hey there, i'm not new to handloading but new to mechanical case cleaning. my wife bought me a rcbs vibratory case cleaner for fathers day(ain't she cool?) and of course a simple thing as cleaning media has to have many choices. walnut, corn cob, brass polishes. i'm not really wanting a 3step process to clean and shine my cases so, what do you guys use as media for everyday case cleaning in your vibrator? thanks for the help
