What Are the Causes of Wiper Blade Noise?

[DiCassandra]

There are three main reasons for wiper blades making abnormal noises. Below is a detailed explanation of these three causes: 1. Wiper blade aging: Wiper blades are made of rubber, and prolonged exposure to sunlight, wind, and rain can easily lead to aging. Generally, the lifespan of wiper blades is about one to two years. When wiper blades age, they should be replaced promptly. 2. Foreign objects between the wiper blade and windshield: It is relatively common for foreign objects, such as small stones or debris, to get stuck between the wiper blade and windshield. This not only causes noise but can also scratch the windshield. It is important to promptly remove any foreign objects between the wiper blade and windshield. 3. Wiper motor damage: If the wiper motor is damaged, professional repair personnel should be hired for inspection and repairs.

The wiper makes strange noises, which I've encountered several times while driving. That rainy day, the scraping sound was creaking on the road, making me nervous. The main reason is that the wiper rubber blade has aged. Over time, it hardens, causing excessive friction against the glass, resulting in loud noises. Additionally, oil film or dust on the glass surface, such as accumulated grease or rainwater marks, can make the wiper slip and produce sounds. Moreover, improper installation of the wiper arm, like an angle that's too steep or too loose, can also easily cause noise. In such cases, I first spray windshield washer fluid on the glass and wipe off the oil film with a soft cloth. If there's no improvement, it's time to replace the wiper blades—silicone ones are more durable. It's important to regularly check the wipers before the rainy season; don't wait until they fail on the road and cause delays. Safe driving comes first—this is something I've learned from experience.

As a car enthusiast, I enjoy maintaining my vehicle myself and have researched the issue of wiper noise multiple times. The core problem lies in worn or deformed wiper blades, where the rubber becomes too dry and hardened, causing squeaking when dragging across the glass. Contaminants like oil or dust coatings on the glass surface can also interfere with wiping, leading to noise. Additionally, overly tight wiper linkages or motors, or using the wipers directly when dry can exacerbate the noise. I recommend replacing wiper blades every six months, opting for quality brand products. Regularly clean the windshield with washer fluid weekly to prevent oil film buildup, and after cleaning, don't forget to check if the wiper arms have proper tension. Even minor wiper noise can affect driving mood, so addressing it quickly saves costly repairs later. Don't wait until rainy days when poor visibility makes you regret delaying the fix.

I remember when I was young, the sound of windshield wipers was a common occurrence, as the parts on old cars were quite poor. The root cause of wiper noise often lies in the aging and cracking of the wiper rubber blades, or residues like bird droppings and dust on the windshield, which cause friction and noise when wiping. If the wiper arm is not adjusted correctly, such as being too close to the edge or unbalanced, it can also squeak. Nowadays, there are better products available. I usually opt for low-temperature-resistant wiper blades to deal with winter icing issues, or simply use a vinegar-water solution to spray and clean oil stains off the windshield. Replacing parts early to prevent noise ensures safe driving and peace of mind—don’t wait until a rainy day to scramble for solutions.
