It is particularly effective in damp rooms such as bathrooms or kitchens. Older or single-glazed windows also benefit significantly. In very cold weather, it greatly reduces condensation upon waking.
Small mistakes to avoid
- Applying too much foam: a very thin layer is more than enough.
- Use a lint-free cloth, which may leave marks.
- Test directly on tinted or treated windows without prior testing.
- A test on an inconspicuous corner is always recommended before treating the entire surface.
How long does it last?
Generally, the effect lasts between two and four weeks, depending on the room's humidity level. As soon as you notice the condensation reappearing more quickly, simply repeat the process.
To further enhance efficiency
This tip works very well on its own, but it is even more effective if you remember to ventilate for a few minutes each day, even in winter, and to limit sources of excessive humidity in certain rooms.
An economical and clever solution
Compared to electrical appliances or specialized products, this method is almost free and consumes no energy. A smart, economical, and easy-to-adopt daily habit.
Sometimes, the most effective solutions are those that our grandmothers already knew by heart.
