Why doesn't the mirror in the hotel bathroom fog after taking a shower?

This is because water will slowly turn into steam at room temperature and diffuse into the air. The steam in the bathroom will liquefy when it meets the cold glass to form white gas, which is what you call fog. After opening the window, the air circulates and the white gas is heated and evaporated.

The secret of simply eliminating glass fog: 1. Apply with dry soap and wipe with a dry cloth. 2. Wipe the cloth with 90% alcohol. Drop a few drops of shampoo on a sponge or cotton cloth. All three methods can prevent the glass from fogging.

The fog on the mirror is liquefied by the water vapor in the indoor air and meets the mirror with lower temperature. The mirrors in the bathroom are mainly divided into ordinary mirrors and anti-fog mirrors. Anti-fog mirrors are divided into coated anti-fog mirrors and electric anti-fog mirrors. The former prevents the formation of fog layer by coating micropores. The latter increases the humidity of the mirror surface by electric heating, and the fog evaporates quickly, so no fog layer is formed. Of course, the latter is more expensive.

There are electric foggers, coating foggers, and foggers are very expensive. Usually in cold or bathing, due to the difference between indoor temperature and mirror, the mirror will be covered with a layer of fog, which will affect the use. For example, you can rub some soap with your hands before taking a shower. After foaming, apply soap bubbles to the mirror surface. If you don't wash it, the bathtub won't fog. Of course, it is not too late to put it in the bathtub. This is the simplest and most effective method.

Before taking a bath, apply a layer of soap where you don't want him to fog. So he won't get foggy, and even if you bathe there with water, you won't get wet.
