Humid weather, how to deal with foggy car windows

Important notes when handling foggy car windows

Experts recommend that when the car windows are foggy due to steam, drivers should not use their hands, towels, or tissues to wipe the windows. This is not only inconvenient but can also create streaks on the glass, causing discomfort and affecting visibility, especially at night. Instead, methods such as drying the windows, turning on the air conditioner, or using a fan should be applied to ensure safety and effectiveness.

With headlights and taillights, if there is condensation and it does not evaporate after about half an hour of turning on the lights, it must be brought to the workshop to be checked and the gap in the lampshade that causes condensation must be treated.

In humid weather, insects and mice also like to go to the engine compartment, which is a warm and dry place to take shelter, so car owners need to check the engine compartment once a week to see if there are any strange marks or signs of water accumulation at the battery contact points and electrical system.

In humid, drizzly weather, it is best to find a dry and covered parking space to protect the car from corrosion and oxidation in the air. If you have to park outdoors, the car owner should carefully prepare an additional tarpaulin to cover the car.

How to deal with foggy car windows due to humid weather?

1. Lower the car window to balance the temperature

One of the easiest ways to deal with foggy car windows when it is raining or cold is to roll down the windows. This helps to equalize the temperature inside and outside the car, minimizing the accumulation of moisture on the glass. However, this method has the disadvantage that it takes a long time for the moisture to completely disappear. Especially in heavy rain, rolling down the windows can be inconvenient and impractical.

2. Use the glass drying function

Most modern cars are equipped with a windshield defroster. When the car windows become foggy due to condensation, the driver simply activates this mode via a button on the dashboard. This is the quickest and most effective solution to fix foggy windows, especially when driving in bad weather conditions. However, some older cars may not be equipped with this feature.

3. Use fan and outside air intake mode

The driver can use the fan in combination with the outside air intake mode. By adjusting the air direction towards the windshield, the fan will quickly blow away the water vapor on the glass. This method also helps reduce the temperature difference between the inside and outside of the car, preventing the glass from fogging up again.

4. Turn on the air conditioner to remove moisture.

Turning on the air conditioner is another effective way to deal with foggy car windows. When the windows are foggy from the inside, the driver should turn on the air conditioner in cold mode combined with the fan. This not only helps reduce the temperature in the car but also absorbs moisture, helping the windows quickly return to a transparent state. Note, it is recommended to use the internal air intake mode to prevent moisture from outside from entering the cabin.

Do not set the air conditioner to warm mode because the water vapor will not evaporate but instead condense more seriously due to the temperature difference. At the same time, activate the glass defrosting function (if equipped) to help dry the glass. The glass defrosting function activates the fan to blow strongly on the glass, helping to dry the car compartment.
