Is ultrasonic cleaner the way to go?

[BDman]

Wet tumble, SS pins with Dawn (1/4 tsp of Citric acid if you want real shine) and no more than 1:45. You'll have super clean brass with just a little Carbon color left inside the necks and minimal peening of the case mouths which is taken care of with a couple turns of a deburr tool. No downside except double checking for pins and dry time. Makes it very easy to inspect brass.

Edit: I might try adding a cap of Nu Finish car polish next time. My friend did it a couple of months ago and his brass still looks like it just came out of the tumbler. He said bullets seated more smoothly too. I always dip them in graphite - he doesn't.

SS pins, dawn, pinch of lemishine and tumble for 90 min and then an hr in an old food dehydrator to dry them. if I have just a few, I'll toss them in the ultrasonic. Got rid of the vibratory cleaner.
