What are the reasons for wipers not cleaning properly?

Analysis of reasons why wipers do not clean properly: 1. Wiper blade issues: Wiper blades are made of rubber and will harden and age over time, especially in winter. This not only causes noise but also affects cleaning performance. 2. Debris between the wiper blade and windshield: If you hear a sharp friction sound when using the wipers, check and remove any debris stuck between the wiper blade and windshield to ensure smooth operation. 3. Dirty windshield: If the wipers are not the problem, there may be an oil film on the windshield. 4. Incorrect wiper arm angle: If the wipers aren't cleaning properly due to angle issues, try adjusting them. If that doesn't work, the wiper may be applying too much pressure—simply loosen the spring tension. 5. Incorrect wiper usage: Using wipers on a dirty windshield without spraying water can damage the blades and scratch the glass. Avoid parking your car in direct sunlight, as prolonged exposure can accelerate rubber wiper aging.

I've encountered the issue of wipers not cleaning properly several times. The main reason is the aging or deformation of the rubber on the wiper blades. Over time, the rubber hardens or cracks, making it unable to sweep away rainwater effectively. Additionally, oil film, dust, or insect residue on the windshield can cause the wipers to fail, especially noticeable during rainy days when oil stains become more apparent. It's also common for the wiper arm's spring to weaken or get stuck, preventing the blade from pressing firmly against the glass. Using the wrong windshield washer fluid or too little of it can also affect cleaning performance. Before driving, I usually wipe the glass with a towel and regularly check the condition of the wiper blades. Replacing them every six months can help avoid this problem. Don't underestimate the importance of clean wipers—blurred vision can easily lead to accidents. A quick check before driving saves a lot of trouble.

After decades of driving, I've found that wipers not cleaning properly are mostly caused by aging or dirty rubber blades. Wiper blades tend to harden and deform after two or three years of use, resulting in incomplete water removal. The situation worsens if the windshield has oil stains or bird droppings residue. Improper installation of wiper arms causing uneven pressure is also common, or springs may fatigue and lose rebound force. High concentration of washer fluid leaving excessive residue can also cause streaks. I recommend replacing wiper blades before rainy seasons and cleaning the windshield with neutral detergent spray and wiping, preventing mud accumulation. Though seemingly minor, unclean wipers can lead to misjudgment in heavy rain when road visibility is poor. Developing regular maintenance habits makes driving much safer.

For car enthusiasts, wiper blades not cleaning effectively may be due to worn or uneven rubber on the wiper blades, which lose elasticity over time and fail to sweep water properly. Oil film or stains on the windshield can affect adhesion—wiping with a degreaser after washing the car can help. Loose wiper arms or incorrect angles may cause uneven wiping and require adjustment. Using inappropriate windshield washer fluid can leave streaks. Preventive maintenance is crucial; inspect the rubber blades every season and replace them promptly to ensure clear visibility. Don’t wait until rainy days to regret neglecting them.

It's really frustrating when the wipers don't clean properly while driving mom's car to pick up the kids. The most common issue is the rubber blades becoming brittle and deformed after prolonged use, or oil and dust on the windshield preventing a clean sweep. Unstable wiper arm fixation or uneven pressure is also a frequent problem, or light rain failing to wash away dirt. I think it's best to check the wiper blades' condition when seasons change, wiping the windshield and wipers with a soft cloth to ensure they're clean and free of residue. Don't forget to add an appropriate amount of cleaning solution when washing the car for better anti-fouling effect. Driving safety comes first—poor visibility can easily lead to accidents, so early maintenance saves trouble and hassle.

Streaky wiper blades often indicate aged rubber losing elasticity, or oil stains/insect residue on the windshield affecting contact. Bent wiper arms or incorrect installation angles also cause streaks. Improper washer fluid leaving dirt worsens it. This poses major hazards in rain - reduced visibility increases rear-end collision risks. Routinely check rubber wear before driving, replace blades periodically, and polish glass with professional cleaners. Developing these habits ensures driving safety - never compromise safety over minor issues.
