How to Solve Frosting on the Inside of Car Windows?
3 Answers
Solutions for frosting on the inside of car windows include turning on the external circulation to heat the glass, wiping with hot water, and using dish soap. Below are detailed steps for each method: 1. Turn on the external circulation to heat the glass: Activate the car's external circulation system, adjust the fan speed to level 4 or higher, and use the hot air mode to blow on the glass. It takes about three minutes to remove the frost from the car windows. 2. Wipe with hot water: Bring a bottle of hot water from home, pour it onto the car windows, and then wipe with a towel. 3. Use dish soap: Mix dish soap with water and apply the solution to the front windshield.
The most annoying thing in the morning is fogged or frosted windows. I usually start the car, turn on the heater, set the fan to maximum blowing at the windshield, and press the front defrost button. Remember to also turn on the AC switch because the compressor provides the best dehumidification effect. Wait for three to five minutes, and the fog will clear. It’s also very useful to keep a clean chamois cloth in the car for quick wiping in emergencies. Another trick is to turn off the heater before parking and open the windows to balance the interior and exterior temperatures, which helps prevent frost the next day. I’ve also tried spraying anti-fog spray on the inside of the glass, which works quite long-lasting, and it’s available at supermarkets for just a few dollars.
I always keep a defogging spray in my car—just spray and wipe to solve the problem, but opening windows for ventilation is the quickest in emergencies. Set the AC to external circulation mode, turn the temperature knob to the red zone, adjust the fan speed to medium, and most importantly, press the defogging button and AC button to let dry cold air dehumidify. Another budget-friendly method is wiping the glass with a mixture of dish soap and water, which can prevent fogging for half a day. In winter, I crack all four windows slightly before leaving the car to release moisture, reducing the chance of frost on the glass by 70-80%. Remember, never pour hot water on the windshield—the extreme temperature difference can cause it to crack!
