Squeaky windshield wipers are more than just a nuisance. They can reduce visibility during rain and, in some cases, scratch your windshield if the blades are damaged. You can fix this issue quickly by following these simple steps.
Step 1: Clean Everything Thoroughly
Use a glass cleaner and a microfiber cloth to wipe both the windshield and the wiper blades. Pay close attention to the rubber edge that makes contact with the glass. Dirt and residue are common causes of squeaking.
Step 2: Inspect for Damage
Check the rubber for cracks, stiffness, or tears. If the blades are visibly worn or the rubber feels hard, replace them. Cleaning will not restore damaged blades.
Step 3: Apply Rubbing Alcohol
Dampen a soft cloth with isopropyl alcohol and run it along the length of each blade. This helps remove built-up grime and can soften the rubber for smoother operation.
Step 4: Check Proper Contact
Make sure the wipers sit evenly on the windshield. Uneven pressure can cause noise and leave streaks. Adjust the wiper arms if they appear misaligned.
Step 5: Consider Silicone Treatment
If squeaking continues, apply a silicone-based wiper conditioner. It reduces friction and helps the blades glide more smoothly. Repeat this maintenance monthly, especially after harsh weather, to keep your wipers performing at their best.
