1 Men, pay attention to the diligence and thrift, buy and buy necessary things, and save other things

If there is an "old driver", remind me! Say that there is no need to be afraid of the abnormal sound of the wipers, and there is no need to change so diligently, they have a basket of "soil methods"! "Sewing and mending" can fight for another 3 years, can the wiper noise be repaired by itself? You taste, you taste... Wipers not clean? Or an annoying noise? After all, there are two reasons:

One is that there is an oil film on the glass, often you have just coated the film or crystal, and the hydrophobic layer on rainy days is there, but the wiper blade is slippery because of this.

The second is that the wipers are hardened or stained, and the main component of the wiper strip is natural rubber, which will inevitably be dirty and aging when exposed to the sun and rain all year round. Here comes the "local method" recommended by the old drivers:

(1) Test sample:

Whether it is to remove oil film or dirt, "old drivers" will recommend us the following artifacts: rain preventer, wiper essence, dish soap, Mr. Vermeer (oil hyacinth)

(2) Test Method:

Find a car with an abnormal wiper sound, use the above artifacts on the glass respectively, and then use a decibel meter to test whether the abnormal noise is weakened, let's see, whether it works or not, and officially enter the test link:

1. Dish soap
As soon as the dish soap was sprayed, the noise disappeared for a while, but when this layer of "soapy water" gradually disappeared, the abnormal sound of the wipers also returned. Decibels: 80.3dB

2. Wiper essence (diluted)
The essence of wiper essence is to concentrate glass water, and it can't do things that glass water can't do. Decibels: 81.8dB

3. Rainproof
To put it bluntly, the rainproof agent is "micro crystal plating", which adds a hydrophobic layer to the glass, which has no effect on improving the abnormal noise of the wipers, and even adds some chaos. Decibels: 81.7dB

4. Mr. Mighty Man
Mr. Weimeng, who is strongly decontaminated, or the oil hyacinth, is also helpless, and the abnormal noise is not significantly improved. Decibels: 80.4dB

(3) Test results:

Judging from the test results in the table above, the local method recommended by the so-called "old drivers" is completely ineffective!! It cannot cure the unclean scraping and abnormal noise

However, there is a very small probability possibility, that is, the angle of the wiper rod has deviated, at this time, you can open the wiper dust cover, adjust the spring tightness to complete the debugging, because you may use a professional wrench and sleeve, here it is recommended that you still find a professional to debug

How often do you change your wipers? It is recommended to change every 6 months. The above experiment is to tell you to change the wipers regularly, and it is not saved! Under normal circumstances, it is recommended to change the wipers once every 6 months, otherwise even if the wipers can continue to be used, the harm caused by them is many: aging and cracked wipers cannot scrape clean rainwater and stains, which will bring hidden dangers to driving safety; The beating of the wiper will not only bring abnormal noise, but also increase the wiping resistance, resulting in overheating and damage to the wiper motor; Aging wipers can scratch the windshield.

So how do you change the wipers? Before replacement, it is necessary to find out the wiper specifications include: how many inches? What interface? In general, boneless wipers scrape cleaner than boneless wipers

When replacing, you should first turn the wiper arm up, break the old wiper buckle and replace it, here pay attention to a towel on the glass, otherwise the rocker arm spring rebound is very easy to damage the glass! ↓That's the lesson↓

After replacement, you need to check the fit of the wipers to see if there are signs of unclean scraping, so far, the wipers can be easily replaced! http://www.yuguanwiper.com
