I'm happy to wash my hands and use those disinfecting liquids and towlettes when I can't wash - preventing diarrhea is a good thing, no matter where you are; but showering and bathing are not high on my list. As the Old Bald Guy says, spit baths work fine for my wife and me. We heat water in the coffee pot and both use the water to bathe with some soap, then rinse off with our garden sprayer. Very little waste, and we often camp dry where there is no water but what we bring, so that's important.

I've tried the no rinse shampoo, but I didn't find it really useful on a week's camping trip. Just more gunk in my hair.

Everybody's mileage varies, and the tolerance for human smell does, too. :-> If it keeps up camp morale being clean, go for it. I'd rate hand washing as a top priority, though.
