For a Cleaner, Healthier Home. The Earth uses water to cleanse itself of surface dirt, airborne particulates, allergen, dust and man‐made contaminants. It washes the air and cleanses the environment in which we live and breathe. It’s only natural. This works great for outside, but what about inside your home? The Rainbow Cleaning System cleans your home the most natural way possible, using The Power of Water®. It not only cleans your home… it creates a healthier living space.
