Foggy car windshields is a common problem faced by drivers. When fog forms on the car windshield, it hinders visibility, increases the risk of accidents, and reduces driving comfort. Fog on the car windshield occurs when the water vapor in the air inside the car condenses on the colder glass surface. Although it may seem like a minor issue, fog on the car windshield can be highly disruptive and potentially hazardous to safety.
In this TransTRACK article, we will delve deep into the causes of fog formation on car windshields, including temperature differences, air humidity, poor air circulation, and issues with the car’s cooling or heating system. We will also provide practical and effective solutions to tackle fog on car windshields, such as using the car’s AC, utilizing defoggers, adjusting the temperature inside the car, improving air circulation, opening car windows, and wiping foggy windshields.
Causes of Foggy Car Windshields
Foggy car windshields occur when the water vapor in the air inside the car condenses into small water droplets on the colder glass surface. This typically happens when there is a temperature and humidity difference between the air inside the car and the outside air. Here is a more in-depth explanation of the causes of foggy car windshields:
Temperature Differences
One of the main causes of fog on car windshields is the temperature difference between the air inside the car and the outside air. The air inside the car is generally warmer due to the influence of the heater or passengers’ body heat. When the warm air comes into contact with the cold glass surface, such as in the morning when the outside air temperature is lower, the water vapor in the air immediately condenses and forms a layer of fog on the glass.
Air Humidity
Air humidity also plays a crucial role in the formation of fog on car windshields. If the air humidity inside the car is high, the amount of water vapor contained in the air is also high. When the humid air inside the car comes into contact with the colder glass surface, the water vapor condenses and forms fog on the windshield. Humidity inside the car can increase due to factors such as humid weather, passengers’ body humidity, and the presence of wet objects inside the car.
Poor Air Circulation
Poor air circulation inside the car can exacerbate the fogging problem on the windshield. When the air inside the car doesn’t flow properly, the water vapor generated by passengers or activities inside the car cannot disperse effectively. The humidity and water vapor get trapped around the glass surface, thereby increasing the risk of fog formation.
Dysfunctional Cooling and Heating Systems
Malfunctioning cooling and heating systems in cars can also cause fogging on the windshield. If the cooling system (AC) doesn’t function optimally, the temperature inside the car can become too high, increasing the air humidity and causing fog. Conversely, if the heating system doesn’t work properly, the temperature inside the car can become too low, resulting in fog when there’s a temperature difference with the outside air.
Poor Quality Windshield Glass
The quality of the car windshield can also affect fog tendencies. Car windshields that lack anti-fog coatings or have damaged or scratched coatings may be more susceptible to fog formation. Anti-fog coatings typically help prevent or reduce the condensation of water vapor on the glass surface.
To address fog on car windshields, it is important to maintain a balance of temperature and humidity inside the car, as well as ensure good air circulation.

How to Deal with Foggy Car Windshields
To address the issue of fog on car windshields, here are some steps that can be taken:
Turn on the Car’s AC
Turning on the car’s AC can help combat fog on the windshield. The AC works by removing moisture from the air inside the car. By activating the AC, the air entering the car will be drier, thus helping to reduce fog on the glass. Make sure the AC is functioning properly and adjust the AC temperature to your preference.
Utilize the Defogger
Most cars are equipped with a defogger, which is a specialized air vent to address foggy car windshields. The defogger directs warm air directly onto the glass surface, helping to dry the fog and expedite its removal. Activate the defogger for both the front and rear windshields, and adjust the speed and temperature of the air as needed.
Lower the Cabin Temperature
Foggy car windshields generally occur when the temperature inside the car is higher than the outside temperature. By lowering the temperature inside the car cabin, the temperature difference with the outside air decreases, reducing the risk of fog on the glass. Adjust the temperature on your car’s cooling or heating system to a lower setting.
Recirculate the Air
Using the recirculation option in your car can help reduce fog on the windshield. This option directs air from within the car without drawing in outside air. By not allowing outside air to enter, the humidity inside the car remains stable, reducing the risk of fog on the glass.
Open Car Windows
Opening car windows slightly can help improve air circulation inside the car. By allowing outside air to enter and flow around the car cabin, the humidity inside the car can decrease. Make sure to open the windows slightly when the outside conditions are not too humid or cold, to maintain a comfortable temperature inside the car.
Wipe the Foggy Car Windshields
If fog still forms on the car windshield, you can wipe it away using a soft cloth or dry tissue. Gently rub the glass until the fog disappears. Ensure that the cloth or tissue used is clean and doesn’t leave any fibers on the glass. You can also use specific anti-fog products available in the market to help prevent the formation of fog again.
It is important to note that preventing fog on the car windshield is also crucial. Ensure good air circulation within the car, avoid bringing in wet items or adding humidity inside the car, and periodically check the car’s cooling and heating systems to ensure they are functioning properly.
