How can I keep my bathroom mirror from fogging up after a shower?
Provides methods to apply anti-fog coatings or manage humidity to prevent steam from condensing on the mirror surface.
- Improve bathroom ventilation to reduce steam4
Reduce mirror fogging at the source by moving humid air out of the bathroom before it condenses. Turn on the exhaust fan before you start showering and leave it running for 15-20 minutes afterward.

- Apply shaving cream or soap film to the mirror4
Rub a thin layer of shaving cream or bar soap onto your clean, dry mirror, then buff it clear with a soft cloth. The invisible surfactant film left behind prevents water droplets from beading up into fog.

- Use a commercial anti-fog spray4
Spray a purpose-made anti-fog product onto your clean mirror, then buff it dry. These sprays deposit a hydrophilic coating that prevents moisture from forming visible droplets, keeping the mirror clear through multiple showers.
