The rotor blades (11) and hub (10) of the compressor wheel (1) are cleaned by means of a cleaning fluid stream (72) directed along the rotational axis (A) of the compressor wheel onto the compressor wheel. The cleaning fluid stream is run towards or sprayed at the compressor wheel by a supply nozzle (51) arranged on the axis and directed along the axis in the direction of the compressor wheel. The supply stream (72) thus follows the axis and hits the rotational centre of the compressor wheel on the hub of the compressor wheel. The cleaning fluid is thus introduced on the compressor wheel at the rotational centre of the compressor wheel. The cleaning fluid thus runs along the surface of the hub and is carried radially to the radially outer regions by the centrifugal forces.
