What are the reasons why the wiper does not clean the glass

Wiper, also known as wiper, water dial, wiper or windshield wiper, is a device used to wipe off the raindrops and dust attached to the windshield of the vehicle to improve the driver's visibility and increase driving safety. Cars almost everywhere have wipers because of legal requirements. Vehicles such as hatchbacks and SUVs also have wipers on the rear windows. In addition to cars, other means of transport are also equipped with wipers, such as trains, trams, etc. Some engineering equipment, such as cranes, are also equipped with wipers. What are the common reasons for the wiper not to clean the glass?

1. The glass is not clean

Usually car washes do not clean the glass properly, and the surface of the glass adheres to fine tar particles, etc., which will reduce the surface finish of the glass. The rough glass surface will not only be unclean, but will also damage the wiper strip.

2. Rough wiper strip

If the original wiper strip is properly maintained, its lifespan can reach 5 years. It should be noted that the fine sand particles on the wiper strip should be removed in time. Wiping with these fine grains of sand is equivalent to sanding the wiper blade with a grinding wheel. It doesn't take long for the finish to drop, and the frizzy strips won't scratch the rain.

If it is found that the wiper is not clean, most of it is due to improper maintenance. The reason for the roughness of the wiper rubber strip is just to find a way to make the rough rubber strip smooth and clean. So, how do you get your wipers back like new?

1. First remove the two wipers

Generally speaking, for ordinary type wipers, by turning off the flame after resetting, when the car stops running, manually pick up the wiper, and then take it out in the opposite direction. The method is also a technique for removing the wiper.

2. Prepare a piece of water sandpaper

Buy a piece of water sandpaper, tear the water sandpaper into small pieces, and use a small piece at a time.

3. Soak the wiper and water sandpaper with clean water

Fill a suitable container with water and soak the wiper blades and water sandpaper in the water.

4. Sand the wiper strip with water sandpaper

Note that the strip is like a knife, you not only need to sand the two sides, but also the front of the strip properly. It doesn't have to be very long, about 5 minutes will do.
