A high performance emulsifying degreasant for floors and machinery that replaces the traditional solvent based products. Watco Concroff contains no solvents or other chemicals that are dangerous for the environment. Watco Concroff is not, however, biodegradable and where this is important Watco Bio D should be used.

Floors - The floor must be dry before application. Brush in undiluted Watco Concroff with a stiff broom, allowing at least 15 minutes for penetration. A little water may be added to the floor at this stage to aid spreading. Too much will reduce the effectiveness of Watco Concroff. Then loosen deposits with a stiff broom or mechanical scrubber. Rinse with clean cold water preferably whilst continuing to scrub. If further applications are required, the floor should be reasonably dry before application.

Machinery, vehicle engines and chassis - Liberally coat oily and greasy parts using a soft brush or spray and brush in well. Leave for 5-15 minutes according to hardness of oil or grease. Rinse well with clean cold water. Protect any material that might be attacked or must not become wet.
