Boiling water, one drip of Dawn, 13-16 particles of Lemi-Shine per tub in my $60 Harbor Freight rock polisher (dual container) for an hour AFTER deprimed with NO pins to mess with then on a junk cookie sheet and into a garage sale toaster oven.

Keeping this thread going but adding another comment and question. I went to load some 9mm brass that had been wet tumbled and I noticed I have a lot more effort on the loader on the up stroke after the belling operation, i.e. the expander sticks in the very clean brass case after the expander operation. I examined the expander and its fine. I also tried some brass that was only dry tumbled and did not have the issue. I ran a handful of the wet tumbled brass through the try tumbler with some polish and it expands much easier and the expander does not get stuck. This would not be a big deal except I de-primed before wet tumbling and have to check every case for dry media when I add the extra step.

Is anyone else noticing this? I ran another 500 rounds after wet tumbling only and another 500 with the added dry tumbling afterwards and the difference is like night and day as to the effort required to remove the expander from the case. I am loading on a Dillon 650.

Brass shine can be sensitive to lots of trace impurities that can sneak in or even be in your tap water.

I've given up chasing shiny, because wet tumbling produces clean brass that performs very well even without the shine.

Beauty is as beauty does, and clean brass does very well even if it's not shiny.

Dry tumbling dust is slick.
