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.
