I ultrasonic clean my cases in citric acid (lemon juice) solution.
20 times faster than a tumbler (about 5 minutes for a batch of 20 cases) and no need to pick the walnut shells from the primer holes.
Result, shiny clean cases and my tumbler is now redundant.
Rinse in clean water and put them on a tray into the oven set on dead low for 15 minutes
