I’ve done the mineral spirits thing and it gave my brass a slight “grey wash”Add a cap full of mineral spirits as well
I came here to say this. I would not tumble primed brass.I wonder if corn media or anything smaller that can pass through the flash hole effect the primer going off? I've never tumbled primed brass but I always get media stuck in the flash holes.

I would not tumble primers. No, I would not do that.I am about to take delivery on a large quantity of brass that will need a little tumbling before I sell it. I cannot wet tumble this brass as it is primed and ready to load, just a little tarnished from age and storage.
I'm thinking of trying aluminum oxide as an additive, similar to how a rock tumbler might. Would you use a different additive? 80 grit or finer? I don't want to have multiple steps in processing this brass so one tumble and bag by count for sale is my objective.
Thanks in advance.
