The wiper is not clean, is it the reason for the wiper or the glass?

2022-01-18

[China Glass Network] I don`t know if the owners have encountered this kind of situation, and they can`t use the wiper several times a year, but they don`t use it for a long time, and find that it`s better to slap it, but it`s more dirty. Why is it? Is it the cause of the wiper or the reason for the glass water?

First, the glass is not clean

Usually, the car wash does not clean the glass well, and the surface of the glass is adhered with fine tar particles, etc., which will reduce the surface finish of the glass. The rough glass surface will not only be scratched, but also will hurt the wiper strip.

Second, the wiper strip is rough

If the original wiper strip is properly maintained, its life can reach 5 years. Therefore, pay attention to the usual maintenance, and remove the fine sand on the wiper strip in time. Scraping with these fine sands is equivalent to sanding the wiper strips with a grinding wheel. Soon, the donkey's strips must have been cleaned of rain.

Therefore, every time you wash your car, you must use your own hands to clean the tiny sand particles on the wiper strip.

In addition, parking in the summer, try not to expose to the sun, because rubber products are more afraid of direct ultraviolet rays, easy to age and hard.

If the wiper is found to be unclean, most of them are caused by the roughening of the rubber strip of the wiper. In fact, the rubber strip is not aged and hard. Just think of ways to make the rough rubber strips smooth and polished.

Then, if the aging of the rubber strip is found to be mutated, how can it be restored?

1, preferably remove the two wipers

2, prepare a water sandpaper

Water sandpaper for 2000 purposes can be bought in the paint shop, the price is very cheap, and it is enough to buy one for several years. Tear the water sandpaper into small pieces, and use a small piece each time.

3. Soak the wiper and water sandpaper with water.

4, sanding the wiper with water sandpaper

Note that the strip is like a kitchen knife. You not only have to polish both sides, but also properly grind the front side of the strip. The time does not need to be very long, it will take about 5 minutes.
