I am new at wet tumbling. I am using Harbor Freight dual tumbler, no pins. I tumble for 3 hrs, simply because the way my time is divided. My brass, either rifle or pistol are the cleanest ever. bright and shiny on the outside and roughly 80% on the inside, even the heavily tarnished that dry tumbling never cleaned. I even pulled brass out of the recycle that I gave up on is looking bright and clean. Does the Auto soap and wax help keep them from tarnishing? Do they clean up quicker? All I use is a couple drops of Dawn Dishsoap and about a teaspoon of Lemishine. I rinse until clean use Dillon Brass/Corncob seperator, put in a brownie pan and put in oven I use for baking powder coat for 10 to 15 minutes at 210 degrees and they look new.
