How to Repair Car Glass Scratches?
2 Answers
There are several methods to repair car glass scratches, including glass scratch repair agents, grinding removal method, professional repair shops or 4S stores, and toothpaste removal method. Below are the detailed introductions: 1. Glass Scratch Repair Agent: When the vehicle's glass scratches are minor and not severe, you can choose to purchase a bottle of glass scratch repair agent. First, clean the area around the scratch thoroughly, ensuring there is no moisture or dirt. Then, gently apply an appropriate amount of the repair agent along the scratch and use a leather cloth to repeatedly wipe the glass until the scratch becomes less noticeable. Finally, clean the area with a cloth sprayed with cleaning solution. 2. Grinding Removal Method: When the scratch area is small and the depth is shallow, you can use specialized glass sandpaper designed for polishing glass. Ensure both the glass and the sandpaper surface are clean and free of dust and sand particles. Gently rub the glass surface with the sandpaper while spraying an appropriate amount of clean water to prevent the glass from overheating. However, this method is not suitable for the car's front windshield, as grinding may cause some degree of damage to the glass and affect the driver's visibility. 3. Professional Repair Shop or 4S Store: When the car glass scratches are large or severe, it is best to take the car to a professional repair shop or 4S store for expert repair, which ensures good results and high safety. 4. Toothpaste Removal Method: Toothpaste can remove minor glass scratches because it contains fine titanium oxide particles, which are harder than glass. These particles can not only polish our teeth but also help with small glass scratches. First, clean the glass thoroughly, then squeeze some toothpaste onto a clean cloth and repeatedly rub the scratched area. You will notice that the scratch has disappeared or become less visible.
I also encountered small scratches on my car glass last time, which were caused by sand on the highway. First, I used a damp cloth to clean the glass thoroughly, ensuring there were no dust particles. Then, I bought a bottle of glass polish, which was quite cheap, costing only a few dozen yuan. I applied a small amount to the scratches and gently rubbed in circles with a clean polishing cloth, being careful not to press too hard to avoid damaging the glass. After about a dozen rounds of polishing, I noticed the scratches became lighter. The whole process was like doing a craft project, quite therapeutic. If the scratches were deeper, I would consider using a professional repair kit, such as UV-curing glue—applying the glue first and then hardening it with a UV lamp. Finally, remember to clean the windshield regularly using a soft cloth instead of rough materials to prevent many scratches. DIY repairs save money and teach some skills, but for deep scratches that affect safety, it's best to visit a professional shop.
