How to Solve Wiper Blade Chattering After Glass Coating?
3 Answers
Apply a water repellent. If the glass is not thoroughly cleaned, use a glass degreaser or glass polishing compound to remove the residue. If the issue is due to wiper blade wear, which causes uneven adhesion between the contact surface and the glass, simply replace the wiper blades.
Just after applying glass coating, the wiper blades are jumping? That's caused by the coating being too smooth, leading to uneven friction. You need to thoroughly clean the windshield with a dedicated glass cleaner or a solution of baking soda and warm water to remove residual coating and grease. If the jumping persists, it's likely that the wiper blades have hardened or worn out, so replace them promptly. Silicone or graphite-coated blades are recommended as they are more friendly to smooth surfaces. Check the wiper arm angle; if it's too loose or tight, gently adjust it with a wrench to ensure even vertical pressure. For routine maintenance, clean the wiper blades with a microfiber cloth every season to prevent dust buildup, and lift the wiper arms when parking to avoid sticking. Wiper jumping is particularly dangerous during high-speed driving, so address it promptly if noticed.
Last time I also encountered the issue of wiper blades jumping after coating. Simply put, the reason is that the glass surface became too slippery. Solution: First, try focusing on cleaning the windshield during car washing, using vinegar water or detergent-soaked cloth to scrub off any coating residue. If the problem persists, don’t hesitate to replace the wiper blades—opt for high-quality rubber or composite material blades for better durability. Check if the wiper arm angle is misaligned and adjust it manually if needed. Regularly clean the wiper blades and spray some water to lubricate them before driving to avoid dry wiping. Remember, jumping wipers impair visibility, especially during heavy rain at high speeds, so avoid driving in bad weather until the issue is fixed.
