I got a big ultrasonic cleaner, I think 6 liter, that works great with boiling water, a squirt of dish soap and a teaspoon of citric acid powder. Seperate out any steel cases or your brass turns pink.

If you're in a hurry dry with a dehydrator or rack over wood stove.

You do have to lube case necks, 375 Ruger likes to turn inside out when seating bullets if not.

I use the same rig and solution to degrease parts like carb heat boxes or heater valves for airplanes before sand blasting.

There is no retreat but in submission and slavery!
