I find ultrasonic cleaners work... okay. At least the semi-industrial looking cleaner that I got. The first one I bought was a plastic ovoid toy, and it was useless junk. But often heavy wax buildups turn into this weird crumbly stuff that still requires mechanical action to remove.
The best solution I find is to flow lots of hot water over the surfaces, and use a medium bristly paintbrush to gently rub every nook and cranny. Then do a final cleanup using isopropyl alcohol, again with a brush.
