So again I will say something that will set get a furor going, or at least a grumble. Dirty cases do not harm a thing, no accuracy, not precision, nor your dies, just your sense of prestige. Everyone (including moi) likes to show off their classy finished end product, which object is your a shooter/reloader is the target you made, not shiny brass.
Having said that, I vib my brass for about 30 mins and get one with the program.
