Accell Clean® SWA – Surface Washing Agent

Accell Clean® SWA is a biodegradable heavy-duty cleaning agent designed for cleaning oil-contaminated surfaces, including contaminated shorelines, mangroves or sea grasses resulting from oil spills. SWA accelerates the natural bio-degradation of organic contaminates and can also eliminate odors and create a safer environment in the bilge area as volatiles are decreased and/or eliminated. SWA is recognized by the EPA as a surface washing agent.


Recommended application rate is 1 gallon per 100 square feet, dependent on the amount of oil and the degree of weathering. For weathered crude oil from sand, prepare a cleaning solution of 0.25%-2.0% Accell Clean® SWA using fresh or salt water. Spray Accell Clean® onto oil-contaminated shorelines, mangroves, or seagrasses full strength as applied. Allow to soak for 15-30 minutes. Rocks may be scrubbed with a stiff bristle brush where appropriate. Rinse with fresh or salt water as appropriate. For weathered crude oil on sand, transfer oil-contaminated sand to sand washing equipment. Agitate sand/Accell Clean® SWA solution. Accell Clean® SWA will lift the oil from the sand due to its low interfacial tension. Remove water from sand by centrifuge.

Storage and handling

Accell Clean® SWA should be handled with protective gloves and eye/face protection. Wash hands thoroughly after handling. Test compatibility of product with rubber and plastic components before full scale use. Accell Clean® SWA has a shelf life of 2 years.
