    Abstract: The process of continuous machine dishwashing, which can be carried out in single-tank or multi-tank machines, is improved by the machine-operated process disclosed. This is achieved, in particular, by treatment of the tableware at least in one process step with an acidic cleaning solution and in another process step with an alkaline cleaning solution, comprising the steps of: a) applying an acidic aqueous cleaning solution to the at least partly soiled tableware and b) removing the acidic aqueous solution and the soil in one or more following steps, the at least one alkaline treatment taking place before and/or after the acidic treatment and the alkaline and at least acidic aqueous cleaning solution at least partially neutralizing one another.
