How to Dissipate Fog Inside the Car When It Rains?
4 Answers
Methods to dissipate fog inside the car when it rains: 1. Locate the front window defogging mode, set the fan speed to high, turn on the AC switch, and adjust the temperature to the lowest setting; 2. Use the air conditioner's hot air to defog. If the car has just started, temporarily avoid turning on the air conditioner. Wait until the engine has warmed up for a few minutes, and the water temperature rises before starting the heating. Set the air volume to high and then activate the front window defogging mode; 3. Adjust the air conditioner temperature to heating, rotate the air direction switch to blow towards the glass, and the fog will disappear shortly, with very noticeable effects; 4. You can prepare a defogging spray. Before traveling, simply spray it evenly on the surface of the car window glass and wipe it clean with a dry towel.
Fogging in the car during rainy days is mainly caused by external humidity and temperature differences condensing on the windows. Having driven for over a decade, I immediately turn on the air conditioning's defogging function when encountering this situation—lowering the temperature and directing the airflow toward the windshield. It's also essential to switch to external air circulation to draw in dry air from outside. Keeping an anti-fog spray in the car and applying it to the glass periodically can prevent fogging. More importantly, develop good habits: close windows tightly when parking to prevent rainwater from seeping in; regularly clean carpets and seats to reduce moisture buildup inside the car. By consistently following these practices, fogging is significantly reduced, ensuring clear visibility and safer driving.
As an ordinary car owner who often drives in the city, I find fogging on rainy days quite annoying. I immediately turn on the air conditioning in cold mode to defog, adjusting the airflow to the highest setting directed at the windows. Anti-fog wipes or soapy water applied to the side mirrors and front windshield also work well. Keeping a silica gel desiccant pack on the dashboard helps absorb moisture. To reduce moisture sources: shake off the umbrella before getting in the car, and wrap wet shoes with absorbent mats. For daily parking, choose dry spots, minimize placing items like water cups inside, and maintain a clean interior environment. These simple methods have proven effective after multiple trials.
Fog is condensation formed when warm, humid air comes into contact with cold glass. During rainy weather, the humidity inside the car is high, and the window temperature is low. The best way to remove fog is by using the air conditioning's dehumidification function, with the mode set to external circulation to dry the air. Applying anti-fog spray to the glass reduces surface tension. Eliminate moisture sources: ensure doors and windows are well-sealed, and regularly wipe down the interior to prevent water accumulation.
