Post-rinse of the containers is carried out in order to remove the cleaning solution. The post-rinse includes an earlier rinsing phase in which a containers is rinsed with a first rinsing fluid, and a later rinsing phase rinses out one of the containers that has gone through the earlier rinsing phase with a second rinsing fluid. The second rinsing fluid that has been used in the later rinsing phase is used as the first rinsing fluid in the earlier rinsing phase of the post-rinse.
