Restaurant dishwashers are a different beast to what you have in your kitchen. Gets the job done in seconds. Of course, they are also very expensive, really loud, uses very hot water, are really large, and probably use harsher chemicals.

I worked in a hotel kitchen as a teenager in the early 70s. I don't think we used any chemicals at all in the dishwasher. But we did rinse the dishes first. They were so hot when they came out of the washer that they dried instantly and were too hot to handle with bare hands.

This is not far off how your dishwasher at home works either - open it when it switches to "dry" mode and you'll notice that everything is hot as hell. The "dry" time is relaly "cooling down" time.

Oooh, yes. Though the "done in seconds" commercial dishwashers are a good number of model & feature upsells above the most basic ones. Might need 240V and serious amps, too.
