I keep mould and condensation off my windowsill with a £2 item every kitchen already has

Clearing condensation on a window can feel like a never-ending task in winter, but I have discovered there is an effective way to keep moisture off the glass without wiping it every day. Mould is often a big problem during the colder months, but I did not really consider it a serious issue until last month, when I noticed some green spots along my kitchen windowsill.

After some investigation, it turned out it was the beginning of some mould growth, and it was quickly spreading onto the wall and almost reaching a nearby wooden shelf.I do a deep clean of my kitchen at least once a week, so I was shocked at how fast the mould had spread unnoticed, and if it had been left any later, it could have cost me hundreds of pounds in damage. Windows can become the perfect breeding ground for mould spores at this time of year, thanks to condensation, which is when the humid air inside a home touches a very cold surface and releases all the moisture.

Condensation causes windows to stay damp for long periods of time and the lingering moisture will encourage mould to begin growing at an alarming rate.

If mould is out of sight in a corner, it can rot a windowsill, get underneath wallpaper and can become much harder to repair without having to call in a professional.

I am grateful I caught the mould problem early and now understand how important it is to wipe condensation from windows daily, though it is not always realistic during busy mornings.

However, I have now discovered a really simple way to keep condensation off my windows and now all I do is take a few seconds to place a bowl of salt on my windowsill.

Salt is super absorbent and can take moisture out of the air which means it will get rid of any humidity before it can turn into condensation.

How to use a bowl of salt to keep condensation and mould out of your home

All I did was buy a big 1.5kg bag of cooking salt, which cost less than £2, and reuse an old bowl that had previously been a candle holder.

I fill the bowl with salt and check it every morning. Once it becomes clumpy, it means the salt has absorbed too much moisture, so I rinse the bowl under the tap, dry it, and refill it.

It only takes a few seconds to refill the bowl, and it has kept my kitchen windows dry and the surrounding area mould-free. It is really easy to do so, I have also started placing salt on my bedroom and living room windows.

However, I noticed condensation still appears in very humid areas of the home, such as the bathroom and where I dry laundry.

In those areas, instead of using salt, I simply open the window for 10 minutes each day to let fresh air in and it helps get rid of the excess moisture.

Winter is the worst time for mould, but it's now been over a month since using the salt and ventilation method, and there has not been any new spotty mould stains around my home.
