Cleaning shotgun hulls

[thegunnut]

So… having discovered a large qty of sub gauge hulls in my basement, I am looking for advice on how to clean shotshell hulls prior to loading.
They are sooty, gritty, and dirty, with sawdust and drywall dust throughout.
Nothing I would like to put through a sizing die on my press.
Short of hand wiping / cleaning each one…. And knowing my wife will damage me severely if I put them through the washing machine or dishwasher….
Anyone have any techniques to share for cleaning them up?

I deprime them and put them through my metallic tumblers . Doesn't take long to clean them up. Water is a no no for me .

You can't wash any hulls with paper base wad.
You would certainly need to ensure that moisture didn't remain between the metal base and plastic tube of all plastic hulls.
I clean range pick-up hulls with a cloth outside, and a bore brush inside. We have a fine sand range soil.

Air gun and a tank of compressed air?
