How to Solve the Problem of Blurred Car Glass in Humid Weather?
3 Answers
In humid weather, blurred car glass can be resolved using wipers and the air blowing system. Here are the detailed solutions: 1. Fog on the windshield: The fog on the windshield can be removed by turning on the wipers; if the glass is very dirty, spray glass cleaner several times, and the glass will become clean. Then, turn on the car's air blowing system and direct it towards the windshield. Blowing cold air for a few minutes will completely eliminate the fog on the windshield. 2. Fog on side windows: When the fog is severe, the side windows may also fog up. In this case, slightly opening and closing the windows can significantly reduce the fog, improving visibility outside. 3. Fog on rearview mirrors: Installing rain guards above the rearview mirrors and applying soapy water or anti-fog agents before driving can keep them clear for at least 1-2 days.
I've been driving for decades, and foggy windows on humid days are a common occurrence, which affects driving safety. When I start the car, the windows get covered in a layer of fog, making it hard to see anything. The most direct solution is to use the air conditioning defogging function—press the defog button, turn on the A/C and recirculation mode, and direct the airflow toward the windows. The fog usually clears in two to three minutes. In emergencies, keeping a dry towel handy to wipe the inside of the windows can help. But long-term prevention is more important. Before the rainy season, I apply anti-fog spray to the windows, which forms a waterproof film and works well. Also, keep the interior dry and avoid leaving wet items like umbrellas or water bottles inside, as high humidity worsens fogging. Using warm air can also defog, but cold air is more effective in summer. Remember not to open windows for ventilation during heavy rain, as water may seep in. These small tips become second nature with daily use, and forming a habit of checking window cleanliness prevents dust buildup from obstructing visibility. Safety always comes first—if visibility is poor, pull over immediately instead of pushing through.
As a new driver, I used to be quite scared when the windows got foggy on humid days. The immediate solution is to turn on the air conditioning defogger, increase the fan speed, and select the external circulation to dry out the moisture—this clears the windows quickly. Alternatively, simply wiping the glass works; I keep a microfiber cloth in the car to wipe the fog away with a few swipes when it appears. For prevention, avoid clutter in the car, keep it clean, and minimize opening windows to prevent moisture from entering. Balancing the temperature difference by using cold air in summer and warm air in winter is also effective. Practice a few times to familiarize yourself with the location of the car's control buttons to save time. Another useful tip I learned is to close the windows promptly after parking in the rainy season to reduce moisture buildup. These simple tips are easy to follow, safe, and hassle-free.
