ABSTRACT:
The invention relates to a method for cleaning a washing device (5) of an offset printing machine, according to which at least one washing device of said offset machine, which comprises a spray bar (11), is removed prior to the cleaning process and placed in a cleaning bath (17). The aim of the invention is to achieve improved cleaning results in a shorter time, in particular using fewer personnel. To achieve this, ultrasonic waves are directed onto the washing device in the cleaning bath that is filled with a liquid medium and during the cleaning of the washing device using said ultrasonic waves, the liquid medium is conducted through each spray bar. The invention also relates to a cleaning device (16) for carrying out said method.
