How to deal with foggy glass when driving a car in the rain

(Baonghean.vn) - Car windows fogging up when driving in the rain is a fairly common phenomenon. Some simple ways below will help drivers quickly overcome this situation.

When driving in the rain, many windshields and car windows become foggy, reducing the driver's visibility and causing safety risks. This phenomenon occurs when the temperature and humidity inside and outside the car are large, causing condensation on the glass.

To remove fog from the glass, you need to dissolve the condensation. You can refer to the following methods:

Lowering the car windows helps balance the temperature

In case of light rain, the driver can lower the windows on both sides by about 5 - 10cm, and turn on the fan to circulate the air. The exchange of air inside and outside helps the windows return to normal; do not lower more than 10cm to avoid rain and dust entering the car.

Using glass drying system

Front and rear window heating systems are commonly equipped on today's car models. The front and rear windshield heating system buttons are usually located on the center console, close to the air conditioning system, with a separate symbol and when activated, an indicator light will turn on.

Normally, in vehicles with automatic air conditioning systems, the defroster will automatically turn on and off after a certain period of time. If the defroster does not turn off automatically, the user can turn this function off after the car windows are defrosted to optimize fuel and air conditioning.

When using the defroster function, the car windows must be closed. If even one window is not closed properly, the system will not work properly and fogging may still occur.

Turn on the fan with outside air intake mode

Turning on the fan and setting it to outside air intake mode also helps to balance the temperature inside and outside the car, avoiding condensation on the glass. This method should be done when the glass is just starting to fog up, or when the condensation has not yet formed on the windshield or rear window.

Use air conditioning system

Select the windshield air mode on the air conditioning system, adjust the air level and temperature appropriately because if it is too cold, it is easy to cause condensation on the outside of the glass.

Do not use air conditioning at hot temperatures to dry the condensation on the glass because condensation on the windshield is due to the temperature difference inside and outside the car.

*How to fix the problem of wipers not cleaning the glass

When driving in the rain, in addition to the phenomenon of foggy glass, we often encounter the situation where the wipers do not wipe cleanly on your viewing space, leaving blurred spots or water stains imprinted...

The solution is as follows:

- Add some specialized detergent to the windshield washer fluid tank to help clean and not leave streaks on your car's glass. Be careful not to use common detergents such as washing powder because they can cause the rubber wiper blade to deform.

- When drying the glass, do not dry at too high a temperature to avoid damaging the rubber wiper blade due to heat.

- Periodically check the wiper blades for deformation.

- Do not leave the car under strong sunlight to avoid deformation of the wiper blades.
