Want clearer skin, balanced and calmer body, and fewer products cluttering your bathroom? Grab a bowl and get dirty—in the best way. Dirty Washing is your practical, science-savvy guide to using therapeutic clays (especially mineral-rich montmorillonite) for simple, effective self-care at home or in the spa.

​

Written by Denise R. Fuller, a licensed esthetician, international trainer, and the founding director of the National Aesthetic Spa Network—this book distills three decades of hands-on experience into safe, step-by-step recipes and protocols you can trust. Denise first fell in love with clay while training in Australia; since then, she’s tested, tweaked, and perfected methods that actually work in the treatment room and the real world.

 

What you’ll learn

• The Clay Basics: types of therapeutic clays, what each does best, and how to source quality product without getting duped.

• Mixing & Methods: fool-proof ratios, how to activate clay for masks, wraps, compresses, spot treatments, and bath soaks.

• Face & Body Protocols: calming, clarifying, and firming routines for different skin types—plus body recipes for sore muscles and tired feet.

• Scalp & Décolleté Care: overlooked areas that age fast (and how to love them back).

• Clean Pairings: simple add-ins (hydrosols, oils, and kitchen staples) that amplify results—no fifty-step chemistry set required.

• Safety First: who should patch test, when to modify or skip, and how often to use clay without overdoing it.

Why it works

Clay isn’t a trend; it’s geology doing skincare.

The naturally occurring minerals in montmorillonite help absorb impurities while supporting the skin’s barrier, so you get visible results without harshness or hype.

Who it’s for:

• Estheticians & spa pros who want reliable, client-pleasing protocols.

• Wellness DIYers who prefer ingredients they can pronounce.

• Sensitive-skin skeptics who’ve tried everything and are ready for something grounded (literally).
