What are the reasons for the noise between the wiper and the windshield?

The reasons for the noise between the wiper and the windshield are: 1. Wiper issues, such as aging, hardening, or prolonged lack of contact with water, causing dry wipers to produce noise during operation; 2. Foreign objects between the wiper and the windshield; 3. Deformation of the linkage mechanism; 4. Incorrect angle of the wiper arm. The solutions to the noise between the wiper and the windshield are: 1. Spray windshield washer fluid before use to prevent dry friction; 2. Regularly remove dirt and debris from the wiper; 3. Replace the wiper; 4. Recalibrate the position of the wiper arm; 5. Replace the linkage mechanism. The function of the wiper: to scrape off raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and increasing driving safety.
I've encountered the same issue before, and later found it's mainly related to windshield cleanliness. An oily film tends to accumulate on the windshield surface, especially for cars parked under trees which are prone to sap stains that rainwater can't wash away, forming spots. The wiper blades then make squeaking noises when rubbing against these spots. Newly replaced wipers might also produce abnormal sounds due to improper installation, such as loose clips causing vibration noises during the return stroke. Aging and cracked rubber blades are also common - if the rubber edges crumble when scraped with a fingernail, it's time for replacement. Spraying some windshield fluid before wiping during rain can help cushion the noise. When parking, it's best to lift the wipers to prevent rubber deformation. These are all insights I've gained through daily commuting.
