Harbor Freight tumbler, stainless pins, dishsoap and lemishine for me. I use less dishsoap and lemishine that is used in the various videos I have watched. The "secret" that is most effective for me is to bring the canister into the kitchen and use HOT water from our built in hot water dispenser. I would guess about 180-90 degrees F. 25 minutes gets the brass more than acceptably clean, 90 minutes gets the brass super shiny. The amount of brass I am trying to get through in the day determines where in that time range I settle upon.
