How to Solve Fog on the Car Windshield in Winter?
2 Answers
The methods to solve fog on the car windshield in winter are: 1. Open the car window; 2. Use defogging spray; 3. Turn on the air conditioning warm air; 4. Activate the car's defogging function; 5. Apply a mixture of dish soap and water or soapy water to the window; 6. Place a dehumidifier box inside the car; 7. Wipe with a towel. The reason for car fogging is: There is a temperature difference between the inside and outside of the car, with the cabin temperature being higher than the outside, causing moisture inside the cabin to condense on the inner windshield and form fog. The functions of car glass are: 1. Shelter from wind and rain, sound insulation and noise reduction; 2. Reduce wind resistance and guide airflow; 3. Protect the personal safety of passengers in the car.
Fogging on the car's front windshield in winter is mainly caused by the conflict between high interior humidity and the cold external glass. Having driven for several years, I'm accustomed to such minor issues. First, start the car and set the air conditioning to defog mode—usually indicated by a fan-shaped icon on the AC panel—and direct the airflow toward the windshield. Set the temperature higher, around 20°C or above, and turn the fan to maximum for a while. If not in a hurry, opening the windows for a few seconds to exchange air also helps, but close them quickly to avoid letting cold air in. For long-term prevention, check the cabin air filter and replace it if dirty to keep the air drier and reduce fogging. Avoid leaving wet items like umbrellas or damp clothes inside, as they increase humidity. In emergencies, keep a dry cloth handy to wipe the glass, but never do so while driving—safety comes first. Remember, act quickly, as blurred visibility can easily lead to accidents.
