요약 없음 In the cleaning and disinfecting of heat- and corrosion-sensitive medical devices, especially endoscopes, a) those surfaces of the endoscope which are to be treated are brought into contact with a cleaning and disinfecting solution which contains a low-foam, non-ionogenic surfactant, a proteolytic enzyme, a complexing agent, an aldehyde from the group consisting of formaldehyde and aliphatic dialdehydes with 2 to 8 carbon atoms, and if appropriate further conventional cleaning and disinfecting constituents, and which has a pH value of 6 to 8, the cleaning solution is heated to 55 to 65 DEG C, kept at this temperature for 1 to 15 minutes and is then separated off, b) the surfaces to be treated are flushed at least twice with water, the water being heated to 55 to 65 DEG C at least in the final flushing, and c) drying is carried out with sterilised hot air at 40 to 60 DEG C. In steps a) and b) water with a hardness of 3 to 8 DEG d is used.
