What to Do When the Front Windshield Fogs Up?
2 Answers
If you notice that the fog inside the car is not too heavy, you can open the windows on both sides slightly to create a convection of air inside and outside the car. This will reduce the temperature difference and the fog will disappear. Almost all cars on the market have air conditioning vents located under the front windshield. Simply adjust the air conditioning to the appropriate setting to use the airflow from the air conditioning to defog the windshield.
As a commuter who drives to work frequently, my car's windshield tends to fog up in winter, mainly due to the condensation of warm air inside the car hitting the cold glass, which obstructs visibility. In such cases, my go-to method is to immediately turn on the air conditioning, switch to the defogging mode (the fan icon), and activate the external air circulation while increasing the fan speed. The fog usually clears within two to three minutes. On rainy summer days when the interior gets too humid, I also roll down the windows for a few seconds to ventilate, cool down, and reduce humidity to prevent fogging. Safety is paramount—never wipe the fog with your hands while driving, as it can be distracting. If necessary, pull over to handle the issue. Developing good habits like checking if the air filter is clogged, regularly cleaning the inside of the windshield, or using an anti-fog spray can minimize such hassles, especially for daily commuters like me, making life much easier.
