Kat, I think it's a good idea to use hand sanitizers, too - when soap and water is not available. I still haven't any indication at all that these "sanitizers" are better than soap and water. Logic tells me that it is better to wash contaminants away, down the drain; rather than just putting a chemical on that might kill some of the contaminants. And yes, I am well aware that many organisms stay on hands even after a long scrub.
