Why Doesn't the Wiper Clean Properly?

Reasons why the wiper doesn't clean properly: 1. Wiper blade aging or hardening; 2. Foreign objects stuck between the wiper blade and windshield; 3. Dirty windshield with oil film; 4. Incorrect wiper arm angle; 5. Improper use of the wiper. Solutions for an unclean wiper: 1. Rotate the entire wiper bracket 180 degrees; 2. Adjust the pressure of the wiper arm on the glass by bending the arm manually. Precautions for wiper use: 1. Regularly add windshield washer fluid, do not use tap water as a substitute; 2. Ensure the wiper is used only when there is water on the glass surface; 3. Clean the wiper blade rubber and any debris on the glass surface promptly; 4. Lift the wiper arm when the vehicle is parked for an extended period or in snowy/icy weather.

I often encounter the problem of wipers not cleaning properly while driving. The most common reason is aging wiper rubber—over time, the rubber hardens and cracks, making it impossible to wipe away rainwater. Another issue is oil film on the windshield, caused by roadside dust or exhaust deposits, which requires specialized cleaning agents to remove. I’ve experienced this myself, and replacing the wiper blades usually solves the problem—you can get a new set for just a few dozen yuan on Taobao. Additionally, if you use the wipers on a dry windshield, it can accelerate wear on the glass surface. I recommend regularly cleaning the windshield with dish soap and water to keep it clear. If that doesn’t help, you should check whether the wiper arm is loose or if the wiper motor lacks sufficient force—it’s best to have a professional mechanic inspect these issues. Safety is paramount, especially during heavy rain when poor visibility can easily lead to accidents. I always remind my friends to replace their wipers every six months—it’s not worth skimping on.

As an experienced driver, I've found that wipers not cleaning properly is mostly due to insufficient arm strength or mechanical issues. For example, loose or rusted wiper linkage can cause the blade to not adhere tightly. Also, weak wiper motor output can't keep up with speed in winter or heavy rain. This is very dangerous - poor visibility in low light increases braking distance and easily causes rear-end collisions. I recommend stopping immediately to check, and adjusting the wiper arm angle before replacing wipers. If you often park roadside in direct sunlight, high temperatures will accelerate rubber deformation. Additionally, don't use tap water as washer fluid - it leaves water stains and clogs nozzles. Regularly clean glass edges with alcohol to remove dirt, and avoid dry wiping in sandy conditions. During every maintenance, I have mechanics test voltage to ensure system stability.

I think the wipers not cleaning properly might be due to dirt accumulation or improper installation. The windshield often has insect remains and dust, forming obstacles that cause streaks. The wiper blade angle not being adjusted properly can also lead to uneven wiping. I've tried simple methods: wiping the glass with a cloth to remove grease; or soaking the wiper blades in vinegar water to restore elasticity. Avoid leaving them under direct sunlight for long periods, as it can damage the rubber. Try adjusting the tension of the wiper arm. If the effect is poor, it might be due to a clogged system—check if the washer fluid reservoir is full. Clean the spray nozzles to prevent water residue. Timely maintenance ensures safer driving.

From a safety observation perspective, unclean windshield wipers can severely impair driving visibility, especially at night or during heavy rain. The primary cause is thick oil film buildup on the windshield from road grease, which the wipers struggle to remove. Deformed or aged wiper blades may also leave water streaks, increasing accident risks. Professional degreasing sprays or wiper cleaning solutions are recommended. Additionally, low voltage in the wiper motor may cause uneven movement. Timely maintenance and regular inspection/replacement of wipers are crucial to ensure clear road visibility during harsh weather conditions - a key factor in maintaining emergency response capability.

I've noticed seasonal impacts: freezing temperatures in winter harden wiper rubber, leading to poor cleaning; summer heat and dust cause rapid oil film buildup. The reason is temperature changes causing wipers to contract or expand, losing elasticity. Windshields develop micro-cracks from sun exposure, trapping dirt. I recommend replacing wipers before rainy seasons and adding antifreeze washer fluid to prevent winter failures. When weather warms up, thoroughly clean glass surfaces to reduce dust accumulation. Also, check if wiper arm springs are fatigued - if rebound is weak, they need adjustment or replacement. Proper system maintenance extends lifespan and improves driving experience.
