How to remove fog from the front gear in the most economical way

The first type of method - with special defogging products.

In many markets and places such as auto parts cities, there will be some stalls selling special products for defogging and anti-fogging, such as defogging agents or fog towels. This kind of defogging agent is sprayed on the inner surface of automobile glass, and wiped clean, while removing glass dirt, it can also form a thin layer of transparent protective film on the glass, which can prevent the condensation of water vapor on the glass and form a fog layer, spraying can prevent fogging for ten days - half a month. Of course, the way to spend money to save trouble, for a simple problem like fog, spending this money must not be the most cost-effective.

The second type of method is fenestration convection.

If the fog is not large, we can open a gap in the windows on both sides (this cannot be done when it is raining), so that the air inside the car will be convection, and the temperature inside the car will slowly approach the temperature outside the car, and the fog will dissipate. The advantage is that it can achieve the effect of turning on the air conditioner without increasing fuel consumption, but this method is not suitable for all situations, such as in the cold winter and when it rains.

The third type of method is the use of air conditioning systems.

The usual practice is to turn on the fan and refrigeration switch in the car, so that the cold air blows on the glass and the fog will soon disperse, and the effect is quick and direct. This is because the cold air blows onto the glass, forming a "cold film" on the surface of the glass, preventing carbon dioxide from condensing on the glass and having a defogging effect. One of the biggest drawbacks of this method is that the people in the car may feel very cold, just imagine that in rainy days and winters that are prone to fog, the taste of blowing air conditioning in the car is really uncomfortable!

Blowing for a few minutes may turn off the air conditioner, and after a while the fog starts to hang on the glass again, and the air conditioner ...... turned on againThis repeated operation is inconvenient and the temperature in the car will be very unsuitable, and the operation of the head down has caused certain hidden dangers to safety. Of course, if you are physically strong or have just finished an intense workout, this method can also be useful.

The effect of blowing glass with hot air is better than blowing with cold air, but the process is much slower than that of air conditioning. When it is first opened, it will indeed make the fog on the inside of the glass bigger, because the temperature difference between the inside and outside is greater, and after the hot air dries the moisture in the car, the glass will become transparent, and the process will be good for a few minutes. The operation process is to park the car on the side of the road, turn on the hot air, adjust the temperature to 25 degrees or higher, and wait for the fog on the inside of the glass to dry and then reduce the temperature to be OK, so that it will not fog up again during driving, because the car is dry.

The fourth type of method - detergent anti-fogging.

If you still find the above methods difficult to remember and cumbersome to operate, you might as well mix the "anti-fogging agent" ourselves to prevent fogging. There are also a lot of tips and tricks on the Internet, and the simplest is to mix with washing spirits. The ratio of washing spirit and water is 1:

10 or so, then use absorbent cotton or a clean and soft cloth dipped in it and apply it to the inside of the front and rear windshields.

You can turn on the air conditioner so that there is no fogging in the interior glass. You can also rub a little wax on the glass.

Here's how:

1. Defogging with air conditioning system.

Defogging with an air conditioner is a common practice. Turn on the cold air to blow the glass, and the defogging effect is very straightforward. But the people in the car can also feel very cold, and if the moisture in the car does not dissipate, the fog will not be long before it will appear on the glass again.

The effect of blowing glass with hot air is better than blowing with cold air, but the effect comes more slowly than with cold air.

It is best to turn on the hot air first when parked, and then pick up a rag and wipe it again. In addition, opening the external circulation during driving can also prevent fogging to a certain extent.

2. Open windows for convection.

If the fog is not large and the outside temperature is not very low, you can lower the windows on both sides to allow the air in the car to convection, and the temperature inside the car will slowly approach the temperature outside the car, and the fog will dissipate.

3. Detergent anti-fogging.

The method of blending "anti-fogging agents" to prevent fogging has been well known to many people. The ratio of washing spirit to water is about 1:10, and then use absorbent cotton or a clean and soft cloth dipped in it to apply it to the inside of the front and rear windshields, and then wipe off the remaining watermarks left on the inside of the glass after drying. It will work better with an air conditioner.

Three methods. 1) If there is a skylight, you can open the skylight; bai

2) If there is no skylight, you can open a small gap in the window;

3) If it is not suitable, you can use the cold air of the heater or air conditioner to blow the front windshield, and the need to turn on the warm air or cold air mainly depends on the ambient temperature and the temperature difference between the inside and outside of the car.

1. The main reason is that the glass of the car is in contact with the outside world, the temperature is lower than that of the socks, and the combustion of water vapor in the car is formed by condensing on the glass.

2. To eliminate fog, you can use cold air to remove fog, or you can use warm air to remove fog. Both methods help us eliminate fogging from the glass. Of course, you need to adjust the knob of the air outlet to the front windshield outlet position or press the defogging button.

Due to the low temperature in winter, the cold air defogging method makes the interior comfort of the car poor, and is generally rarely used. The air circulating into the car, the warm air blown out after the engine is preheated, can not only remove fog but also heat, plus do not need to start the compressor, the fuel consumption is naturally reduced, which is more acceptable to everyone. However, on rainy days in winter, due to the high humidity in the air, the effect of using heating to remove fog is not obvious, and sometimes it will aggravate fogging.

At this time, the last resort is to use air conditioning for heating. Because in addition to regulating the temperature, one of the most important functions of the air conditioner is dehumidification.

3. The principle of hot gas defogging is to increase the temperature in the car, dry the fog on the front windshield, and then continue to increase the temperature in the car, dry the moisture and moisture in the car, and prevent the fogging caused by the temperature difference between inside and outside the glass after drying. Correct operation method, if there is fog during the drive, please park the car safely first. Then turn on the warm air to more than 25 degrees, wait for two or three minutes, wait for the temperature in the car to come up, observe whether the fog on the front windshield has signs of dissipation, if there are signs of dissipation but not completely removed, you can use the front windshield defogging switch, which will speed up the removal of the fog from the front windshield.

As soon as the fog on the glass dissipates, turn off the defogging switch immediately, and continue to turn on the hot air in the leather store, which can temporarily increase the temperature. In this way, you can continue on the road, and when you feel that the temperature in the car is high, you can turn the hot air air conditioner switch down.
