Mould is a sight no one wants to see in their home – it's not only gross-looking, but it can also pose serious health risks if left unchecked.
At times, it may seem like an insurmountable task to eliminate it, even if you've tried all the top 'fool-proof' methods such as white vinegar and mould sprays.
However, there's a German technique that costs nothing and will help reduce humidity in your home, preventing mould from gaining a foothold.
@naziaxhome posted a video where she mentioned that many people advise against opening your windows in winter because it's "too cold." But she, along with many others, begs to differ.

A Reddit user has shed light on the concept of 'Stossluften', which involves opening several windows for a brief period to create a draft - this could clear your home of condensation within minutes.
They wrote: "In Germany, we have a technique called 'Stossluften', or 'shock ventilation'.
"What that essentially means is that instead of leaving maybe one window open all day (which is a massive waste of energy), open several windows throughout the house for three minutes, creating a strong draft to replace most of the warm humid air inside the house with cold air from outside.
"A cool feature about cold air is that it can 'hold' less water vapour. If this relatively dry cold air enters your house, it warms up. Being warmer, it is suddenly capable of taking up some of the extra humidity from inside your house.
"This might sound a little weird at first but is advocated in schools and so on. I use that technique and it works. Do this several times a day and you should really see a change. Maybe get a device to show you the relative humidity inside your house."
Raymond Galvin, a researcher at the Universities of Aachen and Cambridge, echoed this when speaking to Politico: "The correct way to ventilate a home is to employ the Stossluften, or shock ventilation method.
"You open your windows completely for three minutes if it's windy, five to 10 minutes if it's not."
In the comments of the TikTok, someone wrote: "I have to do this in the morning to get fresh air in don't care how cold it is".
Another added: "Is this not normal??? I even have my back door open."
"Mine are open 365 days a year", somebody penned.
