The salt bowl trick in rooms with high humidity, such as the kitchen or bathroomis a classic if you go on vacation or to live in England or Scotland. A custom that has been exported to the United States and Canada, but can also be seen in Spain. What is it for? Is it effective? Well the truth is that not too much…
There are many homemade tricks at home. They come from popular wisdom, which is sometimes wise, but other times it has no scientific basis.
People put a salt bowl next to a window in winter, so that it absorbs moisture and does not condense on the glasswhich produces mold and humidity that spoils the wooden window frames. Does it really work?
The trick with the bowl of salt in the window, it’s not such a trick
The condensation of the air does not have much to do with the ambient temperature. That is, it can occur both in winter and summer, although it is more common when it is cold.
Condensation occurs when There is a difference between the air temperature and the dew point temperature.. This is the name given to the temperature at which air can no longer contain water vapor.
If the ambient temperature drops below the dew point, water vapor condenses. When it hits a window, water drops slide down the glass and fall onto the frame. This water can cause moldhumidity or oxidation. That is why you have to prevent the water from condensing.
Tradition says that salt absorbs moisture from the airand that prevents the water vapor from condensing. That is why a bowl of salt is placed near the windows. What does science say about it?
According to documents Thermopedia, via IFL Science, It is true that salt absorbs humidity from the environment. So this salt in the window trick has a scientific basis, surely obtained through observation.
The problem is that salt requires a lot humidity so that it begins to absorb it effectively. According to Thermopedia, around 75% humidity in the air. Very few houses have such humidity, the normal thing is that it varies between 30 and 60%. Although on very humid days, it can reach 70%. It can also accumulate if you cook with a lot of steam, for example in a pressure cooker.
The conclusion is that, indeed, the salt It absorbs moisture, but only when there is a lot of it. 90% of the days, it doesn’t do much good..
If you want to avoid condensation, It is much more practical to open the windows for a whileso that the air can flow. The air flow removes vapor from the water. Or use air conditioning, or a dehumidifier.
In any case, Putting a bowl of salt next to a window doesn’t hurt anyone.and in extreme cases of humidity it is useful, so nothing happens if you have that habit.
