Why are My Windshield Wipers Rubbing? (Causes & Fixes)

If you’re wondering, Why are My Windshield Wipers Rubbing, it’s important to check a few things. Look at how clean your wipers and windshield are, and make sure the wipers are straight and working right. Understanding these can help fix the rubbing problem.

Why are My Windshield Wipers Rubbing?

Rubbing windshield wipers can be a source of annoyance and hinder visibility. Based on our experience, this issue usually stems from a few common factors.

Debris Buildup

We often find that accumulated dirt, grime, and other residues like tree sap or insects on the blades or windshield are the main culprits. Regular cleaning of both the windshield and wiper blades is crucial to prevent this friction and rubbing.

Wax Residue

If you’ve recently waxed your car and the windshield wasn’t properly buffed, the waxy film can cause the wipers to catch and rub. Ensuring thorough cleaning post-waxing can avoid this problem.

Worn-Out Blades

Blades that have hardened or lost flexibility over time tend to make uneven contact with the glass, leading to rubbing. We recommend inspecting and replacing wiper blades annually or when signs of wear appear.

Misalignment and Sizing

Improperly installed or damaged wiper arms can misalign the blades, and using incorrect blade sizes can also cause issues. It’s important to ensure the blades are the right size for your windshield and correctly installed.

Loose Wiper Arm Nuts

Occasionally, loose nuts that hold the wiper arms can lead to wobbling and rubbing. Tightening these nuts can be a simple and effective fix.

Damaged Linkage

Over time, the linkage system connecting the blades to the motor can become rusty or bent. This can hinder the smooth movement of the blades. Checking and repairing any damage to the linkage can restore proper function.

How to Stop Windshield Wipers from Rubbing?

Stopping your windshield wipers from rubbing involves addressing the root cause of the issue. Regular preventive maintenance can significantly reduce your likelihood of windshield wiper rubbing, ensuring your smooth operation and clear visibility.

Here are some effective solutions based on our experience in dealing with windshield wiper rubbing problems.

Regular Blade Inspection and Replacement

Inspect your wiper blades periodically for signs of wear, such as cracks or splits in your rubber. It’s recommended to replace your wiper blades every 6 to 12 months, depending on your usage and environmental conditions.

Clean Wipers and Windshield Regularly

Dirt and debris on your windshield or wiper blades can cause friction and rubbing. Clean your windshield often and wipe down your wiper blades with a damp cloth to remove any of your dirt or grime.

Properly Align Wiper Arms

Ensure that your wiper arms are properly aligned and tensioned. Misaligned or loose wiper arms can cause your blades to hit your windshield improperly.

Use Windshield Treatments

Applying your water-repellent treatment to your windshield can improve the glide of your wiper blades, reducing friction and your likelihood of rubbing.

Avoid Ice and Snow Build-up

In winter, clear ice and snow from your windshield before using your wipers to prevent blade damage and ensure your smooth operation.

Regular Vehicle Check-ups

Include your wiper inspection in your regular vehicle maintenance. A professional can spot and correct issues with your wiper alignment, motor function, or other mechanical problems.
