I don't allow any of my brass to hit the ground so it's clean when I resize and decap. Some times I am given some nasty stuff from range pick ups. Depending on the amount and filthy they go in a bath of Bichwood Casey case cleaner to soak the after a day or so they get taken out and rinced. They then go in one of those mesh onion bags to hang in my wood furnace room in the winter or a sunny spot in the summer to dry. I only tumble after decapping, I have had pins break from small chunks of media lodged in the flash hole.
None get a bath if they don't pass the paper clip test either.
