How to Deal with Foggy Windows at Home?
3 Answers
On cold winter days, we often close the indoor window panes and turn on the heating or light a fire to provide the warmth we need. However, after a while, when we look out the window, we find it covered in mist, which affects the view and seems like an endless autumn scene. This often happens when you wake up in the morning. Prepare a towel, clean it with water to remove dust; this works better. Use a detergent (or other cleaning agents like soap, etc.), mix the detergent with water in a basin in a certain proportion, then rub the towel in the water, wring it out slightly, and use it to wipe the glass. This not only removes the fog but also effectively prevents it from forming again for some time. Now, enjoy the clean glass.
I find that when condensation forms on the windows at home, it's usually due to high humidity and temperature differences between indoors and outdoors, especially common in winter or rainy weather. I first use a clean, soft cloth to wipe away the water droplets, or gently wipe with newspaper because it has good absorbency and leaves no streaks. Then, I open the windows for a few minutes to let fresh air circulate and reduce humidity. If the weather is bad, I turn on a fan indoors and direct it towards the windows to disperse the fog. Usually, I pay attention to maintaining a balanced room temperature to avoid excessive heating that could create a larger temperature difference. Additionally, I regularly check the window seals and temporarily patch any cracks with tape to prevent moisture intrusion. In the long run, buying a small dehumidifier is quite effective—placing it near the window helps absorb moisture efficiently, preventing the glass from fogging up again and protecting furniture from the risk of dampness. Finally, here's a handy life hack: applying a diluted solution of white vinegar or dish soap on the glass forms an anti-fog film once dried, which is simple and convenient.
My car windows are fogging up, and I believe this issue needs to be handled properly to avoid wasting energy. The root cause lies in moisture accumulation. My priority is to open the windows to allow air circulation—even just a few minutes can make a noticeable difference, and it also reduces the electricity consumption from using the air conditioner. Using a fan to assist with airflow is quite efficient as well, preventing the fog from lingering too long and damaging the glass surface. With environmental considerations in mind, I prefer making my own dehumidifying tools: small bags filled with silica gel or quicklime placed on the windowsill can naturally absorb moisture without causing pollution, and they can be reused after drying in the sun. It’s important to develop good habits, such as turning on the exhaust fan while cooking or showering to reduce indoor humidity, and checking for drafts around doors and windows, adding weatherstripping if necessary. If the fogging is severe enough to impair visibility and pose a safety hazard at home, I recommend cleaning it promptly to prevent tripping or falls. In short, these simple actions can help maintain a comfortable environment.
