I routinely wash my crushed corncob tumbling media probably 2 to 3 times a year.
I place it into a couple of laundry bags that women use to wash their smalls in (available, if I remember correctly, $4 for three bags from Spotlight). They have a zipped closure.
I then agitate them in the laundry tub with a bit of standard laundry detergent (what ever the wife has) and it is really surprising how much ****** comes off/out. The media is a completely different colour once cleaned.
I then lay it out on a towel in the workshop to dry over a few days.
While I wet tumble brass with stainless steel pins, rather than metho or whatever at the end, I toss them into the vibratory tumbler for a couple of hours still wet. This dries them and finishes off the polishing beautifully.
