Why Do Windshield Wipers Break Easily?
2 Answers
Frequent outdoor parking exposes the wiper blades to intense sunlight or rain, accelerating rubber deterioration. Dry wiping or activating wipers before spraying washer fluid damages both the blades and windshield. Bird droppings, tree sap, and other debris on the windshield that aren't manually removed prior to wiper usage are primary causes of wiper failure. Detailed explanations follow: 1. Prolonged exposure to high temperatures heats the windshield significantly. With wiper blades constantly pressed against the hot glass, the rubber can scorch and degrade. Owners should park in shaded areas when possible and maintain wipers in their lowest position when not in use. 2. Always apply windshield washer fluid to moisten the glass before activating wipers. Windshields accumulate abrasive dust particles that require softening - dry wiping causes glass scratching and blade deformation.
I often encounter the problem of windshield wipers being prone to damage, mainly due to the significant impact of weather. I live in a hot climate area where the rubber blades of the wipers harden and crack under the scorching summer sun, resulting in a screeching noise and poor wiping performance. In winter, the frozen and stiff blades are prone to cracking. Loose or rusted wiper arm springs can cause uneven wiping, accelerating wear and tear. When parking outdoors, dust from trees or bird droppings sticking to the windshield can scratch the blades if wiped dry. It is recommended to regularly check the condition of the wipers and replace them every six months. When parking, prioritize shaded areas or use a car cover to block sunlight and reduce UV damage to the rubber material. Develop good habits: always spray water to clean the windshield before using the wipers to avoid dry wiping and damage. Safe driving should not be taken lightly—if the wipers don’t clear the windshield properly, address the issue immediately.
