Toyota Corolla Windshield Wipers Leaving Streaks – Help?

Hi!

If cleaning the wipers and windshield hasnt fixed the streaking issue, here are a few potential causes and solutions:

Worn o r Damaged Wiper Blades: Even if they don’t look damaged, wiper blades can wear down over time, especially if they are older. The rubber can harden o r crack, which leads to poor contact with the windshield and causes streaks. Consider replacing the wiper blades, even if they appear to be in good condition.

Wiper Blade Build-Up: Sometimes, dirt, grease, o r old washer fluid residue can build up on the wiper blades, leading to streaking. Try cleaning the rubber part of the wiper blades with a cloth soaked in rubbing alcohol to remove any built-up grime.

Windshield Cleanliness: Streaks can also be caused by residue on the windshield itself, even after it looks clean. Make sure youre using a quality glass cleaner, and consider wiping down the windshield with a clean microfiber cloth after spraying the cleaner. You can also try using a mixture of water and vinegar 50/50 for a deep clean.

Washer Fluid: Sometimes, the type of washer fluid youre using can leave streaks. If the fluid is old o r too thick, it could be leaving a residue. Try using a different washer fluid o r make sure it’s fresh and not contaminated.

Wiper Arm Pressure: If the wiper arms aren’t applying enough pressure to the windshield, they won’t wipe effectively. This could be due to worn-out springs o r improperly adjusted arms. If you notice that the wipers are leaving streaks in certain areas but not others, this might be the issue.

Rain-X o r Other Coatings: If you’ve applied a water-repellent treatment like Rain-X to the windshield, it can sometimes cause streaks if the wipers aren’t in great condition. The coating makes it harder for wipers to get a clean swipe. You can try removing the Rain-X coating with a dedicated cleaner and then see if it improves.

Hopefully, one of these solutions helps! Let me know if you need further assistance.
