What Causes the Squeaking Sound When New Car Wipers Scrape the Windshield?

[DiZoe]

New car wipers squeaking when scraping the windshield is caused by foreign objects between the wiper blades and the windshield, which create sharp noises due to friction. In this case, you can check and clean any debris on the wiper blades or underneath them to ensure the wiper area is clean. Wiper maintenance tips: 1. Avoid prolonged contact with the windshield: After parking, lift the wipers to prevent them from sticking to the glass for extended periods. Especially in scorching summer temperatures, the rubber blades pressed against the glass can easily deform or lose elasticity due to heat. 2. Repair windshield damage immediately: Road debris like gravel can easily chip the windshield, but minor dents are often overlooked. These not only damage the wipers but may also lead to full windshield cracking. It's best to have a professional auto detailing shop inspect or repair such damage. 3. Use rubber protectant: Rubber protectants available in the market resemble marker pens and are often included as freebies with cleaning products. Applying them to wipers enhances lubrication and extends the elasticity of the blades.
