When Should Wiper Blades Be Replaced?

[AlexanderRose]

Wiper blades replacement time is not fixed, as it varies depending on the quality of the wiper blades, usage environment, and maintenance level. The key indicator is whether the wiper blades clean effectively and if there are water streaks during use. After prolonged exposure to sunlight and rain, the wiper blades may become fatigued, resulting in ineffective cleaning. Wiper blades are strip-shaped structures installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Their primary function is to clear rain, snow, and dust from the windshield that obstruct the view.

When to replace wiper blades depends on actual usage. If after wiping, the windshield still has water marks or streaks, or makes squeaky noises during rainy days, it's time for a replacement. Aged rubber material can't clean properly, impairing nighttime visibility and posing dangers. I usually inspect them every six months and replace them before the rainy season to ensure clear vision. Safety comes first—don't wait for an accident to regret it. Many brands now offer more durable wipers, such as silicone ones that last longer, but regular maintenance is still needed. Avoid direct sunlight to prevent the rubber from hardening.
