Doubt liquid dishwasher detergent is the problem. He’s probably not pre-rinsing before loading them in.
Had a dumbass roommate that had steak and fries every dinner, and would leave the grease and a massive pool of ketchup on the plate every time, then run the dishwasher days later after everything was dry. All it did was bake it onto the plates and require some heavy scrubbing to get off.
I mean, don’t leave half your meal lying around on the plate, for sure. Dispose of your food in the manner most appropriate if you’re not going to eat it, and then allow the dishwasher to deal with whatever is stuck to the plate.
I have never found a dishwasher that requires less pre-wash than me just washing the whole dish by hand anyway. Like, if I already have to take it to the sink and start getting food off, I might as well just finish the job right there.
It’s a lot more convenient to me to just hit dishes with a nylon brush than to fully wash by hand. I see the dishwasher more as a sterilizer than a cleaner.
You’re not supposed to pre-rinse dishes. It messes up the sensors by suggesting the dishes are already clean, and detergents are designed to bind to the particles on your dishes, making them work less well.

Properly used dishwashers do not require pre-rinsing. It’s a waste to do so.
Some people take that to mean that you don’t have to clear the food residue off the plate I have found.
