After a shower, my bathroom mirror is badly fogged over, which makes shaving inconvenient, and the worst part is, it just won't go away! Wiping the glass barely does anything, and splashing water (hot or cold) on it washes the fog off for about half a second, and then it condenses and fogs up again.
Is there any good way to clear the mirror off without having to open the door and let the nice, warm, steamy air out of the room?
