What is the reason for the loud noise from the wipers of a new car?

[McNorah]

The loud noise from the wipers of a new car is caused by an incorrect fitting angle. The solution to this issue is to adjust the fitting angle between the wiper arm and the windshield. Wipers are essential accessories installed on the windshield, designed to clear rain, snow, and dust that obstruct visibility. Features of wipers include: 1. Corrosion resistance; 2. Strong water repellency and excellent adhesion to the windshield; 3. Heat, cold, and acid/alkali resistance. Methods for maintaining wipers: 1. Always use windshield washer fluid when operating wipers on sunny days—avoid dry wiping; 2. Manually remove any stubborn or hard debris on the glass; 3. Lift the wiper blades when washing the car or performing routine cleaning, holding them by the spine; 4. In winter, use an ice scraper to remove ice from the windshield before using the wipers.
