I separate all my brass by caliber then de-cap and resize my brass first.
Then ultrasonically clean in a mixture or 50% Water, 50% White Vinegar. And sever drops of Dawn Dish Detergent.
I dry the brass in my dryer in a leg from a pair of jeans tied at both ends. I toss in 3 or 4 old towels to reduce the noise.
.
Then I put the brass in a vibratory tumbler.
My tumbling mix is as follows:
60% White Rice, 40% Lyman Red Rouge Coated Corn Cob Media (let that tumble around for 1/2 hour and the rouge disperses to all the rice).
I mist a bit of Kroil on the media and let it mix up real good (just a couple of mists over the top surface and let it roll for a bit, 2 or 3 times)
(OK, why white rice you say? It's pointy at the ends and gets pointier as you use it. It cleans into corners exceedingly well)
.
Put brass in tumbler after wards and let it go overnight.
The brass comes out like you polished it on a cloth wheel, inside and outside, primer pockets too.
