What to Do When the Outside of a Car's Windshield Fogs Up?
2 Answers
If the fogging is not severe, you can slightly open the windows on both sides to create a gap. This allows the air inside the car to circulate, gradually bringing the interior temperature closer to the outside temperature. When the front windshield is heavily fogged, press the defogger button to clear the fog and ensure clear driving visibility. Using a window defogging spray is a highly effective method for quickly removing fog in a short period of time.
I've been driving for years, and encountering fog on the outside of the car's windshield is a common occurrence, usually happening on rainy or cold days with high humidity, as the cold air outside condenses into water droplets when it meets the warm glass. Dealing with it isn't complicated: turn on the air conditioning, set it to cold air mode, and direct the airflow to the windshield; immediately use the wipers to wipe it, and the fog will clear. If the fog is heavy, you can crack the window slightly to ventilate and disperse the moisture, but don't open it too wide to avoid rain getting inside. Remember not to panic while driving—slow down first to ensure safety before taking action. Prevention is also key. Every time I wash my car, I make sure to clean the glass surface thoroughly to remove grease and dirt, which significantly reduces the chances of fogging. Maintaining clear visibility is crucial for driving safety—don't lose sight of the bigger picture over minor issues.
