Spring has arrived, and the rains will increase , denefitily the wipers will have more responsibility. The lifetime of the wiper blade is about 1 year. If the weather is exactly bad, the life will be shortened. Although the wiper blade is small, it is related to our safety. About 90% of traffic accidents in rainy days are related to the wiper blade.
The following are frequent questions and solutions:
1. Filamentous streak. There are thin streak on the windshield when wiping. This situation is generally caused by dust, leaves, bird droppings and other fixed particles on the windshield or the wiper rubber refill strip after the wiper is used for a period of time , it appears thin streak during the wiping; Solutions: Lift the wiper up and clean the windshield and wiper back with soft towel.
2. The windshield is foggy and comes with streak; This situation is due to the influence of oil film (paint protective film), dirt or car wax on the windshield. The solution is to clean the windshield and wiper.
3. Water drops. When the windshield wiper wipes over the windshield, some small water drops still adhere to the surface of the windshield. This situation is caused by car wax, coating (paint protective film), or silicide adhere to the windshield. Keep the windshield clean; In addition, if the rubber refill strip get hardening or aging may also cause water drops, it is generally recommended to replace the new wiper;
4.The middle part ceases to adhere to the windshield, causing in unclean wiping effect , and it appears large traces;This situation is generally caused by the light pressure of the wiper arm.Firstly please go to check whether the wiper arm is loose. If it is loose, adjust the spring pressure of the wiper arm to return to the normal value; But some old models' wiper arm are used for a long time, which cause insufficient pressure, if the wiper arm pressure is adjusted or the wiper is reduced by one or two sizes, it still no work, in order to solve the issues totally, you need to replace the wiper arm spring in the 4S shop;
In addition, some cars inborn are having small pressure , such as Chery QQ, BYD F3 and some Japanese and Korean models, The multi-function wipers are designed in accordance with windshield curvature of most cars, for example, wiper pressure is designed in weight of 0.5/kg, but the weight of the hook arm of some car model is only 0.4kg, which makes the middle part of the rubber refill strip has not enough pressure to adhere to the windshield of the car, then it will appear unclean wiping . It is recommended to reduce the wiper by one or two sizes to solve the issue.
However, reasons are also caused wiper quality. For example, there is a large deviation between the overall curvature of the wiper and the curvature of the windshield. In this case, it is recommended to select a suitable wiper and size.
