Abstract

A method and apparatus for cleaning a printing cylinder surface in a printing machine of strongly adhering dirt, such as paper dust and hardened printing ink. This is achieved by applying a predetermined coating of alkaline cleaning agent to the printing cylinder surface by a cleaning roller and allowing the cleaning agent to act on the surface for a defined time, preferably greater than sixty minutes, and then subsequently removing the cleaning agent from the printing cylinder surface by means of a cleaning fluid, such as water.
