With over a decade of experience in car repair, the approach to glass scratches depends on their depth. For shallow minor scratches, you can handle them yourself using a glass scratch repair compound. First, clean the glass with a clean cloth, apply some repair compound to the scratch, and use a polishing sponge to buff in circular motions for about ten minutes. Finally, wipe it clean. Deeper scratches are more troublesome to fix, requiring professional tools for grinding and polishing—it's best to leave these to an auto repair shop. For the deepest scratches that affect visibility, especially when driving into the sun causing glare, it's better to replace the glass entirely. Though more expensive, safety comes first. After treatment, it’s advisable to apply a glass water repellent spray—rainwater will wash right off, giving you clearer visibility while driving.
I used scratch wax to deal with the scratches on my car glass. I bought a box online for just over ten yuan. After parking at night, I cleaned the scratched area with a wet cloth, applied a coin-sized amount of wax on the scratch, and used a sponge ball to rub it in circular motions along the scratch for about five minutes until it faded. The key is to keep your hand steady and avoid applying too much pressure to prevent damaging the glass. After treatment, remember to wipe the area with glass cleaner twice to avoid leaving wax residue. If you're not confident doing it yourself, many car accessory shops now offer repair services, usually costing around a hundred yuan, which is much more cost-effective than replacing the entire glass. By the way, avoid parking too close to green belts, as tree branches are the main culprits for scratches.
