Shower mirrors fog because the mirror surface is colder than the surrounding air, causing moisture to condense on the surface as tiny droplets. Some fogless shower mirrors function by preheating the mirror to repel condensation, while others use anti-fog agents. Some of Mirrorvana's shower mirrors use both principles.
Here are some reasons a fogless shower mirror becomes fogged up:
- For mirrors with anti-fog coatings, the anti-fog property may be depleted. You just have to reapply the coatings to restore it. Check out Mirrorvana's anti-fog sprays that come in 1-pack and 2-pack.
- For mirrors that use the warming method, the mirror may not be hot enough. Make sure to keep the mirror warm or warmer than the surrounding air by adding very warm or hot water to the water basin.
