How to Repair Scratches on a Car's Windshield?

Clean the glass with a clean cloth to ensure there are no debris or impurities on the glass, and let the glass dry in a suitable environment. Take a clean, lint-free cloth and wring it tightly until no excess water drips, to prevent any debris on the cloth from rubbing against the glass and causing more scratches. Squeeze an appropriate amount of toothpaste onto the cloth, adding more if necessary. It is best to use toothpaste that contains baking soda as an ingredient, as it is most suitable for removing scratches. Move the cloth in small circular motions over the scratched area for 30 seconds, then rinse repeatedly with clean water.
I once had minor scratches on my windshield and fixed them myself using professional glass repair solution, which worked quite well. A repair kit only costs a few dozen yuan, containing polishing compound and buffing cloth. During operation, first thoroughly clean the glass surface to remove dust and debris, then evenly apply the polishing compound over the scratched area. Gently rub with the buffing cloth for a few minutes using moderate pressure—avoid excessive force—and the scratches will be significantly reduced. This method is suitable for shallow scratches, saving costs through DIY while gaining some experience. However, if the scratches are deep or located in the driver's line of sight, skip DIY and seek professional polishing or glass replacement to ensure nighttime driving safety. I also make a habit of parking away from branches or dusty areas to minimize the chance of new scratches.
