Green Seal™ GS-37 certified. Environmentally-responsible formula contains no butyl, phosphates or caustics so it’s safer than traditional heavy-duty cleaners for both users and surfaces. Designed for soil removal in areas where a neutral cleaner isn’t strong enough. Great for cleaning finished floors, walls, painted wood, concrete floors, plastic and any other water-safe surface. Use in auto-scrubbers, buckets or spray bottles.
