How to Deal with Foggy Windows While Driving?
2 Answers
Here are solutions for foggy windows while driving: 1. Use specialized anti-fog products. These products are available at auto accessory stores or online. Before each use, spray evenly on the windows and wipe clean to form a transparent protective film that prevents fogging. One application can last 10 to 15 days, but the downside is the higher cost. 2. Use dish soap with a dry cloth. Mix dish soap with water (ratio 1:6), apply evenly on the interior windows with a sponge, and wipe clean with a car towel after drying, leaving no watermarks. This method typically keeps windows fog-free for up to 20 hours. The principle is similar to using anti-fog spray, though slightly less effective, but it's a simple and economical alternative.
What annoys me most when driving is the foggy windshield in winter—blurred vision is so dangerous. Recently, I researched a three-step method: first, turn the air conditioning to maximum, adjust the airflow to the windshield, and remember to turn on the external circulation to vent out the moisture. Setting the temperature to around 22°C with warm air is ideal; cold air defogs quickly but gets too chilly over time. There’s also a folk remedy—mixing dish soap with water at a 1:10 ratio and wiping the glass, which keeps it fog-free for days. Before driving, remember to remove wet towels or clothes from the car—they’re the main culprits for fogging. If fog suddenly appears, don’t panic—turn on the hazard lights, pull over, and handle it safely first.
