My family immigrated from the USSR and even though we've lived in places that had dishwashers, we've never used them. We just do everything by hand and it's fine??
Even if you do use it; I can understand getting all the chunks off before putting dishes in there, but if you're rinsing it off too, just rub it with a soapy sponge a bit and you're done?? Why would you almost wash it and then put it in the washer? It's like cleaning before the maid comes.
If the answer is "so they're sparkling clean every single time" then you're a bougie and need to learn to have some humility. Some water stains on the bottom of your plate are a non-issue.
Edit: after reading the comments and talking it over with my friends, I've decided to elaborate a bit
Washing dishes by using a soapy sponge and running water: the best way
Scraping them then putting em in the dishwasher: oooh look at mr fancy pants over here. But if you're running full loads on a new efficient washer then I guess I'll allow it
Rinsing plates then putting them in the washer: fuck you
Filling the fucking sink with soapy water to wash dishes: what the actual fuck is wrong with you go back to your fucking Norman Rockwell painting you absolute psychopath
I used to work as a dishwasher.
The sinks/nozzles/water temp in every place I've lived have been too small and consumer-grade sponges kinda suck. It's easier just to spray everything off and stick it in the dishwasher.
washing dishes at home vs in a commercial dish sink makes me want a commercial 3 tub sink in my house.
