The home and garden experts at  have revealed that placing salt by windows can act as a natural dehumidifier.

During the colder months, the air in our homes tends to be warmer and more humid resulting in more moisture in the air. 

When the warm air from indoors comes into contact with the cold surface of the window, it can cause condensation to form on the glass. 

If left untreated, constant condensation could act as a breeding ground for mould to thrive. 

But salt can actually absorb moisture from the air, making it a great household item for combating condensation.

Placing a bowl of salt near your windows will allow the salt to absorb and draw in any surrounding moisture.

Less moisture in the air means that when the indoor air does come into contact with the cold glass, less condensation should form. 

Andy Ellis, home and garden expert at  said: “A constant build up of condensation in the home isn’t great and in some cases it can cause mould growth which can be dangerous for your family.

“Condensation forms when the warm air inside of your home comes into contact with the cold surface of windows. 

“Although some condensation is normal, you definitely don’t want too much of this in your home.

“Salt has the ability to naturally absorb moisture from the air and essentially dries it out so that when it does come in contact with the glass, there are less droplets of condensation that will form.”

He continued: “It’s a really easy trick that requires no effort at all. Simply fill a shallow bowl or a small jar with some salt – this can be table salt or rock salt.

“The amount you use will vary depending on the size of the window you’re placing it next to. Of course, generally speaking, the larger the window the more salt you’ll need, though usually one small bowl should be fine. 

“The same bowl of salt should last you a couple of days. You’ll know when it’s time to replace it because the salt will appear damp and will begin to clump together.”
