Abstract

The present invention relates to a method for cleaning objects, characterized by degreasing the objects with an aqueous tenside solution, such as to emulsify the hydro­ carbons present, and by stimulating the growth of micro­ organisms for biodegradation of the hydrocarbons, by adding nutrient substances to the system. The invention also claims an apparatus for performing the method.
