What to Do When Windshield Wipers Don't Clean Properly?

[LaBrandon]

Here are the explanations for windshield wipers not cleaning properly: 1. The reason why windshield wipers don't clean properly is that there are stains on the glass that haven't been cleaned, which can cause the wipers to develop burrs over time; 2. There are two methods to deal with stains: sandpaper polishing the wipers and using toothpaste. Here are some extended tips for maintaining windshield wipers: 1. Keep the wipers in the lowest position when not in use: When not using the wipers, place them in the lowest position and pay attention to cleaning the lower part of the wipers to prevent foreign objects from causing long-term pressure on the wiper blades, leading to deformation; 2. It's best to use wipers only for cleaning rainwater: Avoid using wipers to clean dust or stains on the windshield under normal circumstances. The primary function of wipers is to clean rainwater, and unknown stains on the glass may cause the rubber blade edges to age or wear, reducing the wipers' lifespan; 3. Clean once every one or two weeks: Lift the wiper blades and separate them from the windshield to check for any damage. Replace them promptly if damaged. If there's no damage, soak the wiper blades in water and polish them several times with water sandpaper, then rinse with clean water.
