  • the rinsing step then has essentially only the function of displacing contaminated circulating water with dissolved impurities, which wets the surfaces of the ware, with clean final rinse liquid, so that dissolved or suspended dirt residues can not re-adhere or dry on the surfaces.
  • the method may additionally comprise a disinfection step in which the at least one excretion vessel is disinfected.
  • a chemical disinfection step is also possible, for example, to use a thermal disinfection step, for example a steam sterilization step, but this is not preferred for reasons of economy of business and is not required due to the more thorough mechanical cleaning of the items to be washed.
  • the at least one excretion vessel can be wetted with a disinfectant, preferably a disinfectant solution.
