Abstract
A cleaning unit (A) includes a movable cart ( ) which carries a cleaning system for cleaning baked-on residues from walls ( ) of a sterilizer chamber ( ). Alkaline and acid cleaning solutions ( ), for removing organic and inorganic residues, respectively, from the chamber, are stored in a multi-compartment container carried by the cart and having two storage compartments ( ). The alkaline and acid solutions are sequentially sprayed over the chamber walls and returned to their respective compartments. After cleaning is complete, a wall ( ) which separates the two compartments is punctured. The two cleaning fluids are thereby mixed together to form a neutral or near neutral solution which is disposable in a sanitary sewer system without further treatment.
