The frost truck will suffer first? Skills of removing fog from windshield

The first frost is the last solar term in autumn. At this time, as the name implies, the first frost has appeared in various places, and the fog has gradually increased. At this time, the majority of car owners often have to worry about the fog on their car windshield. So today, let's take a look at the tips of removing fog from the windshield in the first frost solar terms.

The reason why the window is foggy is that it is hot inside and cold outside. When the temperature difference between the inside and outside of the car is large, the water vapor exhaled by the occupants in the car will condense into water vapor when it meets the cold glass. This is an old problem, but it is not a small one. Once the driving line of sight is blocked, accidents may occur within a few seconds, so defogging is essential. The following are several defogging methods compiled by Bian Xiao for you. Let's compare it together.

The most primitive method: wipe with a dry cloth or paper towel.

Advantages: immediate results.

Disadvantages: laborious, unsafe, and will leave traces after rubbing.

The most primitive method is to wipe the glass directly with a dry cloth. This scene must have been seen by many citizens: the old driver always keeps a towel and tries to clean the glass when stopping at a red light. The disadvantage of this method is that it is laborious. There will still be traces on the glass after wiping, and it will fog again soon. If you wipe while driving, it is easy to cause an accident.

The most convenient method: blowing with hot air.

Advantages: no distractions

Disadvantages: the effect is slow, and other windows are still foggy.

The second method is to blow directly with hot air. However, the effect of this method is relatively slow, and the fog on the front windshield is getting bigger and bigger just after the hot air is turned on when the vehicle is driving, and the glass will gradually become clear after more than ten minutes.

The most creative method: cleaning agent combined with dry cloth to wipe

Advantages: Good preventive effect.

Disadvantages: deal with it in advance.

The principle of this method is that the detergent contains surfactant, which can change the surface tension of water and make the fog droplets condense into large water droplets quickly, thus achieving the effect of anti-fog. The specific operation is to mix the detergent with water in a ratio of 1: 6 on sunny days, then evenly smear it on the glass inside the car with a sponge, and then wipe it clean with a dry cloth without leaving any traces.

The defogging effect of this method generally lasts for half a month, which is better than the first two methods. However, this method is a preventive measure and must be dealt with in advance. If the owner waits until the fog is found, it will be too late to operate.
