A process for the removal of organic materials from the surfaces of drive components, particularly for the removal of meltable organic coatings, fillings or damping materials. The organic material is first melted in a bath of the same or similar organic material and an adhering residual film is diluted and stripped off from the preheated drive component by applying tempered oil thereto. After this, a diluting and striping off of a material film, which essentially consists of oil molecules still adhering to the surface, is conducted by applying an organic cleaning agent, which is free of fluorochlorohydrocarbons and chlorohydrocarbons. Then a post-treatment of the surfaces of the drive component is effected by one or more steps of applying diluted cleaning solutions with intermediate rinsing and/or drying steps, in which the cleaning solutions are increasingly diluted stepwise.
