How to Deal with Scratches on the Car's Front Windshield?

Small and shallow scratches can be removed by polishing. It's best if the scratches are not within the driver's line of sight, as polishing will cause some wear to the glass. You can also apply toothpaste to the scratched area, wipe it gently with a soft cloth, and then rinse it off with water. Toothpaste can help repair minor scratches. If the scratches on the glass are deep, it is recommended to choose a reliable and reputable professional repair shop for restoration.

My car's windshield had scratches before, when it got hit by a small stone on the highway. I tried polishing it with toothpaste, but the effect was mediocre. Later, I learned that shallow scratches can be treated with special glass polishing paste. I bought a kit and followed the instructions to slowly polish in circles for half an hour, then wiped it clean with a soft cloth. The scratches really faded a lot. However, don’t force it with deep scratches—over-polishing can thin the glass and affect its strength. When parking, I try to avoid parking under big trees, as the acidic substances in bird droppings can corrode the glass surface. These small habits can help prevent scratches from appearing.

I'm particularly concerned about scratches on the windshield. Last time, even a slight scratch caused uncomfortable glare from sunlight refraction while driving on a sunny day. I consulted mechanics at the auto repair shop, and they said there are three levels of solutions: use cerium oxide polish for micro-scratches, employ a small grinder for moderate scratches, and replace the entire glass if it's deep enough to catch your nail. I ultimately opted for professional polishing, which cost 200 yuan but worked well. As a side note, avoid using hard cards to scrape off ice in winter—using dedicated de-icing spray can reduce the risk of scratches.

Old Li's car windows were covered with scratches. He bought some repair fluid himself but couldn't fix them after trying for a long time. I recommended him to go to a professional shop, as resin filling technology works best for deep scratches. If left untreated, these scratches can easily worsen when the wipers scrape back and forth on rainy days. When washing the car, always rinse off the sand particles first before wiping, as dry wiping is like sanding the glass with sandpaper. A while ago, my car got a scratch from a tree branch, but after applying glass repair agent thinly three times, it became almost invisible.
