Every now and again I'll try something I've never heard anyone else try.
I have shot black powder for years and like a lot of folks I have gone to the wet method of cleaning brass.
I found myself with 250-300 38 special cases that had gotten over looked and were green and nasty.
I just didn't have the umphf to mix a batch of cleaner, start the tumbler, stop it and re-tighten because of the leaks then rinse them dry the etc.
I had my vibrator cleaner with worn out walnut in it setting unused. I dumped the nasty cases in it and then knowing that the walnut is not aggressive enough to completely clean the cases, I dumped a couple of cups of DDs ceramic on top of the walnut. Started it and walked away.
I came back a couple of three hours later and opened the vibrator to see how it was doing. To my surprise all cases were shiny inside and out. They did not have to be rinsed or dried and were ready to be reloaded.
Works for me but as always, your mileage may vary,
