I was a nurse before I was a teacher and taught healthcare science for 2 years. Believe it or not I taught future nurses how to wash their hands. When you break it down, you actually trap the bacteria or germs in the bubbles and foam when you rub your hands together with the soap. Then the water washes them away. It really isn't the soap itself that kills the germs. That is why it is more important how long you wash them and that you get all areas, and not what kind of soap you use. I hate that germ-x stuff. The germs are still there. It's just some are dead, and the strong ones live. Hence, the resistant bacteria. Your hands aren't clean, you just have dead germs on them. Kinda sounds gross doesn't it.
