Scratches are usually microscopic compared to the overall thickness of the windshield. Scratches are more often a visibility nuisance than a risk factor that could lead to further damage or breakage. The importance of clear vision plays a significant role in the safety of yourself and those around you. When not addressed, scratches can accumulate causing un-needed glare in the eyes of the driver. Some preventative maintenance and care can keep scratches from accumulating. Regular cleaning both the windshield and your windshield wipers will minimize the small particles of dirt that are often responsible for scratches. Remember to never operate your windshield wipers on a dry windshield. Small scratches can be removed from the glass by using a polishing agent such as Bon-Ami. Deep scratches often need to buffed out with industrial equipment and a materials such as cerium oxide. However, removing a deep scratch within a concentrated area can cause the windshield surface to distort and become uneven. This can lead to other problems such as optical distortion causing driver’s eyestrain and poor visibility.
