Die Erfindung betrifft ein Verfahren zur Reinigung eines von Wänden (11') umgebenen Nutzraumes (10) eines Brutschrankes (1), bei dem durch Erhitzen eines Wasserreservoirs (2) Wasserdampf erzeugt und gleichzeitig Wasserdampf an den Wänden (11') des Nutzraumes und an gegebenenfalls im Nutzraum (10) vorhandenen Einbauten (15) auskondensiert wird.The method involves generating steam in a usable space (10) of a climatic cabinet (1) by heating a water reservoir (2), and simultaneously condensing the steam on walls (11') of the usable space, where the usable space is surrounded by walls that are adapted to be heated by a heating device (3'). The heating device is switched-off during a cleaning procedure. The walls are cooled during the cleaning procedure by a cooling unit (4), where the water reservoir is arranged in a floor area (12) within the usable space or outside the climatic cabinet.
