As the temperatures continue to drop, you may often find yourself cranking up the heat in a bid to keep warm and toasty this season. However, while keeping the cold out and blocking the chill, you may inadvertently create issues like condensation, foggy windows, or even mold.

Condensation is caused when warm air inside your home meets the cold surface of the glass, then cools quickly to form moisture droplets. Not only could this excess water cause mold spores but can make windows foggy.

Luckily, there is a common kitchen staple that can prevent condensation and mold. What’s more, this is found in most of our kitchens and only costs around $1. So what is this?

Leave baking soda on windowsills

According to experts, baking soda is the quick solution to preventing condensation and foggy windows. Besides being a staple for baking, this natural substance is excellent for soaking up and trapping excess moisture in the air.

So, if you place a small bowl of baking soda on windowsills this winter, this can essentially soak moisture that forms on the glass and reduce humidity levels.

In fact, this kitchen staple can be put to good use around the home and yard, and there are so many things you didn't know you could clean with baking soda.

Unlike many shop-bought products and sprays, baking soda is completely natural, non-toxic, and odor-free, which is much more eco-friendly. This is always ideal if you have children or pets running around in the home. Better still, you can pick up a box of baking soda for just under $1, saving you a fortune on buying expensive products.

So if you want to actually see out of your foggy windows, try this baking soda trick on your windowsills this winter.

Besides baking soda, there are far more easier and quick things you can do to prevent excess moisture from collecting on your windows. Firstly, it's recommended to crack open a window or door for at least 15 minutes each day to allow adequate ventilation and increase air flow. And if your room doesn't have a window, be sure to switch on exhaust fans, particularly in high- moisture areas such as bathrooms and kitchens.

However, if you do have serious condensation issues, one of the best dehumidifiers will be more effective. In addition, inspect your home for any leaks and repair leaky pipes, roofs, or faucets that could be the culprit for releasing excess moisture.

Just note that if you're contending with mold issues, it's always best to seek guidance from a professional mold removal service. Check out these 5 tell-tale signs that you need a dehumidifier right now.
