Car windows often fog up, which is very inconvenient for car owners. They don't see road ahead at all. This may be no different than lighting a car with high beams, except that it's not dazzling.
The cause of fogging is largely related to temperature difference between inside and outside car. This phenomenon most often occurs on rainy days and at low temperatures, which can easily lead to fogging of windows, especially windshield.
Some car owners think that it's okay, you can use a windshield wiper to remove fogging.
When temperature outside car is low and temperature inside car is high, there will be a temperature difference. Due to phenomenon of condensation, when water vapor is cold, it condenses into fine water droplets, which cause windows to fog up.
Regarding fog removal, it's actually very simple.
1. The easiest way is to turn on air conditioner and heat it to blow it to reduce temperature difference between inner and outer surface of glass, thereby removing fogging on glass, but there is a small problem, that is, fogging on both sides and rear windshield may not go away so quickly.
2. Open convection window, open a small gap of windows on both sides, and release moisture by air convection, thereby reducing water sticking to glass. In layman's terms, this should reduce problems in car and allow temperature inside and outside to reach a balance.
3. Use anti-foggers. There are anti-foggers on market. Of course, you can also make them yourself. If you want to keep it simple, alternatively you can use detergent, soapy water, salt water, etc. It depends on the actual situation.
These days, cars are equipped with an anti-fogging function. Simply adjust temperature of air conditioner to lowest level and then turn on defogging function. In short, it should reduce temperature difference between inside and outside of car in order to realize anti-fogging function.
Anti-fogging method for car windows 1. Wipe with a cloth
It's good to wipe window with a rag when it fogs up, so we put a cotton rag in car. However, this method is inefficient and cannot keep anti-fogging state all time, and it is easy to cause a traffic accident at same time as driving, so it is good to wipe rearview mirror with a cotton cloth.

Of course, reasons for formation of fog were also mentioned above. The most fundamental solution is to open windows for convection, so that ambient temperature inside car is same as outside car, and there is no reason for fog to stick to glass. This method can really solve the problem, but it also has disadvantages: as a rule, foggy days are accompanied by rain, so it is not recommended to open windows.

As a general rule, vehicles equipped with air conditioning have an anti-fogging function. Lightly press anti-fogging button and defogging will continue without any problem and effect will be immediate. However, this raises a new question: Is cold or hot air being used to prevent fogging?
The principle of cold wind defogging is actually similar to that of convection demisting. It maintains same temperature inside and out so mist doesn't stick to glass, so cold wind defogging doesn't seem to be good for winter.
The hot air defogging effect is best. It uses principle of hot air to vaporize mist to achieve de-fogging. The time is shorter than demisting with cold air. Immediate effect - elimination of fogging with hot air.
Automotive glass anti-fogging method 4, anti-fogging agent
There is also something called an anti-fogging agent on market, and price of a certain treasure also ranges from 9.9 to 40 yuan. Some boast that there is a 2-year effect, which seems unrealistic, but does allow you to achieve effect of sweating to a certain extent.
Of course, after we've covered so many ways to deal with fog inside a car, what about fog outside a car? Everything is very simple, when windshield is fogged up, turn on wipers, if side windows are fogged up, windows will rise and fall once; As far as defogging goes, I hope this can help you, or if you have any more defogging tips, please share them in message area and chat with everyone!
