Combi-Clean is a true all-in-one carpet cleaner that cleans, deodorizes, defoams and protects the carpet from resoiling. Use with extraction type machines. Combi-clean revitalizes carpets and upholstery. Deep cleaning action removes heavily embedded dirt and soil for an almost new appearance. Low pH formulation is recommended for use on all carpet fibers. Rooms are left with fresh clean scent and no sticky residue. Concentrated for greater economy.
