Severe water vapor in the window can be treated by glass water treatment, window cooling or window sealing. You can dry the water vapor on the window with a dry rag first, and then spray glass water, which can effectively prevent water vapor. You can also open windows for ventilation, so that the indoor temperature and humidity are the same as those outside, and you can also seal the windows to prevent water vapor problems.

In the morning, there was a layer of ice on the car glass. You can clean the car window with a little hard object or directly by hand, but you must never clean the car window with hot water, which will damage the car paint and even lead to the glass bursting in serious cases. You can't deice with cold water, which will also damage the paint or glass, and may also lead to more serious icing.
Most of the windows freeze in winter because the temperature inside the car is higher than the outdoor temperature after parking, which leads to the snow falling on the glass, melting first and then freezing. Turn on the air conditioner for a while before turning off the fire, or lock the car after the temperature inside the car is the same as that outside, which can effectively prevent the window from freezing. It is also effective to put clothes in the car on snowy days, or to pad the window with plastic sheets, newspapers, etc. Secure with tape.
