The calendar winter has recently arrived. It's high time to put a plate or saucer with table salt on the windowsill.
But for what purpose should this action be performed?
The answer is simple: to combat condensation on the window.
Why do windows fog up in winter?
In the cold season, the window glass is the “border” between the street, where it is frosty, and the room, where it is quite warm.
This temperature difference is what causes the window to fog up: warm air comes into contact with a cold surface.
The problem can be solved by ventilation: this procedure helps to reduce the humidity in the room, and the glass stops fogging up.
However, in winter, for obvious reasons, people are reluctant to open windows.
In such a situation, salt will come to the rescue.
Why put a plate of salt on the windowsill
The bulk product is a good sorbent and “drying agent”.
Salt absorbs excess moisture, thereby helping to combat condensation. In other words, no water droplets appear on the window.
Sodium chloride poured into the plate should be changed periodically. The reason for replacing the product is its excessive moisture, as well as the appearance of lumps in it.
For reference
Table salt is a food product that is colorless crystals.
