Method and device for cleaning and/or disinfecting a device for producing containers filled with a liquid filling material

A method for cleaning and/or disinfecting at least an openable and closeable multipart mold of a molding and filling station of a device for producing a container filled with a liquid filling material from a thermally conditioned preform made of a thermoplastic material by stretching the thermally conditioned preform in an axial direction using a plunger and simultaneously molding and filling the thermally conditioned preform in the multipart mold with the liquid filling material supplied under pressure, the method comprising:

• carrying out a cleaning and/or disinfection operation of the device by applying at least one cleaning and/or disinfecting agent to the multipart mold when the multipart mold is opened and when the multipart mold is closed such that the cleaning and/or disinfecting agent is applied to external surfaces of the multipart mold and to inner surfaces of the multipart mold and to opening edges of the multipart mold and such that liquid filling material residues are removed from the external surfaces of the multipart mold and the inner surfaces of the multipart mold and the opening edges of the multipart mold by the cleaning and/or disinfecting agent applied thereto;
• and
• optionally, applying the cleaning agent and/or disinfecting agent while the plunger is moved at least once between an initial position and an end position such that the liquid filling material residues are removed from the plunger by the cleaning and/or disinfecting agent applied thereto.
