Remember that nature is constantly moving. Dirt, debris, and bacteria move into an exposed area faster than it can be sterilized. For this to work, you have lay something out for a long time and have it not be disturbed, which simply doesn't happen in nature. Also remember that your skin is constantly touching things and excreting moisture and oils.
