When is the appropriate time to replace the wiper blade

     When is the appropriate time to replace the wiper, we need to make a judgment. First of all, if you can see the symptoms of damage from the naked eye, such as cracks, rust, and deformation, and you can feel the hardening of his rubber with the touch of your fingers, it means that the rain The scraper has reached the point where it really needs to be replaced.

       If these symptoms cannot be observed from the wiper blade itself, the windshield can be used to determine whether there is a problem with the wiper. Whether there are slender marks on the glass, whether it is difficult to see the outside world after being cleaned, if there are these problems, it may be that there is abrasion or foreign matter on the wiper blade. To clean the edge of the wiper blade, if the symptoms are still not eliminated, it proves that it needs to be replaced.
