Abstract

A method for cleaning and/or disinfecting an item to be cleaned is proposed. The item to be cleaned is exposed to at least one cleaning fluid, heat equivalents to which the item to be cleaned is exposed being recorded. The heat equivalents are added up, the heat equivalents additionally being weighted with a compensation function during the summation of the heat equivalents. The compensation function can be a function of the temperature at which the heat equivalents were recorded. The compensation function can be adapted to provide heat equivalents recorded in at least one exceptional temperature range with a lower weighting than heat equivalents recorded in other temperature ranges.
