Most of the time I just tumble my brass with Lyman tumbler but when I'm feeling especially anal or have some really dirty brass I will deprime, run it through the ultrasonic cleaner for a few cycles and then drain it and shake it out a bit and then tumble for a couple of hours. Comes out bright and shiny with clean primer pockets. My biggest pet peeve is the media that gets stuck in the primer pockets.
