Janice and Tom Stewart, founders and owners of Modern Cleaning, have released their first book on the science of cleaning. Modern Cleaning: The Evolution of Chemical Free Cleaning traces the history of cleaning as a science, through the disciplines of biology, chemistry, and physics.

“The future of cleaning is science,” said co-author Janice Stewart. “Amazing discoveries about the properties of water, energy and matter are transforming the very concept of clean. This book is about that transformation and what it means for consumers and the cleaning industry.”
