Car wipers are like a layer of fog after scraping

It is likely that there is an oil stain on the glass, and the water stains are easy to condense into water droplets after encountering water, and they cannot be removed. If you accidentally touch oil stains on the windshield or wiper of your car, you won't be able to clean the rainwater. This is usually the phenomenon of accidentally getting oil stains on the glass and not noticing, and when it rains, using the wipers causes this phenomenon.

So usually pay attention to the cleanliness of the windshield. Guaranteed safe driving.

A windshield wiper is a sheet structure installed in front of the windshield, consisting of an electric motor and a reducer.

The four-link mechanism, wiper arm mandrel, wiper blade assembly, etc., the main function is to sweep away the rain, snow and dust that obstruct the sight on the windshield.

The scientific name of windshield wiper (windshield wiper) refers to the sheet structure installed in front of the windshield, which is composed of an electric motor, a reducer, a four-link mechanism, a wiper arm mandrel, a wiper blade assembly, etc., and its main function is to sweep away the rain, snow and dust that obstruct the sight on the windshield. [1]

Intermittent flexible wipers are adjusted by the driver according to the rain and line of sight. The difference from the wipers installed in other ordinary cars is that it can automatically raise and lower the wiper speed according to the change of vehicle speed.

Because in the same amount of rainfall, the faster the car, the more rain will be on the way, and if you stop, the deceleration of the wipers will reduce the noise.

Wipers, many riders may not care. In the sum of cars, the wiper is a relatively small component. However, according to the International Driving Safety Survey, it is revealed

When driving in the rain, the rate of traffic accidents caused by aging wipers is about 5 times higher than usual. During the shower season, if something is wrong with your wipers, you should repair or replace them as soon as possible.

Hello, car owner. Change a pair of wiper blades, if it doesn't work, you can go through the glass with 2000 beauty sandpaper. Remember it's 2000 beauty sandpaper, too thick will hurt the glass.

Hello, wash the glass, replace the wiper blades, thank you for your support to the car master, and have a great life.

Hello! Just turn on the air conditioner and blow the windshield, I hope mine can help you.

If the wiper blade is too dirty or aging, clean the wiper blade with a wet towel first, not only replace it.

Hello, this is caused by the aging of the wiper and the unclean scraping, just replace the wiper blade.

The car wiper is blurry after scraping the glass, and it feels like there is a layer of fog when it is scraped. It could be that the glass is contaminated with contaminants such as gums, bird droppings, insect carcasses, etc. If you don't erase it the first time, it's hard to clean it up later.

This contaminant is highly mucosal and corrosive. If it is not cleaned for a long time, it will gradually corrode the car glass and become more and more difficult to clean. Even after removal, the glass may leave signs of wear.

In addition, the mist may be an oil stain that has accumulated over the years. The oil has strong adhesion, is difficult to dissolve, is difficult to wipe off with a windshield wiper, and may form an oil film over time, which will present a foggy feeling on the glass.

If the glass is dirty, it can be treated with a special cleaning agent, which can quickly dissolve the contaminants and is more efficient to use. In addition, car cleaners have a special anti-corrosion function, which will not cause damage to car glass and plastic parts when removing dirt, and can also better protect car paint. If you don't have a professional car cleaner nearby, you can also try household white vinegar.

Let it sit in place for five minutes, then wipe it off with a cloth. White vinegar itself has a certain detergent ability and can play a certain cleaning role.

Of course, it is also possible that the car has been exposed to the sun and rain for a long time, resulting in an oil film on the front glass, which is difficult to clean when exposed to water. All we have to do is pour a basin of water on the glass, if there are a lot of small droplets attached to it, there is indeed a film of oil on the glass. In this case, it needs to be removed with a professional glass cleaner.

The oil film on the glass can be sprayed with oil film, because the liquid sprayed by the oil film spray has the effect of dissolving oil similar to household cleaners, and the oil film is mostly the product of the mixture of automobile exhaust and oil smoke, therefore, the contact will form a mixture that is easy to erase, which can be easily removed with a cloth.

If the wiper is more aged, it will also cause the wiper to be unclean, after all, each item has its own service life. Especially for vehicles that are often parked on the street, the rubber of the wipers will harden in the sun, so the effect of the brushes is naturally not so obvious and needs to be replaced in time.

Generally, family car wipers are equipped with standard, fast and slow three gears, which can be adjusted, generally on the right side of the steering wheel. There may be some differences between models.

The manual wiper adjustment method is as follows:

Light rainfall: Don't rush to use wipers when it starts to rain lightly. Spray glass water to moisten the glass before opening it for the first time to avoid dry scraping of the glass window due to lack of moisture.

Heavy rainfall: If the rain is heavy, adjust the working frequency of the wiper in time to ensure a clear vision. If the rain is too heavy and the rain is too urgent, and you still can't see clearly when you drive to the highest gear, it is recommended to find a safe place to stop temporarily and wait for the rain to lighten, and remember to turn on the fog lights and double flashes when parking on the side of the road to avoid accidents.

Use rear window wipers: If your car has a rear wiper, don't forget to turn it on when it rains.

Generally, SUVs, hatchbacks, MPVs and other models are mostly equipped with rear wipers, this is because the rear windshield of the sedan has air flow through, while the hatchback or SUV does not, which leads to the fact that once there is rain, the sedan can use the air flow to blow down the water droplets, but the hatchback cannot, the water can not be blown off in time, it will be easy to stick to the dust, affect the sight of the rearview mirror, and lead to unsafe driving.

Hope, thank you.

It may be that the wiper is damaged, it may be that the fuel is not good, it may be that there is oil on the glass, and it may be that the rubber strip is aging.

It may be that there is some contamination on the glass, which is very difficult to clean and cannot be scraped away by the wipers alone.

Because the quality of your wiper is not very good, the wiper is not very clean, so it will feel like this.

Hello! Glad for your question.

1. Wiper blade aging: two wiper blades are rubber products, which will be aged and hardened after a period of time, and it is more significant in winter. Most wiper blades are recommended to be replaced every one to two years.

2. There is a foreign object in the middle of the wiper blade: when the wiper is opened, there will be a sharp sound of friction between the wiper blade and the front windshield.

3. The installation angle of the two wiper arms is wrong: it will affect the wiper blades to jump on the windshield, then it will cause a sound. If the two wiper blades are normal, you need to adjust the angle of the wiper arm so that the two wiper blades are perpendicular to the windshield plane.

[Reason]: Engine exhaust, especially the blue smoke of large buses, is caused by a lot of oil.

Introduction]:

1. After the wiper blade is used for a period of time, the rubber begins to age and harden, and the strength of the back press (sometimes the back spring is reduced) can not flatten the wiper blade, so there is a gap about 10cm wide in the middle of the wiper blade, and the rain will not be clean.

2. Because the temperature of the front windshield is too low, the cold spot of the glass water is not enough.

3. The wiper has been used for a long time, and the old one can also be polished by yourself, and the effect can be improved, and the new wiper is the most direct.

1. Because the temperature of the windshield is too low, after the wiper is wiped, the residual thin water film will show signs of "frosting" on the surface. You can use the wipers to blow again, or turn on the front windshield to blow the air, and wait for the temperature to come up before walking.

2. Sprinkle laundry detergent on the glass, wipe it with a towel a few more times, and rinse it with tap water. Wipe the inside of the windshield with a little dish soap and a little water before dipping a towel on it.

3. You can get a new wiper. Or buy a few bottles of all-purpose cleaner to spray a few times when it rains, then rinse off with a glass of water. The general situation is that the wiper has not been used for a long time, the glass is oiled, ash or something on the glass, it has rained recently, the glass has not been cleaned and the wiper is directly opened and scraped, and the wiper blade is easy to break, if the wiper blade is not very good before, the result is not clean.

First of all, we need to check whether the wiper blades are aged, hardened or cracked, resulting in unclean scraping and blurring on the glass. If this is the case, we need to replace the wiper blades with new ones.

The general service life of wiper blades is about 40,000 kilometers in two years. If there is no problem with the wipers, it may be because the wipers are mixed with some impurities, resulting in scratches between the wipers and the glass, and it is recommended to clean the wiper blades. It is also possible that there are foreign substances such as shellac on the surface of the glass, which makes it difficult to remove it even under the wiper brush.

At this time, we have to clean the glass and then do the wiping test.

In addition, if the external oil and gas are gradually adsorbed on the windshield during daily driving, and then after a long time of high temperature oxidation, it is difficult to remove, due to the mutual repulsion between oil and water, it is easy to form irregular water stains and matte surface on the glass. The windshield needs to be washed.

How it works. An electric motor on an electric wiper, which drives the output shaft through a worm gear on the armature shaft and drives the output gear through the idler pulley and idler shaft, and then the output arm connected to the wiper connecting rod is manipulated by the output shaft. When the motor rotates, the output arm and connecting rod are driven to move in the forward and backward directions.

A resistor located on the control switch is connected to the armature winding of the motor to control the speed of the motor, and the driver can flip the switch as needed to flow current into the input circuit of the motor.

You only need to turn on the defogging function to solve the problem. So that you can have a better driving sight.

Turn on the defogging function. Park your vehicle in a safe area. Minimize the number of times you drive your vehicle on rainy days.

In the end, I personally think that the main reason why the front windshield fogs up is because of rainy weather. So overall, I think drivers want to avoid fogging up the front windshield. Just reduce the number of trips on rainy days.

After all, traveling on a rainy day will not only fog up the front windshield of the car. In addition, it will also be a big obstacle to observe the road surface due to rain.

In this case, it may be because the rubber strip on the wiper brush has deteriorated, resulting in the rubber strip not fitting together with the front windshield, and the rubber strip can be replaced to solve the problem. It may also be because the adhesive strip on the wiper brush has sand, dust and other impurities attached, and the glass is scratched when scraping, so you can use sandpaper or toothpaste to polish it.

You can open all the windows to ventilate the car, so that the fog in the car can dissipate quickly, or you can turn on the air conditioner and turn it on to the outer circulation, and all the fog in the car will be discharged, which will also make the fog all dissipate, or you can spray a little water on the glass, and then let the windshield wiper go to scrape to see clearly.

In such cases, it is necessary to use other materials for cleaning, which can have a particularly good effect.

This is because the air temperature difference between the inside and outside of the cab is relatively large.

The fog outside the windshield is cleaned and scraped again, and the temperature of the cab can be appropriately increased, so that the difference between the air temperature inside and outside the cab is not too large, and the windshield will not fog up without giving the condition of water vapor condensation. If the fog is severe, you can use the wipers to blow it off first, and then blow a little hot air in the direction of the windshield appropriately, and the fog will dissipate immediately.

In winter, we can turn on the hot air, and to open the external circulation, must not be the internal circulation, and then slowly the fog will disappear, if the fog is not clear, this method needs to stop first, because it will not be removed too quickly, it will take a few minutes, do not turn off after removal, there will be no fogging.

In the summer, cold air can be used to open the external circulation, which also removes the fog and removes it quickly. This is to choose cold or hot air to defog according to the weather, and also consider the actual situation.

The outside fogs are caused by the fact that the temperature inside your car is lower than the outside of the car, for example, if you drive the cold air in the front gear.

The temperature difference between the inside and outside is large, turn on the air conditioner and the wind direction is on the front shield, five seconds is good, but it is not suitable in winter.

Turn on the external circulation, turn on the air conditioner, adjust to the blower position, OK
