Bleach is used to kill bacteria in much the same way as this clay, has been for a long while.  Bleach is used worldwide to purify drinking water.  It is used, in diluted form, on skin infections.  In a way, I personally use it to prevent athlete&#x27;s foot.<p>If you swim in a chlorine pool (diluted bleach) as much as I do, nothing lives on your skin for long.  Swimmers don&#x27;t suffer athlete&#x27;s foot.
