What Causes the Squeaking Noise When Wipers Scrape the Windshield?

[StAddyson]

The reasons for the squeaking noise when wipers scrape the windshield are: 1. If the front windshield is not cleaned for a long time, dust can accumulate, making the surface rough. During the wiping process, the wipers not only fail to clean effectively but can also cause scratches on the glass; 2. After exposure to wind and rain, dust from the air can settle into the wipers. Using wipers with sand particles to wipe the windshield is like using a grinding wheel on the rubber blades. Over time, the rubber blades wear out, becoming rough, which leads to ineffective cleaning and squeaking noises. Wipers are tools on the front glass of motor vehicles designed to prevent rain and other debris from obstructing the driver's view by performing simple cleaning.
