Though a mustache doesn't seem the most hygenic tool for washing your hands, trust me on this one.
Does your heart die a little when you have to throw away that last little sliver of soap? Now you can save it! You have now personally solved all our ecological problems!
Repeat after me: I will not eat the soaps, I will not eat the soaps, I will not eat the soaps!

Guest soaps don't always have to be cherubs and seashells you know.
