I don't use anything but hot water and "vigorous agitation", no. Though as noted I do end up using shampoo (diluted Dr Bronners) on occasion. For the rest i use a coarse washcloth, and I think I come out cleaner than those slathering themselves with "product". I'm currently talking myself out of using soap on the pits, though I think it will take much more time (and probably some other lifestyle changes) to stop using it on the nethers.
