What to Do When the Front Windshield Fogging Can't Be Blown Away?
2 Answers
If the front windshield fogging can't be blown away, you can wipe off the fog with a towel or use the window convection method to remove fog. Here are the specific details: 1. Wipe off the fog with a towel: If you want to wipe off the fog with a towel, it can only be done when the vehicle is stationary; you cannot wipe the glass while driving. 2. Window convection to remove fog: If the fog is not too heavy, you can open a gap in the windows on both sides to allow air convection inside the car. As the interior temperature gradually approaches the outside temperature, the fog will dissipate. The advantage is that it can achieve the effect of turning on the air conditioning without increasing fuel consumption. However, this method is not suitable in all situations, such as during cold winters or rainy days.
I have experience with this issue. When the car windows are fogged up and won't clear, don't rush to hit the road—safety first. You need to check the air conditioning system: First, confirm whether the defogging mode is activated (usually indicated by a fan-shaped icon) and if the airflow is set to maximum. Sometimes simply turning on the heater isn't enough; you need to turn on the air conditioning (AC) to dehumidify. In winter, if the fog doesn't clear after five minutes of hot air circulation, try using cold air for quick defogging. Also, check if the air filter is clogged with dust—last time I encountered this issue, replacing the filter made an immediate difference. Aging window seals can also allow external moisture to seep in, especially in older cars. If all else fails, use a defogging spray as an emergency solution, which you can find at any supermarket.
