Washing dishes with superheated steam more effective, earth-friendly

Conventional dishwashers often do not kill all the harmful

microorganisms left on plates, bowls, and cutlery. They also require long cycle times that use large quantities of electricity, and the soap pumped in and out is released into water sources, polluting the environment.

Superheated steam dishwashers could provide a more effective, environmentally friendly solution.

Researchers simulated such a dishwasher, finding that it killed 99% of bacteria on a plate in just 25 seconds.

The superheated steam dishwasher would initially cost more but would pay off in the long run with savings on water, electricity, and detergent. It would be ideal for use in restaurants, hotels, and hospitals, which must meet high hygienic standards.
