A low-pressure system for cleaning items includes a tub, at least one steam head mounted in the tub having a rotatable nozzle configured to direct steam towards the bottom of the tub. The steam generator is in fluid communication with both the first steam head and the second steam head. A valve including a foot pedal mounts in fluid communication between the steam generator and each steam head. The steam generator connects to a water and power source for generating dry steam at a temperature exceeding 300° F. and at a pressure of less than 150 psi. The dry steam maintains a dryness fraction of 0.4-0.9 at all points within the system.
