How to Deal with Foggy Windshield When Using Air Conditioning?

[BriellaAnn]

Here are the solutions for dealing with foggy windshield when using air conditioning: 1. Use cold air from the AC: If the windshield becomes foggy, the fastest and most effective method is to immediately turn on the AC's cold air, increase the fan speed, and direct the cold air toward the windshield. Cold air rapidly lowers the windshield's temperature, eliminating the conditions for fog formation, making it quick and effective. However, prolonged use in cold winter temperatures can make the interior too chilly, so switch to warm air after the fog clears. 2. Use warm air from the AC: Warm air reduces the temperature difference between the inside and outside of the window, allowing fog to evaporate quickly. This method is more effective than using cold air and is ideal for use when starting the car in the morning. Once the fog clears, the windshield will remain clean while driving. 3. Open windows for airflow: If the fog is not too heavy, slightly opening the windows allows hot and cold air to circulate, reducing the temperature difference and clearing the fog. However, use this method cautiously in cold weather, rain, or when driving at high speeds. 4. Use anti-fog spray: Clean the windshield thoroughly and apply a professional anti-fog spray to form a liquid film. Once dry, wipe it clean with a towel to prevent fog formation. Alternatively, mix cleaning solutions like detergent, hand soap, body wash, or shampoo with water in a 1:6 ratio and apply it to the windshield. After drying, wipe off any residue with a clean cloth to achieve the same effect.
