How to Deal with Fogging on Car Windows?
2 Answers
Here are the methods to handle fogging on car windows: 1. Turn on the heater or air conditioner according to the external environment, which can help defog; at the same time, you can turn on the external circulation of the air conditioner and set the vents to defog mode, which will keep the interior from getting too cold and also help suppress window fogging. 2. Use anti-fog spray; car detailing shops usually carry anti-fog sprays. You can ask the staff to apply a layer during car washing, then wipe it clean. This will coat the glass with a protective film, making it less prone to fogging in rainy weather. However, anti-fog spray may blur vision, so avoid using it at night. 3. Open the windows to allow air circulation; when the windshield fogs up, roll down the window slightly to let outside air blow in, and the fog will dissipate quickly. However, it's best to park the car on the roadside first, as this method takes some time to work. 4. Wipe off the fog with a cloth; this method is time-consuming and labor-intensive, so it's not recommended. 5. Another lazy method is to wipe the windows with dish soap or soapy water, then rinse with clean water and dry them. This will prevent fogging, although the effect doesn't last long. Glycerin can also be used, but it's more expensive and less economical than dish soap or soapy water.
I've been driving for fifteen years and have the most experience dealing with foggy windows. When you get in the car, don't rush to close the windows for ventilation. Turning on the external circulation to let the moisture out works best. On rainy days, turn on the cold air and direct it toward the windshield, remember to press the defog button, and adjust the airflow downward to avoid your face. If the rear window fogs up, simply turn on the rear defroster, and it will clear up in a few minutes. Always keep a dry towel in the car for emergencies, but remember to open the windows for ventilation after wiping, or the fog will return quickly. In northern winters, I preheat the car in advance and wait until the engine warms up before turning on the heater to defog, so my hands won't freeze. The key is prevention—try not to drink hot beverages or spray perfume in the car, as high humidity makes fogging up especially easy.
