What to Do When the Car Fogs Up After Coming Out of an Underground Garage in Summer?

[DeEmery]

Don't rush to turn on the air conditioning for cooling. First, open all the windows to ventilate and speed up the warming of the front windshield. Once the front windshield warms up, the fog will disappear on its own. If the fog is on the inside, turn on the air conditioning with the AC cooling and set it to blow air on the front windshield to defog, while slightly opening the side windows. Related tips are as follows: 1. Using Air Conditioning to Defog: Using the air conditioning to defog is a common method. Turn on the cold air to blow on the glass, and the defogging effect is immediate. However, people inside the car will feel very cold, and if the humidity inside the car isn't removed, the fog will reappear on the glass soon. 2. Using Hot Air to Defog: Using hot air to defog is more effective than using cold air, but the effect takes longer to appear. Once the hot air dries the moisture inside the car, the glass won't fog up again for a long time. It's best to turn on the hot air while parked and then wipe the windshield with a cloth. Additionally, turning on the external circulation while driving can also help prevent fogging to some extent.
