Came up on another thread, has anyone else used this

As an oxidant, potassium permanganate can act as a disinfectant. For example, dilute solutions are used as a treatment for canker sores (ulcers) (0.25%), disinfectant for the hands (about 1%) and treatment for mild pompholyx dermatitis or fungal infections of the hands or feet. It may also be directly applied (in minute amounts) in pure form to a small inflamed and infected cut or extreme acne, "burning" it off. :-/ :-/ :-/ :-/ :-/
