How do you remove fog from car glass?

How to remove fog from car glass?

Automobile glass defogging method uses air conditioning system, window opening convection, and detergent anti-fogging.

1. Use air conditioning system

It is common practice to use the air conditioner's defogging function. Turn the air volume up appropriately, and turn on the refrigeration switch at the same time, then the cold air will blow on the glass, and the fog will soon disperse, and the effect is very fast and direct. One of the biggest drawbacks of this method is that the occupants of the car may feel very cold, and blowing for a few minutes may turn off the air conditioner, and after a while, the fog will start to hang on the glass again, and the air conditioner will be turned on again.

In addition, hot air defogging is also possible. Turn on the hot air without adding extra energy consumption and driving comfortably. In fact, 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, this is 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 translucent, and the process will be good in a few minutes, because the car is dry, and there will be no fogging for a long time. Therefore, it is recommended to use hot air to defog first when parked, and then you can keep it fresh all the time when you go on the road. In addition, opening the external circulation during driving can also prevent fogging to a certain extent.

In addition to the front windshield, the side windows can also fog up, and the fog on the front side windows can affect the driver's view of the rearview mirror. Nowadays, cars have an air outlet that blows the front side window separately, but it is generally very small, if you feel that the effect is not obvious, we can close the two ** air outlets, so that the air outlets on both sides can get a larger air outlet.

Summary: The air conditioner defogging effect is very fast, but the car will be colder; The hot air effect is slightly slower, if the hot air is defogged before driving, it will be very refreshing and warm along the way.

2. Open windows for convection

If the fog is not large, you can open a gap in the windows on both sides to allow the air in the car to 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.

Summary: This is a good method when it is not raining and the temperature is acceptable, but the disadvantage is that it is not suitable for use when running at high speeds.

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 apply it to the inside of the front and rear windshields with absorbent cotton or a clean and soft cloth.

Allow to dry before wiping off any remaining watermarks left on the inside of the glass. It will work better with an air conditioner.

Summary of tips: It can be effective in 10-15 days, it costs very little, but the operation process is more cumbersome.

There are the following solutions to fogging outside the car window:

1. Open the window and remove fog: adjust the button of the car glass to leave a gap in the window to reduce the temperature difference and avoid the fog of the car. In this way, the air inside and outside the car forms a convection, the temperature difference decreases, and the fog will slowly disappear;

The limitations of opening windows to remove fog are very obvious, if the fog in the car is large, or it is rain and snow weather, or driving on the highway, it is not suitable to open the window to remove fog, and opening the window will also reduce the temperature in the car;

2. You can use a clean rag to wipe the fog on the car window;

3. Air conditioning defogging: you can use the vehicle air conditioning system to defog, at present, basically all cars on the market have air conditioning outlets under the front windshield, just select the air conditioning to the corresponding gear;

In winter, the temperature difference between the inside and outside of the car is too large, and it is cold outside and warm inside, causing the windows to fog up. At this time, you can turn on the AC refrigeration switch in the car to let the cold air blow on the front windshield, and the fog will disappear soon;

4. Detergent blending method is sprayed on the outside of the car window to defog: use soap and dish soap mixed with water to spray on the glass, and form a layer of oil film on the surface of the glass to achieve the effect of no fogging. However, this oil film will cause the front windshield to form a dazzling effect at night, affecting driving safety;

5. Defogging with wipers: The fog outside the window is generally caused by rainwater condensation, and it is okay to scrape with a wiper, but if it is a frost in winter, it should be wiped with water, not with a wiper to avoid damaging the wiper;

6. Use defogging agent: spray the defogging agent on the inner surface of the automobile glass and wipe it clean, which can also form a protective film while removing the glass dirt.

The method of driving the glass in the car is as follows

1. Wipe with a damp towel. Some particularly experienced car owners will prepare a wet towel in the car when the front windshield is easy to fog up. When driving, if there is fog in the car, then the owner can find a suitable place to park and then wipe the fog off with a damp towel.

This method is still very practical, but it can be dangerous. For example, if you encounter fogging on the highway, the owner can't find a place to park quickly, so you can use other methods.

2. Open the window. In fact, the reason for the fogging in the car is nothing more than because the temperature difference between the inside and outside of the car is too large, we only need to open the window, so that the temperature inside the car is the same as the temperature balance outside the car.

However, this approach has certain limitations. In the summer, this method works very well, and the windows can also make the interior of the car cooler. But in winter, if you use this method, the people in the car will feel very cold, and it is not good if you catch a cold and cause a fever.

Therefore, the limitations of this method are a bit large, and it cannot be used in winter.

3. Turn on the air circulation system in the car. Almost all cars today are equipped with an air circulation system, which can be used for air exchange. If you notice that the front windshield of the car is fogging, then you can turn on the increase system.

In addition, everyone must turn on the external circulation system, so that it can achieve effective defogging. And this method is very effective, and you don't have to worry about the cold air from the outside. But it also has a disadvantage, that is, it can't be driven for too long, and if you drive it for too long, the heating in the car will slowly disappear.

There are 5 solutions to fog on the car glass: air conditioning, refrigeration, and defogging; Crack the window; external circulation defogging; Use the car defogging function to defog; Open windows for convection defogging.

1. Air conditioning refrigeration defogging: using the air conditioning refrigeration effect to remove fog and reduce air humidity, you can remove window fog. Although it is fast and effective, it lasts for a short time.

2. Open a crack in the window: the main thing is to let the air inside and outside the car have convection, so that the water vapor breathed by the people in the car will flow to the outside world, so that the fog will be alleviated to a large extent.

<>4. Use the car defogging function to defog: If the front shield of the car is fogging, you can directly use the window defogging function.

5. Open the window for convection defogging: The fog in the car is not large, you can open a gap between the windows on both sides, so that convection will be formed inside and outside the car, the temperature difference will also be reduced, and the fog will slowly disappear.

Car glass has the hazard of fogging

When the side glass of our car is foggy, our view around the vehicle at night is much blurred, and it is difficult to spot when a pedestrian passes by.

When the fog appears in the front windshield, its hazard is the most serious, the fog will form a layer of blurred film, attached to the surface of the windshield, at night, the lights of the oncoming car will form a halo of halo, affecting the driver's line of sight, especially prone to traffic safety accidents!
