A dishware cleaning method for use with a dishwasher, comprising the following cyclical steps: pouring a washing liquid into a washing container; generating air to the washing liquid to form small air bubbles; the dish rack linearly reciprocating or rotating to form an irregular vortex to drive the small air bubbles to be evenly distributed in the washing liquid; discharging the washing liquid; and repeating cyclical washing procedure until the dishware is washed clean to complete the washing procedure. By means of introducing air into the washing liquid to form small air bubbles and by causing the washing liquid to flow by means of the movement of the dish rack, the scrubbing strength of the washing liquid on the dishware is increased and the adhesive strength of grease on the dishware is reduced, thus achieving a good washing effect.

The present disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pro-determined volume or timed flow of water, and exposure time of sanitizer(s) to the intended objects. The spray embodiment has high performance conical spray nozzle(s) controlled by a controller that reduces water usage and that may vary depending on the viscosity of the material to be eliminated. The recirculating embodiment has a recirculating water system, with a controller operating the components that recirculate water throughout the system until the turbidity exceeds a chosen threshold, and displace with fresh water until the turbidity returns to a lower threshold. The water resumes recirculation until it again exceeds the chose turbidity threshold and the water in the system is again displaced by fresh water. Both spray and recirculating embodiments can contain multiple rinse stations.
