A biodegradable degreaser and cleaner is a chemical used to remove oil, grease, dirt, sludge, and grime from machinery, engines, floors, tanks, and metal surfaces. Unitor Enviroclean is one example of a marine-grade, water-based degreaser designed for heavy-duty cleaning. It contains surfactants that loosen grease and dirt, allowing them to be washed away with water. Its formulation is designed to be biodegradable, although the environmental impact depends on the complete formulation and how the waste is handled. The product is supplied in 25-litre containers and is used in marine and industrial cleaning.
