Dishwasher with low temperature rinse

It is proposed a method for cleaning of cleaning stock (320), in particular dishes. The cleaning stock (320) is then subjected to at least a washing process, in which adhering dirt at least largely removed. The cleaning stock (320) is then subjected to a final-washing process which has at least two sub-steps. In a first partial step, the cleaning stock (320) is applied with a first rinse liquid (338) containing a disinfectant. In a subsequent second step, the part to be cleaned (320) having a second Klarspulfussigkeit (340) is acted upon, the second rinse liquid (340) comprises at least a signal generated by means of a reverse osmosis permeate (376).
