A Hack to Stop Window Condensation
TikTok user @blooms_abode posted a quick solution to control mold growth around windows.
The hack starts by fully opening window curtains and blinds to allow complete access. Next, leave a jar of bicarbonate soda “bicarb” on the windowsill to absorb moisture. Every two weeks, use a mold spray and cleaning rag to run along the window to clean off any growth.
And that’s it!

Causes of Condensation in Windows
Condensation on windows happens when warm, moist air comes into contact with a cold surface, like a window pane. The air cools down, and the moisture in it turns into tiny water droplets, which is what you see on the glass.
This is especially common in colder months when indoor air is warmer and more humid compared to the chilly outside air. It can also occur if there’s a lot of moisture in your home—think cooking, showering, or even plants releasing water vapor. If the humidity inside your house is too high, it makes it more likely for condensation to form, even when your windows are closed.
Is Mold on Windows Dangerous?
Mold on windows can indeed be a concern, especially if left unchecked. While it might start as a small patch, mold can spread to other areas and release spores into the air, which isn’t ideal for indoor air quality.
For some people, especially those with allergies, asthma, or compromised immune systems, exposure to mold spores can lead to symptoms like coughing, sneezing, eye irritation, or even respiratory issues. Even if you’re not sensitive to mold, it’s still a good idea to clean it up as soon as you spot it, since it can damage surfaces over time and lead to staining.
Keeping your windows dry and controlling indoor humidity can help prevent mold from forming in the first place.
