Does anyone know of a truly odorless soap in bar form? I have a hand-washing system in camp where I put a small bar of soap in a nylon stocking and hang it in a tree or bush next to a small reservoir of water. Ideally I'd like to have the soap completely odorless so as not to attract bears or other critters. I know that there are soaps that supposedly remove human scent (e.g., "Dead Down Wind"), but I think the soaps themselves are scented.
