Solutions for wiper blades making glass scraping noise: 1. Replace the rubber blade; 2. Spray windshield washer fluid before use; 3. Clean the wiper blades regularly. This issue may occur due to deformed wiper blades, aged rubber blades, or contaminated glass with debris. However, wiper blade deformation is rare, and if this problem occurs, it should be replaced at a 4S shop. Wiper blades are sheet-like structures installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly, mainly used to clear rain, snow, and dust that obstruct the view on the windshield.

I've been driving for many years and often encounter the issue of wiper blades squeaking on the windshield. This noise is mostly caused by a dirty windshield or oil film, such as when parked under trees or with bird droppings left uncleaned. I usually start by thoroughly washing the windshield with warm water and dish soap, using a microfiber cloth to scrub off the dirt and ensure no residue remains. If that doesn't work, I check the wiper blades: if the rubber is aged, cracked, or has gaps, I replace them with new ones; if undamaged, I clean the blade strips with alcohol to restore their elasticity. During installation, I press them gently to ensure they adhere tightly to the windshield. These minor fixes are quick and easy to do yourself—after all, how dangerous is it to have poor visibility during rain or snow? Timely maintenance is crucial to prevent accidents.

To address wiper noise, start with several aspects. First, cleaning is crucial: spray automotive glass cleaner on the windshield and wipe off oil and dust repeatedly with a soft cloth. Second, check the condition of the wiper blades—replace them immediately if cracked or deformed; if intact, clean off any dirt. Also, inspect whether the wiper arm and linkage are loose, and manually adjust and secure them. I've tried applying lubricant to the joints to reduce friction noise. When parking, avoid prolonged sun exposure to prevent rubber aging. If the issue persists, it's advisable to have a mechanic inspect the mechanical components.

Wiper friction noise indicates potential risks, which may lead to blurred vision in rainy weather. I immediately stopped to inspect the glass surface, ensuring there were no scratches or stains. Clean the wiper blades and ensure they fit properly; if the noise comes from an aging frame, replace the parts promptly. Prevention starts with daily habits, such as cleaning the glass and wipers every time you wash the car. Failure to repair may worsen the damage or even affect safe driving.
