How to Deal with Foggy Side Windows?

[Madison]

Use the air conditioner to remove the fog by blowing air. There are two methods: using cold air and using hot air. This can quickly blow away the fog and is suitable for use on rainy summer days. Some car models are equipped with a rear window electric heating function. When cleaning, be sure to wipe along the direction of the heating wires to avoid damaging them.

As an experienced driver with years of driving, I know not to panic when the windows fog up and to deal with it immediately for safety. The most reliable method is to start the engine, then press the AUTO button on the air conditioning to direct the airflow to the front windshield; most cars have a defogging mode, usually indicated by a fan-shaped arrow icon. If the fogging is particularly severe, slightly open a window to ventilate and expel moisture while maintaining a steady speed. The cause is usually a large temperature difference between inside and outside combined with exhaled moisture condensing, especially after rain or in winter. Never use a cloth to wipe while driving, as it's unsafe to move around. I usually keep a bottle of anti-fog spray in the car; after cleaning the glass, spraying it on can prevent fogging for several days. In short, don't push through; handle it thoroughly when parked.
