Many dishwashers will clean all of that fine, in my experience. The annoying part is the cups or bowls that may fill with water, just make sure they’re upside down.
As far as scraping or rinsing things…. Nah. Haven’t done it since I worked in food service and saw what dishwashers could do. Some stuff needs scraped, sure, but most will come off under the detergent and hot water.
Okay well I worked fast food and now I’m a software engineer so I don’t see myself being fired by a chef any time soon
I chuck food into my own home dishwasher all the time and no problem, so maybe you just aren’t doing it right lol
