I'm not sure if this has been asked before.......Why would you wash your M&P soap in salt water and let dry? Martha Stewart had a show on, and during this show she made a M&P soap, washed it in salt water, let dry, rinsed and it was ready to go. She wrapped it in unbleached parchment but did not wrap it in anything else. Will the salt water bath keep it from sweating? Suzie
