Hand Sanitizer
We have no soap. Instead, we have hand sanitizer. We use it to shower, do the dishes, bathe the dog. In fact, now that I think of it, we don't even have water. One night at dinner, way back when we started making this a habit, Little Bobby took a big gulp of hand sanitizer after finishing his pork and beans and threw up.
"Mommy, Daddy . . . I threw up . . . ." Bobby coughed.
"Well, go clean up in the bathroom and use the hand sanitizer."
