What should I pay attention to when choosing wiper essence?

First of all, wiper essence, as its name implies, is used with wiper. Also known as one of the largest consumables of automobile maintenance products, it is a liquid used to clean automobile windshield. Car owners have deeply realized that the cleaning of car windshield is related to driving safety and driving vision. The function of automobile wiper essence is to remove dirt and oil stains attached to windshield. At the same time, due to its special raw materials, a protective film will be formed on the wiper rubber to protect the wiper film from drying. The essence of automobile wiper is divided into super concentrated wiper essence and traditional wiper essence.

Compared with the super concentrated wiper essence, the traditional wiper essence will do some harm to the automobile glass because of blind pursuit. The lubricant added in the super concentrated wiper essence can protect the automobile glass well, and the cost performance is also high. Next, talk about the precautions when using wiper essence. When using, we only need to open the front cover of the car, open the lid of the kettle, inject about liters of water, dilute the essence of the wiper, screw on the lid, start the car, select the button and automatically clean the windshield.

It should also be noted that the ultra-concentrated products only need to be mixed with water, usually adding water in proportion, and then no other additives are needed. At present, there are roughly two kinds of wipers. One is the traditional leisure wiper, which is generally the most common wiper. There are three or four wipers, which are adjusted by the driver according to the rain and sight. In recent years, another kind of rain bead induction type is mostly used in mid-to high-end cars. There are six points to pay attention to when choosing a good pair of wiper blades. First of all, find out what wiper blade is used in your car.

You can refer to the on-board manual to see the above wiper models. Generally speaking, wiper blades are sold together with metal poles and rarely sold separately. If you can't figure it out, ask the clerk in the parts store to help you identify it. Pay attention to whether the connection between the strut and the wiper rocker arm matches, because some arms are fixed on the rocker arm with screws, so remember to pay attention when buying. Third, pull up the wiper and touch the cleaned rubber wiper blade with your fingers to check whether it is damaged and how elastic the rubber wiper blade is.

If the wiper blade is aged, hardened and cracked, the wiper blade is unqualified. The fourth test, put the wiper switch at various speed positions, and check whether the wiper keeps a certain speed in rainy days at different speeds. Especially in the intermittent working state, we should pay attention to whether the wiper blade keeps a certain speed when moving. Fifth, check the wiper state, whether there is uneven swing or insufficient wiper.

If the following three conditions occur, the wiper blade is unqualified. The wiper swings abnormally and jumps abnormally. The contact surface between rubber and glass surface can not be completely attached, resulting in wiping residue. After wiping, the glass surface is in the state of water film, and thin strips, fog and linear residues are produced on the glass. Sixth, pay attention to whether the motor has abnormal sound during the test.
