Every winter, it's the same story. You open the shutters, and there… surprise: fogged-up windows, sometimes even slightly frosted, blurring your vision and giving the impression of persistent dampness. Wipe them clean? The fog returns. Air the room? It's not always enough. Yet, my grandmother never really had this problem. Her secret? A trick as simple as it is unexpected, which takes only four minutes… and makes all the difference.
Why does condensation form so easily in winter?
When it's cold outside and the indoor air is heated, humidity naturally condenses on cold surfaces. Windows are the first areas affected. Kitchens, bathrooms, and poorly ventilated bedrooms are particularly impacted because our daily activities (cooking, showering, breathing) release a lot of moisture into the air, often without us realizing it.
