On a whim I bought a Harbor Freight ultrasonic cleaner, and cleaned a few handsful of 308 once fired .mil brass. Not knowing what to expect, I ran them through 3x 450 seconds, and turned the heater on.
The water gets cloudy, but I can't say it ever really gets dirty. The insides of these cases were black and universally disreputable looking. Using a 50/50 vinegar/ tap water solution with a couple drops of Dawn Dish soap, they came out remarkably clean as did the primer pockets.
For blasting type ammo that doesn't really matter that much I will probably still tumble it. But for ammo that matters, I will use this cleaner.
I would recommend folks give it a try.
The next batch I run through I will just try the few drops of Dawn and see if I get good results as good as that with the vinegar/water solution. The cases have a little bit of a pink hue on them, as I started the "neutralizing" solution of baking soda and water. I suspect the vinegar may have had something to do with the pink hue... it isn't like "hot pink" or something, but the cases sort of look like how new Remington brass does in the bag, just a little pink in places.
