FIELD: cleaning methods. SUBSTANCE: invention relates to methods of cleaning objects from hydrocarbon compounds, particularly, from oil products, oils and fats. According to proposed method of surface cleaning from hydrocarbon compounds in closed cycle using water solution of technical detergent forming unstable emulsion with hydrocarbon compounds, solution is fed to surface to be cleaned and then emulsion formed on surface is removed and directed into reservoir containing water solution on technical detergent for partial separation of solution and coarse separation of hard particles. Emulsion from reservoir is fed for separation into hydrocarbon compounds and water solution of technical detergent which is then returned into said reservoir, and hydrocarbon compounds with remnants of solution are fed for fine separation of hydro carbon compounds and wear solution of technical detergent. Said solution if any, is also returned into reservoir. EFFECT: improved efficiency, cut down time taken for cleaning. 3 cl, 1 dwg
