Why is the windshield wiper not cleaning water properly?

[MacJulianna]

The reasons why the windshield wiper does not clean properly: 1. Wiper angle: The angle of the wiper can cause it to not clean properly, and it only needs to be adjusted. If the downward pressure of the wiper is too strong, it will inevitably lead to uneven force distribution, and at this point, the distance between the springs needs to be relaxed. 2. Foreign objects on the wiper: When you hear a "squeaking" noise while the wiper is operating, it is likely due to foreign objects between the wiper blade and the windshield, which can also cause the wiper to not clean properly. At this point, you need to check if there are indeed foreign objects, and if so, they must be cleaned. Of course, it could also be because the wiper blade is too rough, in which case it only needs to be smoothed with sandpaper. 3. Wiper hardening: After all, everything has its own service life, especially vehicles frequently parked on the street, which are inevitably exposed to sun and rain. Over time, this will certainly accelerate the aging of the wiper rubber, so the wiping effect naturally becomes less obvious, and at this point, a new wiper should be replaced as soon as possible.
