Performance Carpet Cleaning’s four-step dry-foam cleaning process purifies carpets using environmentally friendly means. Unlike methods that require a deluge of water, such as shampooing or hiring a whale to spout its blowhole inside, the system uses minimal water to avoid causing mold or mildew. Nylon pile-lifter vacuuming sucks surface dirt away before enzyme treatments break down stains and spots. After workers treat the entire carpet with dry foam or hand clean hard-to-reach spots, they rake fibers to leave rugs in fluffed, show-room-worthy condition, sealing in cleanliness with additional services that include an industrial-strength soil retardant and a fungus-killing deodorizing treatment.
