So let's say you run out of soap or didn't carry soap to save weight. How do you disinfect your hands now? I ask because I was watching a channel the other day where the guy suggested using wash cloths to wipe your butt instead of toilet paper since they last longer. But one thing interesting to note is that he had no soap, and even if he did, it would not last as long as his wash rags. Nothing like eating some squirrel with your hands after rinsing the poop out of the wash rags with your bare hands. Apparently rinsing with just plain water will get rid of MOST bacteria, but not all. So what is the sage thing to do for improvised soap? Ash and fat? Does that disinfect though?
