure there are no debris or impurities on the glass, and let it dry in a clean environment. Take a clean, lint-free cloth that is as smooth and non-shedding as possible, wring it tightly until no excess water drips out. Squeeze an appropriate amount of toothpaste onto the cloth according to the size of the scratch, adding more if necessary. It's best to use white, non-gel toothpaste, which is most suitable for removing scratches. Move the cloth in small circular motions over the scratched area for about 30 seconds, then rinse with clean water.

I've been repairing cars for many years and have seen plenty of windshield scratches. If the scratch is shallow and hasn't damaged the inner layer, a glass polish can usually fix it. First, thoroughly clean the glass and dry it with a lint-free cloth. Then, apply the polish to a polishing pad and gently rub in circular motions for a few minutes, using even pressure without being too forceful. After polishing, rinse it clean, and the results are usually good. For deep scratches, don't attempt this—it can make things worse and even compromise the glass's strength. When washing your car, always use a soft brush or professional tools, avoiding rough cloths or scrubbing in areas with a lot of sand or dust. Remember, minor scratches that don't obstruct your view can be repaired, but if there's a crack or hole, it's essential to visit a professional shop for a replacement. Don't skimp on safety for the sake of saving a few bucks. I've also seen friends damage their windshields with worn-out wiper blades—so regular inspections are crucial.

I once had my windshield scratched by a tree branch and had it handled at a roadside shop. The technician told me that small scratches could be DIY-repaired with a repair solution, but to handle it gently to avoid worsening the problem. Before repairing, wash the glass with soapy water, apply transparent tape to mark the spot, then drip a few drops of the repair solution and polish it repeatedly for about half an hour. The effect varies with the depth of the scratch—shallow ones can be fixed by 70-80%. If the scratch is too deep or affects visibility, I recommend going directly to a professional service. They have special equipment for more thorough polishing, usually costing a few hundred yuan. When driving, be mindful to avoid splashing gravel or letting wipers run dry, as these are common causes. Regular of wipers and using high-quality windshield washer fluid can also reduce the risk of scratches. Leaving a scratch untreated can cause glaring reflections in sunlight, compromising driving safety.

I've tried fixing small windshield scratches myself, like using toothpaste or a dedicated scratch repair pen. Choose white toothpaste without abrasive particles, apply it on a cloth and gently rub for a few minutes, then rinse to check the results. This method is cost-effective and simple, working decently for fine shallow scratches. If the effect isn't noticeable, purchase a repair kit from auto shops - the kind with polishing pads - the operation takes less than half an hour. Remember to wear gloves for protection and avoid getting dust in your eyes. Scratches are often caused by improper cleaning or leftover insect residue, so avoiding dusty roads while driving helps. After repair, the clarity improves significantly without affecting night visibility, but don't push your luck with deep scratches - if it feels problematic, visit a professional shop.

As someone who frequently deals with car glass, I believe windshield scratches can be divided into two categories for treatment. Superficial scratches are caused by external abrasions and can be smoothed out using glass polish, with tools including manual sanding pads or electric polishers. Keep the surface wet during operation to avoid dry grinding, which could generate heat and damage the glass. Deep scratches involve the inner layers of the glass, where polishing may fail and require replacement. Scratches are often caused by worn wiper blades or roadside debris, so it's important to regularly remove debris before washing the car as a preventive measure. After repair, check if the transparency is restored to its original state. Any scratches that obstruct the view must be promptly replaced to ensure driving safety is prioritized.

I'm very safety-conscious when driving, and even small windshield scratches can be quite annoying. During rainy days, water gets trapped in the scratches, blurring visibility, while strong sunlight causes more glare, making it easy to get distracted and cause accidents. For minor scratches, you can first try using commercially available repair kits—opt for those with tutorials for easier operation. Before starting, ensure the glass is thoroughly cleaned, and patiently polish for 10-15 minutes without rushing. If the results aren’t noticeable, don’t force it, as this could worsen the issue and affect driving. When parking, avoid areas under trees or gravel lots, and use mild cleaning agents when washing the car. After scratch repair, the glass will be clearer, but deep scratches may require professional treatment or replacement—spending a bit for safety is worth it.
