Me too except with jewelry cleaner and I hold the case above the liquid. I have found I don't get much dirt out if I do it much more than once every couple of months. In the interim and about once per week I use hand soap and my hands. Finish with a thorough rinse and dry with a soft cotton or mircofiber towel.
It's far from "rocket science" and the ultrasonic cleaner is nice not required. As least this thread added something new to this well-worn topic -- the Mohs scale.
