I don't have Dr. Bronners, but I do have Camp Suds. Can I use it as an alternative? Also, I tend to wear fewer but better quality wool than cotton wear. So I think I would rather just hand wash my clothes. How often is reasonable to wash wool? I think once every two weeks or 8 to 10 uses seems good. My GF gets grossed out by the idea of washing clothes so infrequently, but wool really doesn't retain smell.
