You're awesome! Thanks for your most excellent Martian and academic perspective!
If this particular Martian would retreat to his cave in the bathroom and scrub his bathtub a little more often, I might have done exactly that! He lives in a suburb with really bad (aka hard) water, and his shower/tub is a bit of a nasty mess. I tend to stick to simple showers, but that still might have worked anyway! Thanks for the suggestion; I'll put that in my back pocket for future use!
