[China Glass Network] In the early spring, the fog on the glass affects the line of sight. Especially in the weather with high humidity such as rainfall or snowfall, the fog on the glass will be more serious than usual. Many people use paper towels or rags to wipe them. In fact, this is a less desirable method. It is inconvenient to say that it is dangerous to wipe the glass during driving. In fact, there are many ways to deal with fog, and sometimes it will work well when combined. Today, I will give a detailed introduction to the method of defogging the car glass.

The reason for the fogging of the window is mainly because the temperature difference between the "internal heat and external cooling" is large, so that the moisture in the car is cold on the glass, and it is easy to form a mist. Defogging is also a targeted measure for this main reason.
Air conditioning system
It is common practice to use air conditioning defogging. Adjust the air volume appropriately and turn on the cooling switch. At this time, the cold air will blow onto the glass, and the mist will soon be exhausted. The effect is very direct and direct. This method has a big drawback, that is, people in the car may feel very cold, and it may turn off the air-conditioning after a few minutes of blowing. After a while, the fog will start to hang on the glass and air-conditioning will be required.
In addition, hot air can be used to remove mist. Turn on the hot air, no additional energy consumption, and you can drive 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 cold air. When it is just opened, it will make the fog inside the glass become bigger. This is because the temperature difference between the inside and the outside is even bigger. After the hot air dries the moisture in the car, the glass will become brighter and the process will be a few minutes. Because the car is dry, it will not fog again for a long time. Therefore, it is recommended to use hot air to defogg before parking, and then keep on the road to keep it fresh. In addition, the opening of the outer circulation during the driving process can also prevent the generation of fog to a certain extent.
In addition to the front windshield, the side windows will also fog, and the fog on the front side windows will affect the driver's viewing of the rearview mirror. Nowadays, the car has a separate air outlet for the front side window, but it is generally small. If the effect is not obvious, we can close the two central air outlets, so that the air outlets on both sides can be made larger. Air volume.
Summary: The air-conditioning defogging effect is very fast, but the car will be colder; the hot air effect is slightly slower, such as hot air de-fogging before going on the road will be very refreshing and warm.
Window convection
If the fog is not large, you can open a gap between the windows on both sides, so that the air inside the car will convect, 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 air-conditioning and does not increase fuel consumption, but this method can not be used in all situations, such as cold winter and rain.
Summary: This is a good method when it is not raining and the temperature is acceptable. The disadvantage is that it is not suitable for running at high speed.
Detergent anti-fog
The method of blending "antifogging agents" to prevent fog has been well known to many people. The ratio of washing spirit to water is about 1:10, then apply it to the inside of the front and rear windshield with absorbent cotton or a clean soft cloth. After drying, wipe off the watermark left on the inside of the glass. It works better with air conditioners.
Tips: It can be effective in 10-15 days, with little cost, but the operation process is cumbersome.
