Most wiper blades are composed of rubber or rubber and polymer plastic combinations. These materials can deteriorate or wear down over time, allowing the metallic wiper arm to come into contact with windshield glass. This can result in scratches or other damage to windshields.
Maintaining wiper blades and arms in good working condition can ensure greater longevity not only for these safety components but also for windshield glass. Wiper blade maintenance is a relatively simple process that includes the following activities:
- Perform an inspection of your wiper blades at least once per month to ensure that they are still seated properly and that they touch the windshield evenly at all points along their length. If any structural damage is present, it may be time to replace your windshield wipers.
- Clean your windshield wipers with a soft, dry cloth regularly. This can remove any small fragments of leaves or debris that may have collected on the blades during your daily drive.
- Depending on your preferences, vinegar or dish soap and water can be used to clean windshield wipers every six months. This can significantly increase the longevity of wiper blades by removing chemicals and other impurities that can cause deterioration of rubber and plastic polymers.
After each cleaning process, spraying a small amount of rubber protectant onto the blade can help it to retain elasticity and can improve performance on the road. This can help you to see more clearly even in torrential rainstorms.
