Striation: the best supporting point of the wiper wall was not found, which led to the wiper dogma that not every part was in full contact with the glass; Improper arm pressure or superstructure damage, and even improper wiper blade will lead to this phenomenon.

Foggy streaks: With the use of wiper, an oil film is distributed on the windshield, which is usually caused by dust, dirt or car wax adhering to the glass; Wiper strips are also polluted by car wax and oil pollution.

Fine water phenomenon: when the wiper brushes the windshield, there are still small water droplets sticking to the glass surface. This phenomenon is caused by the adhesion of car wax, oil stain or silicide to windshield, adhesive tape or the quality problem of adhesive tape itself.

Harsh noise: when the wiper scratches irregularly, it is mostly caused by rubber strip wear, arm frame damage and rubber strip aging and deformation.

Cracking of adhesive tape: The use of adhesive tape has a certain life. Under the destruction of cold, heat, acid and alkali, hardening, cracking or peeling are inevitable. Some wiper blades will fall off directly from the wiper arm. If the quality of the adhesive tape is not good, the damage time will be faster.

Scaling of adhesive tape: Most of the reasons are that the oil stains accumulated on the wiper for a long time and the adhesion of car wax will produce a gap between the wiper and the windshield, which cannot be completely wiped. When the above situation happens to the wiper and cannot be solved in time, your wiper will further deteriorate, seriously affecting driving safety.
