Abstract
A method of cleaning contaminated industrial equipment. An aqueous solution containing an enzyme and a surfactant having the formula: ##STR1## where n is 6-20, is agitated in contact with the equipment to remove oil contamination and provide a water/oil dispersion. The water/oil dispersion is then permitted to stand in a quiescent state to form an oil phase separate from the water phase, and the oil phase is then separated from the water phase.
