Glycerin is a specialty product you can get from the pharmacy that can also be used diluted with water to wipe down mirrors and keep them fog-free during showers. Fogless mirrors with chemical-based coating are one of the most popular options. Keeping them exposed when not in use strips off their coating.
Have you ever heard of heated mirrors? Yes, they exist. They have reservoirs placed behind the mirror, which mimics the temperature of the water. Mirrors attached to the shower pipe also work effectively. This basically requires a valve which extracts water used for heating the mirror.

Clearly, for fogging to occur, the steam, originating at the shower spray, must reach the mirror. Also it should be quite clear that steam a gas has to "travel" through the air to reach the mirror location. When you turn the cold water on first, and leave it for some time, you cool the air in the bathroom, some.
The process of steam generation, its transport away from the water spray, and possible recondensation in tiny aerosol droplets while it is being transported by, and through, the surrounding air is very complex, but crudely put, steam cannot go too far when the surrounding air is relatively cool.
Thus, no fogging if we pre-cool the air by turning the cold water on first. However, even in cool air, the water will vaporize and will tend to heat up the surrounding air as it condenses in it. Since the air is easy to heat, we would expect that the effect of pre-cooling is short lived, and only a matter of time before the mirror fogs over.
So, we can now see that the statement "the mirror wouldn't fog" is incorrect. By Kathy Adams. Related Articles. How to Prevent Steam on the Bathroom Mirror.
