Solutions for a frequently fogging car windshield: 1. Turn on the hot air blower and switch the air conditioning to external circulation mode, adjusting the vents to defogging mode; 2. Use anti-fog spray, but avoid it at night as it may blur visibility; 3. Open the windows slightly to allow outside air to circulate inside, which will quickly dissipate the fog; 4. Use a cloth to wipe the windshield if opening windows is not an option due to cold or rain; 5. Apply dish soap or soapy water, then rinse and dry with clean water to prevent further fogging.
It's quite annoying when the windshield fogs up while driving, a situation I often encounter, mostly due to cold or rainy weather causing a significant temperature difference between the inside and outside of the car, leading to moisture condensation on the glass. The solution is simple: right after starting the car, turn on the AC button to direct cold air straight at the windshield and switch to the external air circulation mode. This allows dry air to quickly absorb the moisture. In winter, using warm air to blow on the glass works similarly. Keeping a defogging spray handy, applying it to the inside of the glass and wiping it clean can prevent fogging for about a week. Cleaning the glass is also important, as dirt can worsen fogging. Make it a habit to activate the defogging function as soon as you get in the car, ensuring clear visibility before starting, and don't let fog compromise safety. For prevention, minimize wet items in the car, keep windows closed on rainy days, and regularly check the air conditioning filter.
