A lot of information has been written about the need to have water for survival. And luckily, most people have gotten the message and either store extra water in barrels, have cases or jugs of bottled water, or have a source of fresh water than can be purified with chemicals or bleach.

Not mentioned, though, is the need to have water to use for washing your hands. Soap and water is the tried and true way to get rid of the germs lurking in our environment. But what if water is scarce with not a drop to spare? The good news is that there is an arsenal of other products that can be used to exterminate those nasty microbes.
