A foggy mirror is the price you pay for those nice, hot, steamy showers. Do you towel off a streaky hole just big enough to see your face? Banish the fog with a hairdryer? How about preventing the mirror from fogging up in the first place?
The folks at The Creek Line house have a great tip for preventing foggy mirrors, and all you need is a bar of soap. Just rub the dry bar of soap lightly over the surface of the mirror, then use a clean, preferably lint-free cloth to buff the mirror until you don't see soap marks anymore. The light layer of soap on the mirror should prevent fog from condensing. In fact, it will probably last through a few mirror cleanings, even if you use a glass cleaner.
