What Causes Loud Wiper Noise?

[DiDawson]

When the wiper blades scrape loudly and feel dry, it is usually caused by aging rubber strips, requiring replacement of new wiper blades. Most cases of squeaky wipers with poor cleaning performance result from worn and roughened rubber strips, which generate abnormal noises during operation or fail to completely remove rainwater, making it difficult to see clearly while driving in rainy weather. Below are precautions for daily wiper usage: 1. Maintain proper moisture when using wipers daily: Ensure the rubber wiper strips retain adequate moisture during regular use. Only with sufficient moisture can they maintain excellent flexibility and tight contact with the windshield. Insufficient moisture on the windshield during dry wiping may produce counterproductive results. 2. Wait until more raindrops accumulate before activating wipers: If raindrops accumulate slowly without obstructing visibility, it's best to delay wiper activation until more droplets gather. When using wipers in light rain, always spray windshield washer fluid first to ensure adequate moisture for lubricating the wiper blades.
