How to repair the scratches on the window glass?

Secondly, because grinding will wear the glass and may affect the driver's sight, the area where scratches are removed should not be in the driver's sight. If the scratched area of the automobile windshield is just within the driver's line of sight, it is recommended that you replace the glass as a whole.

Precautions for maintenance of front window glass

In order to save money, many car owners use detergent or soapy water as car glass water, which is actually incorrect. Professional automobile glass water can not only play a cleaning role, but also reduce glass wear.

Before starting the wiper, make sure that there are no hard objects such as sundries attached to the wiper and the glass, and start the glass to spray water first to play a role in lubrication. This step is very important to avoid most glass wear.
