What to Do When the Car Windshield Is Dirty and Can't Be Wiped Clean?

[DeMadelyn]

Reasons and solutions for a dirty car windshield that can't be wiped clean are as follows: Using dish soap and toothpaste for cleaning: First, wet the glass with water, apply toothpaste to the left half, scrub the windshield with a sponge, and then rinse it clean with water. Dirty wiper blades: If the rubber strips on the wiper blades are loosely attached, they won't clean effectively. If you find the wiper blades are loose, you can use needle-nose pliers to tighten the gaps at each joint and the rubber strips. This not only effectively reduces noise but also improves the wiping performance of the wiper blades.
