Methods to defrost car windows in winter: 1. Use the car's defogging function to remove frost. After starting the car, turn on the air conditioning defogging function to blow away the frost on the windows; 2. Purchase a defogging spray. Spray the defogging agent on the inner surface of the window to prevent frost formation. One application of the defogging spray can prevent fogging for ten days; 3. If the frost is not too heavy, open the window slightly to allow air convection inside the car, which will also disperse the frost; 4. If frost forms while parked, rinse with warm water or start the car and turn on the hot air conditioning to blow on the windows for a while; 5. If frost forms while driving, wipe it off with a clean cloth or newspaper. When starting the car, slightly lower the two front windows to reduce the interior temperature. Once the car warms up, switch the mode to internal circulation, adjust the blower to hot air, and direct it to blow on the windows.

The most annoying thing in winter is frost on the car windows. I always start the car ten minutes early and turn on the heater. Remember to adjust the air vents to the defrost mode—the symbol is usually a fan-shaped icon. Also, don’t forget to press the rear window heating button; watching the frost lines slowly disappear is oddly satisfying. For frost outside, use a dedicated ice scraper with a plastic blade to avoid damaging the glass. If you’re in a hurry, pour lukewarm water (not hot water, as it may crack the glass) on the windshield and use the scraper—it’ll speed things up by half. Before parking, it’s important to open the windows to release interior moisture; otherwise, frost may form on the inside of the glass the next day, which is even more troublesome. On sunny days, take a moment to lift the wipers to prevent them from freezing to the glass.
