Generally speaking, the wiper life is only about one year, this is because the rubber is easy to age, so most of the wiper blades should be replaced once a year or so. Of course, if you use it more carefully, it can be about a year and a half, but it still depends on the working state of the wiper to determine whether to replace it. Generally speaking, as long as the wiper blade is not clean, the wiper blade There is no mandatory requirement for replacement time. However, under the exposure to the sun in summer and the cold in winter, the aging of the wiper blades will be accelerated, and cracking will occur. wipers.

Here are some of the reasons that can easily cause the wiper blade to age:

1. The wear of the knife edge by rainwater and air (sand, mud, dust, foreign matter);

2. Corrosion of stent coating by rainwater and cleaning liquid soaking (containing acid or alkali and other components);

3. Corrosion of the rubber strip by rainwater and cleaning liquid soaking (including acid or alkali);

4. Paraffin or automobile exhaust gas (oil); (produce jitter and pollution)

5. Cold and low temperature (snow, ice); (make the rubber strip hard and brittle)

6. High temperature (windshield, sunlight), resulting in cracking and hardening of the rubber;

7. Rubber strip damage (ultraviolet, ozone);

8. The rocker arm pressure makes the rubber strip pressurized for a long time;

9. Ultraviolet rays in the UV spectrum in sunlight, as well as temperature and humidity, cause discoloration, brightness/intensity decrease, cracking, peeling, chalking, and oxidation on the stent coating;

10. Countless round-trip cycle work, normal wear and fatigue of the rubber strip.
