As temperatures outside drop and frosts begin to form, many of us will be waking up in the morning to find our windows covered in a thin layer of water, as the warm air from our houses meets the cold air against the window and condensates.
Condensation on your windows isn't a huge deal on its own, but leaving the water untreated could result in bigger problems, as the damp conditions can make for the perfect breeding ground for mould.
But according to one cleaning expert, there is a way you can keep condensation at bay - and all you need is one 45p kitchen staple that many of us will already own.
Lynsey, who posts on TikTok under the username @lynsey_queenofclean, shared a video in which she explained her mum often has to deal with bad condensation on her windows, and said she "swears by" using a drop of washing up liquid to "create a barrier" on her windows that keeps water from sticking.
In the clip, she said: "We don't have any condensation in our house, it's a relatively new house, but my mum has an old house and she suffers with it quite a lot, and it's a problem for so many people.
"You need to wipe the water off every morning with a thick microfibre cloth, and open the window as well to let the window dry. You can get mould that starts appearing around the window frame, so just make a priority of every morning going around your house with your cloth.
"What you're going to need next is washing up liquid. You literally only need a tiny drop. This tip is very similar to putting shaving foam on a shower screen - you're creating a barrier which is going to stop the water from sticking on your windows.
"My mum swears by this and a couple of driving instructors messaged me and said this is what they do to stop cars from being wet inside in the morning."
The cleaning guru then simply put a drop of washing up liquid on her cloth and used it to wipe down her window, rubbing the liquid across the glass until it covered the entire pane.
Most of us will have washing up liquid in the house already, but if you need to dash out to buy some, you can pick it up for as little as 45p from Tesco.
Some commenters were unsure whether the tip would work as it seemed to leave "smudges" on the glass, but others said they had tried it themselves and claimed it worked wonders.
One person asked: "But are the windows not all smudgy then?"
But another said: "It definitely works, I did it yesterday!"
While a third added: "It works. I do this each week to keep on top of it. I had my own cleaning business and used to make my customer baffled when their bathroom mirror."
Lynsey later returned to the comments of her video to insist that the window will not be left with smears on the glass, as the small amount of washing up liquid used should spread out thinly enough to be almost nonexistent.
