Wool Clean was formulated from the beginning for the specific purpose of effectively cleaning the most challenging rugs and fabrics, and meets and exceeds the safe standards for cleaning wool fibers and fabrics. Wool Clean is also formulated to match the versatility of the cleaning professional, working effectively at both “on-location” and “in-plant” cleaning set-ups. It can be applied like a typical prespray or used effectively in a rug washing pit. Wool Clean is super-concentrated, most often mixed 1:16-24. It has a slightly alkaline formula with a pH of 8.0 -8.5.
