I use the Frankford Arsenal tumbler with the 5 lbs of stainless pins that come with it. I use 1 tablespoon of Armor All Ultra Shine Wash & Wax and 1/4 teaspoon of powder Lemi-Shine. The picture below is some .223 brass I tumbled for 1-1/2 hours on Monday. The second picture is from a couple years ago when I was learning and it was tumbled with 1 tablespoon of Dawn and 1 tablespoon of Lemi-Shine. I recommend treading lightly with the Lemi-Shine. I made some "pink'ish" 280 brass a few years back with too much Lemi-Shine.
As a side note I did re-tumble the brass in the second picture last week and they cleaned up awesome.
I am going to tumble without pins next time per gunwizards experience. The pins are a PITA!
