Why Your Windshield Wipers Squeak and How to Stop It

Squeaky wipers are hard to ignore. It’s annoying to listen to while driving, and it can also potentially ruin your windshield. A noisy wiper can also increase your risk of accidents as you get distracted by the sound. But why is it squeaking in the first place? Below, I discussed the common reasons why and what you can do about it.

Why windshields wipers squeak

If your wipers are getting squeaky, the following might be the reasons why:

Improper installation

Windshield wipers that are not installed properly will be noisy during operation. Nowadays, you can easily find stores that offer wiper installation at a dirt-cheap cost. While this will save you money, the installation is likely subpar. Over time, your wipers will produce all sorts of noise.

This is the reason why you should only trust professional technicians in installing windshield wipers. If the squeaking isn’t going away after cleaning, you should bring your vehicle to a car technician instead.

Accumulated dirt

Road debris can accumulate on your windshield wipers. Once you turn it on, you’ll notice a scratchy or squeaking sound. Worse, the contaminants will scrape your windshield, which will leave ugly scratches.

When cleaning your wipers, you should avoid petroleum-based cleaners as this will shorten the lifespan of the rubber material.

Old wipers

Windshield wipers aren’t meant to last forever. At some point, the rubber will suffer from wear and tear where it will require a replacement.

As the rubber wiper material crumbles, it will start to scratch the windshield. This will produce a squeaking noise. In the long run, the hardened rubber will cause damages to your auto glass.

Manufacturing defect

It’s not enough that you replace your wipers, you should also get one with reliable quality. Substandard wipers will still squeak even if it’s installed correctly. You need to replace this, or your windshield will bear the brunt of the damages.

It’s also important to check the condition of the wiper before installing it. Some wipers may have been stored for too long that the rubber materials are already hardening.

How to stop your wipers from squeaking

To put an end to your windshield wiper’s squeaking, you can do the following:

  • Clean it regularly. It’s important to remove dirt deposits on the wiper blades. You should do this once a week or more frequently if you keep going for long drives.
  • Refill your wiper fluid. Lack of moisture will create friction between the wiper blades and the windshield glass. You should top up your wiper fluid once it’s running low.
  • Replace the blades. If your wipers keep on squeaking after doing the first steps, replacement is the best solution.
  • Check the windshield. A faulty windshield can make your wipers squeak even if the latter is properly installed. Your windshield might be covered with scratches and cracks that create the noise as the wipers glide through it.

Conclusion

Squeaky windshield wipers are easy to fix. Inspecting and cleaning your wipers will help prevent the noise from distracting you as you drive. A local car detailer can also help in resolving the issue.
