Why Does the Car Window Freeze from the Inside in Winter?
2 Answers
Reasons for car windows freezing from the inside in winter: Residual heat inside the car causes the temperature of the car glass to be higher than the outside. If the external temperature is too low or it snows, the snow falling on the glass will melt first. During the melting process, the temperature inside the car gradually drops to match the outside temperature, and the melted snow on the glass begins to freeze. Once frozen, the falling snow no longer melts. The moisture in the car glass will solidify into ice beads, forming frost on the glass. Solutions for frozen car windows: 1. Use a bank card or a hard plastic card to scrape the ice, being careful not to apply too much force to avoid scratching the glass; 2. After using the car the previous day, do not leave immediately. Find a way to dissipate the residual heat inside the car.
My car windows freeze up inside during winter because the humidity inside the car is too high. In the morning when I drive, I can immediately see the frost patterns on the glass, which is quite troublesome. The main causes are exhaled moisture, rain or snow on clothes, or wet items left inside the car. After parking, if I don’t allow air to circulate, the moisture accumulates. When the temperature drops, it turns from water vapor into tiny droplets and then freezes into ice. I’ve tried a few methods and found prevention quite simple: before getting out of the car, open the windows for about three minutes to let the air exchange, or use an anti-fog agent to wipe the glass. This reduces humidity and makes it less likely to freeze. Before driving, check to ensure clear visibility to avoid accidents from poor sightlines. It’s also a good habit to avoid piling wet items in the car. In short, the key is to keep the interior environment drier, saving the hassle of scraping ice in the morning.
