How to Repair Scratches on Regular Glass?

[DeAustin]

Here are the methods to repair scratches on regular glass: 1. For shallow scratches, they can be removed by polishing. However, it is best to ensure that the scratches are not within the driver's line of sight, as polishing will cause some wear to the glass, and large scratch areas may also affect visibility. 2. For very fine scratches, toothpaste can be used for repair. Apply a small amount of toothpaste to the scratched area, wipe it gently with a soft cloth, and then rinse it with water. Toothpaste not only helps repair minor scratches but also prevents rust. Finally, it is important to note that cracks can expand due to temperature changes throughout the day, as heating and cooling cause the glass to deform. Continued driving exposes the damaged area to wind resistance, which further erodes the crack and adds continuous pressure, potentially enlarging the damage. For example, a few millimeters of crack in the morning can grow to several centimeters by evening if left unattended. Therefore, while it is possible to drive with scratches on the windshield, it is crucial to repair them promptly to avoid compromising the repair effectiveness.
