For the biggest part of my reloading career, I rarely ever cleaned my brass. I'd usually keep a bottle of rubbing alcohol around, and use that to put on a rag and wipe the lube off the brass after resizing it. Now days, I do things a little differently, partly because arthritis in the hands makes you change.
I use Hornady One Shot for lube, and after resizing, and I always full length resize, I put the cases in the tumbler and run them for about an hour. That cleans the lube off and shines them back up a little. Then I trim if needed, but always clean the primer pocket using the Frankford Case Prep Center.
I know a case doesn't have to be bright and shiny to use, but as I have plenty of time, I don't mind taking the extra step and cleaning them.
