How to eliminate the squeaking noise when new wipers scrape the windshield?

This indicates that the wiper arm is twisted upward. Let the wiper stop in the middle position, then use a wrench or pliers to grip the wrapped part and twist it downward a few times. Wiper blades are rubber products. After being used for a period of time, they may age and harden. Replacing them with new wiper blades will solve the problem. Car owners can check and clean any foreign objects on the wiper blades or underneath the wipers to ensure the wiper blade area is clean.
I've experienced this situation before - the squeaking sound from new wiper blades on the windshield is really annoying. Remember to thoroughly clean the windshield first, using a dedicated degreaser to scrub twice, as residual stains can increase friction noise. Check if the wiper arm spring is too tight or too loose; manually adjusting the angle by bending it usually helps. If the noise occurs on rainy days, try turning on the front defroster to warm up the glass and reduce dry friction between the rubber and cold glass. By the way, spray some WD-40 on the wiper blades for lubrication, but don't apply engine oil directly as it will corrode the rubber. Make sure to firmly secure the base during installation - last week I reinserted and fixed mine, and the noise disappeared.
