No need for complicated devices or expensive products. The trick relies on something you most likely already have in your bathroom: shaving foam. Yes, the kind used for shaving. When applied correctly, it leaves an invisible film on the glass that limits condensation.
What you need (spoiler: almost nothing)
To test this method, there's no need to rush to the store. You simply need:
- a classic shaving foam (avoid gels),
- A clean, dry cloth.
That's all. No mixing, no special tools, no complicated preparation.
The 4-minute express method
Here's how to proceed, step by step, in the correct order:
- Clean the glass quickly if necessary to remove dust or streaks, then make sure it is completely dry.
- Place a small dab of shaving foam on a cloth or directly onto the glass.
- Spread it over the entire surface with circular motions, without pressing excessively.
- Wipe immediately with a dry cloth until the glass is completely transparent.
Once the operation is complete, no visible trace remains, but the protection is firmly in place.
Why it works so well
Shaving foam contains surfactants that create a thin barrier on the glass. This layer prevents moisture from easily adhering to the surface. The result: less fogging, fewer droplets, and visually cleaner windows for several weeks.
