Just as grandmothers always knew to reach for club soda when eradicating a stain, Chem-Dry Clean Masters’ expert techs know that the fizzy power of tiny bubbles can revitalize carpets as well. They treat dirty rugs with The Natural, a carbonating solution that burrows deep into trapped stains before lifting offending dirt to the surface, where it can be easily removed. The cleaning system also eschews soap—leaving carpets free of residue—and uses one-fifth the water of traditional cleaning systems. Beyond simple carpet cleaning, Chem-Dry employs a special system for removing pet odor that journeys below the carpet fibers, cleaning down to the backing, padding, and subfloor if necessary. Technicians also traffic in a specialty spot remover that erases the stains left by ketchup, jelly, and leg-wrestling matches with the Kool-Aid Man.
