Replacement inspection of car wiper

Some people will find that the car wiper that they just changed doesn't last long, and it doesn't wipe cleanly, and they don't know whether they need to be replaced. Let us briefly introduce this issue below.

    The methods to determine whether the car wiper needs to be replaced are:

1. Pull up the wiper wiper on the car and touch it with your fingers on the wiper rubber after cleaning to check whether there is damage and the elasticity of the rubber blade. If the blade is aging, hardened and cracked, it needs to be replaced;

2. Some people have this feeling. When it rains heavily, the car wiper feels good, but when it rains lightly, you will find that the wiper will leave uneven marks on the glass surface, which will affect the car. The view of the windshield also shows that the wiper you use has hardened and needs to be replaced in time;

    3. When the tension of the wiper arm spring becomes weak, the wiper arm needs to be replaced. Because the wiper blade is in close contact with the windshield by the force of the wiper arm spring, when the tension of the spring becomes weak, it will bring strong wind pressure to the windshield due to the high-speed driving of the car, which will cause the wiper to float, causing some The glass has not been swept, in this case we recommend replacing the wiper arm as soon as possible;

 4. If the surface of the windshield when the wiper is working is foggy, fine water droplets, streaks or partial blur, this is affected by oil film, dirt or car wax, and there is no need to replace the wiper. Just clean the windshield and wiper blades. If the wiper has local aging or small-scale wear, you can use No. 2000 sandpaper to polish the wiper. Because the wiper itself has a certain thickness, it can still be used normally after polishing off a thin layer. But when polishing, it must be noted that the polishing of the entire wiper blade must be even. Generally, the replacement cycle of car wipers is about six months to one year.
