How to Remove Fog on the Outside of Car Windows?
2 Answers
When the fog is light, open the car windows. When the temperature inside and outside the car becomes similar, the fog will dissipate. Turn on the car's cold air conditioning, and switch to hot air conditioning before driving. Activate the car's defogging function. Apply a mixture of dishwashing liquid and water or soapy water to the windows.
I often encounter fogging on the car windows while driving, especially on cold or rainy mornings when a layer of mist forms on the outside of the windshield, obstructing visibility. This situation is usually caused by a significant temperature difference, such as when it's cold outside and warm inside the car, causing water vapor to condense on the surface. My experience is to immediately activate the windshield wipers to wipe it off, which in most cases clears it instantly. If there is still residual fog, I switch the air conditioning to the windshield defogging mode, directing the airflow toward the outer glass, and adjust the temperature to cold or warm air as needed to eliminate the temperature difference. When the wipers are less effective, check if the glass is contaminated with oil or dirt. You can use a specialized glass cleaner to spray and scrub away the stubborn source of fog. It's best to regularly clean the windows after parking, such as using a soft cloth to dry moisture or applying an anti-fog spray as a preventive measure. The key is not to panic when fogging occurs on the road; find a safe place to stop and handle it rather than risking driving to ensure safety.
