i go about it this way.
tumble clean brass for about an hour once i get back from the range, deprime/resize or necksize, tumble clean again for no less than 2 1/2 hrs (really closer to 3-3 1/2 hrs) to really shine and get media in case and primer pocket. once i reprime them i may hit them with the primer pocket cleaner tool to knock out heavy carbon but usually the long stint in the media does the job for me.
