What causes the squeaking sound when wiper blades scrape the windshield?

The reasons for the squeaking sound when wiper blades scrape the windshield are: 1. Wiper blade aging. Wiper blades are rubber products that can harden and deteriorate over time. In this case, the wiper blades need to be replaced. Generally, wiper blades should be replaced every 1 to 2 years; 2. There are foreign objects (such as oil film) between the wiper blade and the windshield, causing friction and resulting in noise when the wiper operates; 3. Issues with the linkage mechanism, usually caused by continuous or improper use, leading to deformation or rust, which in turn causes noise. During normal use, avoid prolonged or continuous operation of the wipers. It's best to have a few seconds' interval between uses.

I've been driving for over 20 years, and the squeaking sound when wipers scrape the windshield is usually caused by hardened rubber blades due to aging or dirt/grease on the glass surface. Last summer I encountered a similar issue - dry weather made the friction noise worse, but replacing the wiper blades solved it. If there are insect remains or wax residue on the glass, try cleaning with dish soap solution followed by rinsing. Loose wiper arm installation or uneven pressure can also cause noise; gently adjusting the arm might help. Check wiper blade wear every six months - don't wait until rainy days when visibility suffers, as this poses driving risks. Overall, prevention beats repair - regular maintenance saves hassle.

I often DIY car repairs myself. If the wipers make a squeaking noise, it's mostly due to worn wiper blades with uneven edges or a dirty windshield. I would first try thoroughly cleaning the glass with a mixture of white vinegar and water to remove any oil film. If the noise persists, remove the wiper blades to check if the rubber is cracked or deformed; if aged, simply replace them—it's an easy operation, just buy compatible models online and install them in minutes. Also, check if the wiper arm connection is loose and needs tightening. A reminder: avoid wiping on a dry windshield to prevent increased friction, and use mild detergents when cleaning. Addressing the issue early can prevent glass scratches that impair visibility and safety, saving on later repair costs.

I just started driving, and the squeaking sound of the wipers makes me nervous—there might be a problem. A friend said common causes are old wiper blades becoming stiff or dust stuck on the windshield. If cleaning the glass doesn’t help, the parts might be damaged, so it’s best to visit a professional shop for inspection to avoid driving hazards in rainy weather and extend the parts' lifespan. A simple self-check is to see if the glass has obvious dirt and wipe it yourself. The key is not to delay handling it—prioritize safety first to reduce accident risks.
