What to Do When Wiper Blades Don't Clean Properly?
2 Answers
Here are the reasons why wiper blades don't clean properly: 1. Dirty windshield: Inadequate cleaning of the windshield during regular car washes can leave sticky particles on the glass, preventing the wiper from cleaning effectively and potentially damaging it. The solution is to visit a car wash for a thorough windshield cleaning. 2. Hardened wiper blades: Aging wiper blades can harden. You can replace them with new ones or clean the wiper with a lubricant. 3. Misaligned wiper arm: Adjust the angle of the wiper arm. Use an adjustment wrench to hold the wiper and gently rotate it to align it properly, or seek professional help at a repair shop. 4. Frozen wiper blades: Wiper blades, usually made of rubber, can freeze and harden in cold winter temperatures. After starting the car, direct some warm air to the windshield to raise its temperature slightly before using the wipers.
I've been driving a ride-hailing car for over a decade, and having windshield wipers that don't clean properly is a common occurrence. Just the other day, it suddenly started raining while I had passengers, and the wipers left streaks of water everywhere, making it almost impossible to see the road clearly. I pulled over and noticed that the rubber blades were cracked. Rubber parts can age and deform when exposed to direct sunlight, especially during the scorching summer heat. My advice is to lift the wipers when parking to avoid direct sun exposure and regularly clean the rubber blades with a damp cloth to remove grit. I always keep a spare set of wipers in my car—they cost about thirty yuan a pair and are easy to replace yourself. If there's an oily film on the windshield, mix dish soap with water and give it a good scrub. If the film is too stubborn, you’ll need a professional glass cleaner. Remember to spray windshield fluid to lubricate the wipers before each use in the rain—it helps extend their lifespan.
