Dry Carpet Cleaner is all natural and contains a balanced blend of
moisture, detergent, and a small amount of safe-to-use solvents. HOST
dissolves and traps greasy, oily dirt, spots, and odors as it's
brushed into the carpet. To remove, wait for 2-3 hours and simply
vacuum. And because HOST is a low-moisture cleaner, carpet can be
walked on during cleaning and is ready for use immediately after
cleaning. The product is safe for people and pets."
