How to Deal with Wiper Rubber Squeaking?

[VonAmy]

There are 4 methods to handle wiper rubber squeaking: 1. Check for any foreign objects between the wiper blade and the windshield: If there are any, remove them; 2. Inspect the rubber part of the wiper blade for hardening, burrs, gaps, cracks, or tears: If such issues are found, replace the wiper blade. If there are only burrs, you can gently sand them twice with 1000-grit sandpaper and test; 3. If the wiper blade is ruled out as the cause, perform a water spray test on the windshield: If you notice areas where water does not adhere or spreads too quickly, it indicates the presence of an oily film on the windshield. In this case, use a degreaser or adhesive remover for cleaning; 4. If the squeaking is caused by uneven force distribution during the wiper's back-and-forth motion, you can remove the wiper blade: Place a piece of cardboard on the windshield, slowly lower the wiper arm onto it, and check if the lower plane of the wiper arm makes full contact. If there is an angle, it means the wiper arm is deformed and can be adjusted with a wrench to correct the angle.
