I have wet tumbled for the past 5 years. Old lortone 12lb rock tumbler bought used off ebay. Original 5 lb SS pins. 1 teaspoon lemishine, few drop of dawn and tumble or about 90min to 2hrs. rinse till clear in sink. Separate in Dillon separater. Do this on a black sheet to easily locate runaway pins. spread out in sun for a couple of hours or put in a wire basket and dry in oven for an hour at 200 degrees. Shiny, clean brass and other than lemishine haven't had to buy anything else in 5 years. Completely satisfied with results
