Here's some comparison pics. Ultrasonic cleaned brass on the right, and wet tumbled (2 hours) with stainless media, dawn, and lemishine on the left. They are right next to each other in the same light in this pic. The ultrasonic cleaned brass is just still that dirty inside.
Here's some drying on a microfibre towel after a stainless media bath. The primer pockets are completely clean on about half, and the other half still has a little carbon left in there. I could probably let them run longer or figure out a way to agitate them more while rotating, but i am more than happy with the results. I did not like the idea of carbon/lead dust flying around my workspace which is mainly why I chose the wet method.
