How to Repair Wiper Scratches on Glass?
2 Answers
Clean the glass with a clean cloth to ensure there are no debris or impurities on the glass, and let it dry in a suitable environment. Take a clean, lint-free cloth under warm running water. Wring the cloth tightly until no excess water drips. Squeeze an appropriate amount of toothpaste onto the cloth according to the size of the scratch, adding more if necessary. It is best to use white, non-gel toothpaste. Place the cloth with a drop of toothpaste on the scratched area and move it in small circular motions for 30 seconds. Check the scratched area to see the effect, repeating until the scratches are no longer visible.
After years of driving, I've encountered windshield wiper scratches several times. If the scratches aren't too deep, you can fix them yourself, such as by applying glass polish and rubbing it in circular motions with a clean cloth for a few minutes to smooth the surface. For deeper scratches, it's best to seek professional help as they have specialized grinding machines to reduce the marks; or simply replace the windshield—though more expensive, safety comes first. Prevention is key: regularly check wiper blades for embedded sand or rubber deterioration and replace them promptly (usually every six months). When washing the car, use warm water with dish soap to gently clean the glass and minimize scratch risks. Remember, impaired visibility while driving is extremely hazardous, especially during rainy nights, so timely repairs can prevent accidents.
