How do they sanitize mud for spa use?

Question

I'm curious how mud gets sanitized for spa use (mud facials and mud baths). Do they use chemicals or what?

Answer 1

Hi:  Do you mean reuse of the mud?  As a spa consultant, I can tell you spas should pitch the mud after every treatment.  Reuse is definitely not an option.    If you mean sanitized before initial treatment use, the mud for the treatments is usually heated and mixed with other ingredients just like any skincare products.  There are labs all over the world that use mud in their products, usually heating it to combine it with moisturizers, etc.  Hope that helps, Candace

Good question but one I never considered. The mud you buy in a health store for home use is a powder. So, I'd suppose the drying process, which probably involves heat, would sterilize the clay, much like soil is sterilized to use for seed starting. To use, you mix water into the powder and it becomes clay again.
