The glass is worn, how to polish it?

If the scratch is small and shallow, the user can treat it with toothpaste, squeeze a little toothpaste and put it on the rag to wipe the scratch repeatedly, and the effect will be more obvious.

If it is a small scratch, slightly deeper, you can use ammonia water to repair it, mix water and ammonia water evenly in proportion, and use a rag to repair the scratch.

The deep and large scratches in the main visible area of glass are not recommended to be polished and repaired. Because of the deep scratches, the polishing strength will increase correspondingly, and the glass wear at the scratches will be greater than that at other places, which will make the glass thickness thinner and cause visual distortion. Especially when driving at night, the incident light is easy to form an aperture, which will interfere with the line of sight and affect the driving safety. For the sake of safety, it is recommended to replace the glass directly.
