Windshields are prone to fogging up when driving in the rain.

The phenomenon of fogging up the windshield and side windows of the car comes from the temperature difference between outside and inside the cabin.

In Vietnam, drivers often encounter this phenomenon when driving in the rain or passing through cold weather areas with high humidity... The outside temperature is lower than the temperature in the interior compartment, along with the operation of the air conditioning system, the heat emitted from the people sitting in the car causes condensation on the glass surface. This obstructs the driver's vision, making it difficult to control the vehicle. Some experiences compiled from "veterans" as well as experts in the automotive field will help drivers overcome the phenomenon of foggy glass.

The temperature difference between outside and inside the cabin causes the car windows to fog up.

Turn on the glass drying function

Most of the current car models are equipped with a glass defogger function. Therefore, when detecting signs of fogging due to condensation, users should activate the glass defogger function via the button usually integrated on the center console.

When activated, the indicator light on the control button will light up to let the driver know that the windshield defroster function is working. Note, when turning on this function, you should close the windows on the car, because if just one of the windows is open, the windshield defroster system will not work effectively and it will be difficult to remove the steam on the windshield. This is considered the fastest and simplest way to fix the phenomenon of foggy car windows when driving in the rain.

However, with some older car models that are not equipped with a windshield defroster, users can also remove condensation on the windshield by adjusting the air conditioning system.

When turning on the defroster, close all car doors.

Adjust the air conditioner temperature appropriately

According to some experienced drivers, when the car windows are foggy, users should turn on the air conditioning system, gradually adjust the temperature to reduce the difference with the outside environment. In addition, you should choose the internal air intake mode to prevent moisture from entering the car, adjust the air vents so that the wind does not blow directly onto the windshield or the side windows. After a few minutes, the temperature will balance the amount of water vapor, and the windows will no longer fog up.

Adjust the air conditioner temperature appropriately

However, drivers should only use this method when the outside temperature is not too cold. Because if the user suddenly reduces the air conditioning temperature in the car to a level that is equal to the ambient temperature, it will somewhat affect the health of the people in the car.

Turn on the fan and switch to outside air intake mode.

On dry days, especially in the Northern provinces... When the air conditioning system is not working effectively, the cold is not deep. To avoid fogging, the driver should turn on the fan, switch to outside air intake mode and adjust the air vents on the windshield. This will help reduce the temperature difference between inside and outside the car, preventing the windshield from fogging.

Users can lower the windows to balance the temperature in the cabin with the outside.

In addition, to save fuel, some drivers also have the solution of lowering the window to balance the temperature inside the car with the outside. However, this method is only suitable at times when it is not raining too heavily and the weather is not too cold, to avoid affecting the health and interior of the car.

Use shaving foam, anti-fog additives

In addition to using the air conditioning system, the glass defroster function equipped on the car... some drivers also apply the method of using a dry towel, shaving foam or anti-fog additives to wipe each small area on the surface of the car glass, the side windows of the car. This method is quite complicated but also effective in helping the car glass not to condense.

Note,In addition to the above methods, when detecting that the car glass is foggy, the driver should not use a towel or paper to wipe the inside of the glass. This is both inconvenient and creates streaks on the glass, reducing visibility.
