Why does the wiper make a loud and dry sound?

[DiNorah]

When the wiper is dry and makes a loud scraping sound, it is usually caused by the aging of the wiper rubber strip, and a new wiper needs to be replaced. Most cases where the wiper squeaks and fails to clean properly are due to wear and roughness on the rubber strip, which causes abnormal noise or incomplete removal of rainwater during operation, making it difficult to see clearly while driving in the rain. Below are some daily usage precautions for wipers: 1. Maintain moisture when using the wiper: Ensure the rubber wiper strip remains adequately moist during daily use. Only with sufficient moisture can it maintain excellent flexibility and ensure tight contact with the windshield. If the windshield lacks moisture before use, dry wiping can lead to counterproductive results. 2. Wait until more raindrops accumulate on the windshield before activating the wiper: If raindrops accumulate slowly and do not obstruct vision, it is best to wait until more raindrops gather on the windshield before turning on the wiper. When using the wiper in light rain, it is advisable to spray windshield washer fluid first to ensure sufficient moisture for lubricating the wiper.

I often encounter the issue of dry and noisy windshield wipers, especially when driving, the sudden loud noise can be particularly annoying. There are several main reasons for this: the rubber of the wipers has aged, hardened, and lost elasticity; there is dust, oil film, or debris on the windshield, increasing friction; or wiping the windshield dry without using water for lubrication in dry conditions. The solutions include spraying some windshield washer fluid to moisten the glass before driving, which can reduce noise; cleaning the windshield surface with a neutral detergent to remove oil stains; and regularly checking the wipers, replacing them if cracks or hardening are noticed—a pair costs only a few dozen yuan, which isn’t expensive. After these treatments, the noise usually disappears, visibility improves, and safety risks are avoided. My experience is that simple maintenance every six months can save a lot of hassle, as comfortable driving is crucial.

As a long-time driver, I've found that squeaky and noisy wipers are mostly caused by deteriorated rubber material or contaminated glass. Aged wiper blades become stiff, resulting in less smooth wiping; when the windshield is contaminated with tree sap, insect remains, or grease, dry wiping produces squeaking sounds, affecting both mood and safe visibility. Additionally, improper installation of wiper arms or damaged springs causing uneven pressure can also lead to noise. My suggestion is to first spray windshield washer fluid for lubrication before gently wiping; for cleaning the glass, a vinegar-water solution can effectively remove contaminants; promptly replace aged wiper blades with flexible, high-quality products. A quick pre-drive check can prevent issues—it's cost-effective and practical. Don't wait until the wipers fail to clean properly before taking action, as that could cause delays. This experience has made my rainy-day driving much more reassuring—small details shouldn't be overlooked.

Loud wiper noise is usually caused by hardened rubber or a dirty windshield. When it's dry and the wiper can't move smoothly, it squeaks. I usually spray some water before driving and then wipe; if there's an oil film on the glass, clean it with detergent. Check the wiper blades if necessary, and replace them if they're worn out. Simple maintenance can reduce noise and ensure driving safety.

In my driving experience, the dry and noisy wipers are not only annoying but also pose a safety hazard. The main reasons include rubber aging and glass contaminants. If not addressed promptly, they can increase risks due to blurred vision. I regularly use glass cleaner to maintain a smooth surface and replace the wiper blades every six months to prevent hardening. I always keep windshield washer fluid in the car, moistening the blades before operation. These small habits make driving safer and are worth developing. Safety comes first—don't risk it to save money or time.

The issue of dry and noisy wipers mainly stems from dried rubber blades or contaminated glass. Cost-saving solutions include: cleaning the glass with neutral detergent to remove grease; lightly sanding slightly aged wiper blades with fine sandpaper to restore flexibility; replacing severely worn wipers (costing just tens of yuan) with new ones, which are easy to install. Avoid dry wiping—always spray water first for lubrication. This reduces noise, ensures clear visibility, extends wiper lifespan, and is both economical and effective.
