What to do if the glass is foggy?

Here are some related introductions on how to deal with foggy glass: 1. Clean with a plastic brush: Use a new plastic brush for cleaning. Soak the brush completely in water and then wipe the glass directly. The plastic brush has strong cleaning power and is long enough to reach the outer side of the glass, making it easy to remove dust. Additionally, this type of plastic brush is easy to disassemble and clean. If the glass is not thoroughly cleaned, you can also add some detergent to the water to wipe the glass, then rinse it with clean water. 2. Wipe with a wet cloth: First, simply wipe the glass with a wet cloth. Then, pour a little liquor onto a dry cloth and wipe the obvious stains on the glass with slightly more force. If you don't have liquor at home, you can also mix shampoo with a small amount of water, stir well, soak a cloth in the mixture, and wipe the windows. Then, use a clean cloth to remove the water stains, and the entire glass will be bright and clean. 3. Remove dust with old newspapers: The simplest way to remove dust from glass is to use old newspapers. If you have unused newspapers at home, don't throw them away. You can wet the unused newspapers and use them to scrub stains on the glass. Newspapers can effectively remove dust and make the glass clean. 4. Wipe with onion: You can use fresh onions to wipe the glass, making it clean and bright. You can also use baking soda mixed with water to scrub the glass. The key is to quickly wipe off the water stains with a dry towel while the glass is still wet.
I'm used to using the A/C's cold air to quickly defog. Turn on the A/C button, set it to external circulation, and blow cold air toward the windshield—the fog clears in seconds. If it's too cold in winter, you can switch to warm air for defogging, but you'll have to endure the fog worsening for the first few dozen seconds. When there are many people in the car and the breathing humidity is high, it's best to open the windows in advance to allow air circulation and prevent fogging. I always keep a chamois cloth in my car to wipe the glass anytime—it works quickly but doesn't last long. Before parking, I always turn off the heater and open the windows to ventilate, so the glass won't have condensation the next day. With more rain this month, I've found that wiping the glass with a mix of dish soap and water can prevent fogging for two to three weeks.
I find the car defogging button super handy. There's a fan-shaped icon on the center console. When pressed, the AC automatically increases airflow to the windshield, perfect for sudden fogging while driving. Just remember to set the temperature a few degrees higher than outside to prevent re-fogging from temperature differences. For rear window fogging, press the rectangular button with heating wires. Newer models even allow voice temperature control - just say 'increase by two degrees'. I use anti-fog spray on windows every two months, making sure to wipe it evenly after application. Avoid leaving wet umbrellas in the car, and immediately absorb any water on floor mats. Sunny day ventilation is crucial - letting moisture evaporate prevents fogging.
My trick is prevention first. Shake off rain and snow from shoes before getting in the car, and never place wet coats on the seats. Keep the air circulation on external mode with fan speed at level 2 while driving. When washing the car, specifically instruct to clean the oil stains on the inside of the windshield, as fingerprint residues here easily cause fogging. If the glass appears white on rainy days, turn on the A/C cold air for five seconds to fix it. When temporarily parked, leave a slight window gap; closing the door too quickly can trap moisture and cause fogging. I've often heard people say applying soapy water prevents fog, but after trying three times, the effect wasn't reliable. Recently, I switched to anti-fog wipes, which are quite convenient.
