A cleaning machine for containers, especially bottles, which includes an endless transporting system for transporting containers to be cleaned through the machine, and which also includes a water pre-softening arrangement comprising at least two softening baths arranged one behind the other when viewed in the container transporting direction of the transporting system with the respective front bath having a lower temperature than the respective succeeding bath. The transporting system is over a considerable portion of its transporting path passed through the softening baths in submerged condition so as to also submerge therein the containers being transported by the transporting system.

The method of washing containers which are open at one end in a bottle cleaning machine, and in which said containers are transported successively from a charging station where they enter the machine through heated liquid baths and are sprayed with heated liquid, the steps in combination therewith comprising: first transporting said containers successively from said charging station through a first liquid bath in a leading vat with the containers submerged in upright position to fill with liquid in said first liquid bath, inverting said containers leaving said bath to empty said containers of liquid, then transporting said containers through a second bath in a trailing vat with the containers in inverted position so liquid does not enter to fill the containers, transporting said containers through the machine to a spray station to spray said containers with heated liquid, conducting the heated liquid from said spray station back to said second bath in said trailing vat to heat said containers in said second bath in said trailing vat, conducting liquid from said second bath in said trailing vat to said first liquid bath in said leading vat to warm said containers just entering said machine to a lower temperature than in said second bath in said trailing vat, and discharging said liquid at a low temperature better for environmental purposes after warming said containers in an energy Saving manner when entering at said charging station free of need for costly external heat supply thereto from the outside of the machine.
