How to Remove Fog Inside a Car?
2 Answers
Methods to remove car fog are as follows: 1. Use a cloth with highly concentrated dishwashing liquid to wipe the glass (inside the car), which can prevent fogging for about 24 hours. 2. Purchase anti-fog products from car accessory stores or online and apply them, typically lasting about 24 hours. 3. Use the car's equipment by turning up the heating switch (adjust according to your own comfort), then set the air outlet direction to the front windshield, and turn on the A/C switch. 4. Turn on the automatic air conditioning and set the mode switch to the defogging position. At this time, the air conditioning automatically switches to external circulation, allowing fresh air from outside to enter the cabin.
When there is fog inside the car, I usually turn on the car's defogging function. This feature is quite practical—adjust the airflow direction to blow toward the front windshield, turn on the external circulation mode, and use either hot or cold air depending on the weather. Use cold air in hot weather and warm air in winter, and the fog will dissipate quickly. Fog forms mainly due to high humidity inside the car and temperature differences, so it's important to ventilate and clean the windows regularly to prevent it in advance. Over the years of driving, I've encountered foggy conditions many times, especially on rainy days or early mornings when the windshield gets blurry and hard to see through—this can be a safety hazard and lead to accidents. I recommend checking the air filter regularly; keeping it clean improves defogging efficiency. If the fog is particularly heavy, you can crack the window slightly to let in some air, but don’t open it fully to avoid discomfort from cold drafts. With these methods, long drives become much safer and more comfortable.
