Spring rain increases, rain driving, for car owners, the field of vision is very affected, if at this time if the wiper is not clean, it is very dangerous! Why does a good wiper not scrape clean? Today, I will take the riders to explore the reasons for this.
1. Wiper adhesive strip aging
Wiper tape is a rubber product, after years of wind and sun, the rubber will lose its softness, aging and hardening, not only affect the cleaning effect, but also may emit different degrees of abnormal noise, then it is necessary to replace the rubber strip in time.
Generally speaking, the wiper is used for about 1-2 years, and the longest use is 3 years.
2, wiper spring does not give force
After a long period of use of the wiper, the upper spring will appear metal fatigue, making the wiper loose and weak during work, unable to closely grasp the windshield to scrape the glass clean. Try clamping the wiper with a wrench and gently twisting it to adjust the spring to a vertical state.
3. Empty scraping brush
Sometimes we manually scrape the glass, the first is easy to only move the wiper without spraying glass water, and the wiper is most afraid of no water dry scraper, this kind of empty scraper very much affects the service life of the wiper. Therefore, no matter when the wiper is used, it is necessary to open the glass water edge to flush and brush to avoid "dry brushing" affecting the service life of the wiper.
4. "Oil film" on glass
The windshield of some cars always feels oily, and some will appear like rainbows of different shades of color, which is the glass oil film. When the car is driven for a long time, there will be small holes in the windshield, coupled with the small dirty things outside entering it, after a long period of accumulation will form a glass oil film. This oil film can not be cleaned by the wiper, and can only be washed with a special oil film cleaning agent.
So, how do you keep your wiper clean?
· Clean up foreign objects between the front windshield in a timely manner
When a sharp friction sound occurs when the wiper is turned on, the wiper should be inspected. Regular cleaning of the car windshield to prevent stuck foreign objects, protect the wiper, can achieve the purpose of prolonging the service life of the wiper.
· Aging parts are replaced in time
If it is only the spring loose, you can adjust it by hand. However, the "life" of the spring is irreversible, and the wiper is found to be aging and rusting the spring, and it is directly removed and replaced with a new one.
· Replenish glass water in time
Ensure that the wiper blade is used if there is water on the surface of the windshield and avoid dry wiper blades. Do not use "tap water + dish soap" instead of glass water, because the water quality of tap water is hard, which contains a large number of calcium and magnesium ions, long-term use, will leave this relatively large scale in glass kettles, pipes, water sprays, these scales will block the water spray, easy to cause metal parts rust. Try to choose high-quality automotive glass cleaning water, which can effectively clean a variety of stains and reduce the damage to the wiper strip.
· Remove the oil film regularly
At present, there are already many glass degreasing film products on the market, both products that can clean the glass directly degreasing film, and products that can be added to the glass water for mixed use, or more convenient.
