Ecoone PIPE cleanser utilizes a proprietary blend of alkaline cleansing agents combined with non-foaming surfactants to penetrate deep inside your whirlpool or spa's plumbing and equipment to scrub away biofilm and organic, mineral and chemical contaminants. Ecoone PIPE cleanser even helps to 'restart' rotating jets by eliminating contaminants that clog them. Ecoone PIPE cleanser will not cause excessive foaming.
