Common problems and maintenance of automotive wipers
February 13, 2023
A good vision is an important guarantee for the normal running of a vehicle. How can we ensure a good view? Simply put, there are two conditions that cannot be reduced: 1. Adequate glassy water; 2. Normally open/closed wipers. Whether the rubber part of the wiper blade is well maintained is directly related to its working results, and the rubber has the problem of aging. The concrete manifestation is embrittlement and deformation, and embrittlement then breaks or deforms, which is the reason why the rain cannot be properly scraped. Wiper scraping leaves most of the traces of water due to the above reasons, to this end to carefully maintain the wiper rubber.
Wiper FAQ Bands Streaks: The best palm point of the wiper wall is not found, resulting in not all parts of the wiper crevice in full contact with the glass; improper arm pressure or superstructure damage, even inappropriate rain Scrapers will cause this phenomenon.
Ribbon strips
Haze marks: A layer of oily film is distributed on the windshield as the wiper is used, usually due to dirt, dirt, or glass adhered to the glass; the wiper strip is also contaminated with wax and oil. .
【Mist Streaks】
Fine water phenomenon: When the wiper is brushed through the windshield, there are still small droplets on the surface of the glass. This phenomenon is caused by the quality of the car wax, oil stains or silicide adhering to the windshield, rubber strips or strips.
[Water phenomenon]
"Kata" sound or harsh noise: When wiper irregular sweep occurs, mostly due to plastic strip wear, arm and bracket damage, aging deformation of the strip. In the absence of lubrication, the wiper will also have friction when it cleans the glass.
A good vision is an important guarantee for the normal running of the vehicle. In terms of the wiper, there are two simple conditions: 1. Adequate glass water; 2. Normally open/closed wipers.
Wiper Maintenance Do not forget the wiper Although the wiper is resting on the windshield, it is easy for people to ignore it during routine maintenance. Wiper blade maintenance method is actually very simple. In addition to washing the windows every time you wash the car, it is best to wipe the wiper strips with a glass cleaner, so that the life of the wiper strips will be longer.
[Car wash forget forget wiper]
If you do a cleaning job by the car wash shop, you can remind the clerk to do this work for you. Put the wiper switch at various speeds and check if the wiper maintains a certain speed at different speeds. There is also a check of the state of the wiper, as well as whether the wiper rod has an uneven or missing wipe. Any one of these two types of failures means that the wiper blades are damaged. In addition, pay attention to whether the wiper shakes and abnormal sound during work.
Avoid Wipers Drying Some drivers want to wipe the dust from the glass through a wiper before driving. If you want to clear the glass of dust, it is best to spray water, you can repeatedly lift the wiper to make glass water shot without scratching, when the glass is moist enough to scrape, so that it will not dry scratch the wiper rubber.
[To avoid wiper dry]
Of course, it is best to use a feather duster to remove the dust from the glass and repeat the above action. Even if the glass is moist enough, the spun yarn on the glass can damage the wiper rubber.
When using a car to pay more attention to the longer life of the wiper, it is best to avoid prolonged exposure to the sun, there is a point to pay attention to is that many owners find that there is dust on the glass, often only open the wiper to sweep sand The matter of grain, the fact that this will damage the wiper strips and the car glass, so before opening, may wish to spray a little cleaning solution. Of course, manual cleaning is better.

Maintenance wipers also pay attention to maintenance of the car's water spray system: adding neutral, decontamination, lubrication of the cleaning agent; poor cleaning fluid will corrode water spray system, wiper and car finish. Fill water in time to avoid emptying the spray motor.
It is easy to understand the problem of keeping away from oil, because oil stains on the glass can easily congeal into water droplets when it meets water. Similarly, when the car windshield or the wiper accidentally hits the oil, it will not clean the rain. Although the wiper is resting on the windshield, people can easily turn a blind eye during daily maintenance. If there is oil on the glass, it is best to use a glass cleaner to wipe the wiper strip and glass when washing.
Found oil stains on the glass, it is best to wipe the wiper strips and glass with a glass cleaner when washing.
Regular inspection This is the so-called preparation, the wiper switch is placed at various speeds during the inspection, to check whether the wiper maintains a certain speed at different speeds; Check the wiper rod for uneven or missing wipes. Any kind of failure appears to mean damage to the wiper blade. Then, start the wiper and watch if it moves smoothly. If there is a loud sound, if the sound is loud, it means that the wiper is over pressure on the glass, and proper adjustment must be made.
[Touch with a finger on the rubber sheet to see if it is damaged and the elasticity of the rubber blade]
When the squeegee sweeps one or two times, see if there is moisture left on the windshield, and at the same time observe whether or not some scratches will be left. If the scratches are clearly visible, it means the scratch on the wiper. The water strip is aging and the new strip should be replaced. Finally, check the wiper blade and use your fingers to touch it on the rubber sheet to see if there is any damage and the elasticity of the rubber blade. If the blade is aged, hardened and cracked, it should be replaced in time.
In the event that the wiper cannot be used normally, the key is to replace the rubber strip on the wiper blade. For too long time, rubber strips are aged, worn or cracked. Especially when there is dirt, the performance of the wiper will be further reduced because the dirt is trapped between the rubber strip and the glass.
