Is there anything I can do if the front windshield is foggy?

1. Turn on the hot air.

The effect of hot air blowing glass is better than blowing with cold air, but the process is slower than that of air conditioning, and it will indeed make the inner glass fog bigger when it is first opened, because the temperature difference between inside and outside is greater, and after the hot air dries the moisture in the car, the glass will become transparent and dry, and it will not fog up again for a long time.

2. Turn on the cold air.

Pay attention to the air volume to be appropriately increased, and at the same time turn on the refrigeration switch, some cars have the option of direct defogging, you can turn on the option, the cold air will blow to the glass The fog will soon dissipate, and the effect is very fast and direct. However, this method also has the disadvantage that the driver will feel cold, and the fog will appear again after turning off the air conditioner.

3. Open the gap in the window.

In the case that the fog is not particularly large, you can consider opening a gap in the windows on the side or side of the driver or co-pilot, if it is particularly heavy rain outside, it is recommended to open the car with a rain shield, and it is not recommended because the rain is likely to seep into the car.

4. Anti-fog spray.

You can buy car defogging spray in physical stores or **, you only need to spray a small part on the glass of the car, and then wait for a while before wiping it clean. At this time, a protective film has actually been formed on the glass, and the water vapor cannot stick to it, and when we drive, we will find that the effect is very good, and it can last for several days. Such a spray is not expensive, and the only drawback is that the taste is relatively large, so you still have to pay attention to it.

Air conditioner defogging. This is the easiest way, just turn on the front window defogging mode, then turn the wind speed to the maximum, turn on the A C switch, and then turn the temperature to the lowest, and the fog on the glass will disappear in a while. In addition, the rear windshield and exterior mirrors of some models are equipped with electric heating, which can be used to eliminate fogging in about a minute after the switch is turned on.

Air convection. This method is suitable for very few situations, after opening the window, it can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the fog formation conditions, this method seems to be very economical, but the situation that is really suitable is too little, if it is raining outside, it is impossible to open the window, and the wind blowing in is also quite limited.

The above two methods of defogging agents are emergency measures in case of fogging, so is there any prevention in advance? Of course, there are ** defoggers on the market ranging from tens of yuan to hundreds of yuan, and the ingredients are not much different, and the only difference may be the durability. To use it, you only need to spray it evenly on the glass surface and wipe it clean with a dry towel.

Its principle is to use the method of surfactant to retain a certain protective film on the surface of the glass, change the surface tension of water molecules, and make the fog beads condense into large water droplets, so as not to block the line of sight. Other glass in the car can also be used, especially in exterior mirrors.

Dish soap homemade defogger.

If you forgot to buy a defogger and want to use it temporarily, then mixing dish soap with water is a good method, according to the ratio of 1:6 to the dish soap and water, put it in a bottle, spray it before traveling, the effect is comparable to the defogger bought outside, but the durability is slightly worse. Some car owners asked if they could use soapy water, hand sanitizer, laundry detergent and other alternatives to dish soap?

Yes, yes, but none of them are as effective as dish soap.

The cause of fogging in the car

This is because these cars are all automatic air conditioning, and when the warm air is turned on and defogged, the air conditioning system automatically turns on the compressor and adjusts to the external circulation. This is crucial.

First turn on the external circulation, the humidity outside is higher than inside the car, otherwise the fog will run outside. Therefore, the opening of the external circulation allows the air with lower humidity to be sucked in, and then the compressor is also turned on and the evaporation tank produces a very low temperature.

When the air with lower humidity outside passes through the cryogenic evaporation tank, the water vapor inside will turn into water droplets and remain in the evaporation chamber at low temperatures, leaving the air with lower humidity. The relatively dry air continues to advance towards the warm airbox, and the heated dry air blows towards the windshield, instantly absorbing the water vapor on the windshield.

The cause of fogging of the windshield of the car: due to the temperature difference between the inside and outside of the car, the temperature in the cab is higher than that outside, causing the water vapor in the cab to condense on the inner windshield to form fog. This phenomenon is more common in winter!

Solution: 1. Open a little window, but this method is not good for rainy days, which will cause rain in the cab.

2. Wipe off the fog with a rag, this method treats the symptoms but not the root cause, and when it is wiped off, the water vapor will condense into fog again.

3. Turn on the air conditioner, turn on the air conditioner for a while, and then turn on the heating after the fog dissipates. Then adjust the air conditioner to blow towards the windshield so that the hot air from the blow can evaporate the fog.

4. Wiping the inside of the windshield with a rag dipped in dish soap or a special anti-fogging agent can also effectively prevent the glass from fogging.

The development of modern sedan appearance is closely related to the development of glass technology. As early as more than 40 years ago, the front windshield of a sedan has adopted a single-piece curved windshield, and gradually abandoned the flat windshield.

“1.Warm up the car enough to allow the engine water temperature to rise. When there is frost on the windshield in front of the vehicle, you can't use the wipers to scrape the ice, you should heat the car in situ, and never slow down to warm the car, after all, the view is blocked and you can't see anything.

You need to wait patiently for the water temperature of the engine to rise, and do not turn on the heater while waiting. 2。Warm air blows on the front windshield.

When the engine water temperature rises, turn on the heater and turn it to blow the windshield upwards to turn the heater on.

When the temperature inside the car is quite different from the temperature outside the car, the glass inside the car will produce water droplets, the landlord can open the window a little bit to let the air in the car circulate, and the water droplets will disappear, thank you.

Fogging of the windshield in winter is very common, and every driver should have encountered it, and the fog is on the inside of the glass. When driving in the summer, the windshield will also fog up on rainy days, but the fog is on the outside of the windshield, which also affects the vision. Why does the outside of the glass fog up?

How should I defog it after fogging? The defogging method is different from winter.

Car glass is easy to fog, teach everyone a good way.

The cause of windshield fogging is caused by a large temperature difference between indoor and outdoor in winter. If the driving environment is more complicated during driving, you can use the cold air to carry out, which has the advantage of quickly removing the fog on the windshield and avoiding the inability to see the road due to fogging. However, because the indoor temperature needs to be high in winter, after removing the fog, the temperature should be adjusted to the warm air position several times to prevent the fog from reappearing.

If you are in the parking phase or just hot car stage, you can directly use the way of blowing warm air, although the fog removal time is relatively slow, but the warm air should be turned on all the time, if necessary, turn on the front windshield defrost function. This prevents the fog from re-generating and meets the temperature needs of the indoor driver.

Each car next to the nuclear knowledge has a special defogging button, in the case of turning on the air conditioner, press the defogging button, you can remove the fog from the front windshield.
