It seems a strange and wrong assumption of the general public that living in the wilds means being perpetually dirty. Yet, I get students all the time that assume that they’ll not be washing at all for their stay here, and they seem shocked and slightly let down when I hand them a chunk of Yucca root and tell them to take themselves to the river and wash LOL.
Being in the SW, we use dried Yucca root for soap/shampoo. Works great, even gets nice and foamy, works even better if you can powder it, but good luck without an industrial grinder. We also use a scrub made with sea salt and honey and various local herbs for washing too. It smells nice as well.
What do other people do to stay unsmelly and clean without civ products?
