    I use non-stainless steel shot as the final step in polishing with a
    vibratory tumbler. When it's finished, I run water through the barrel
    and out the drain hose to rinse off the shot and castings, and shake
    the barrel to knock as much loose water out as possible. Then I
    screen the shot and castings through a plastic colander whose holes
    have been altered to let the shot fit. I screen it onto a large beach
    towel that's been folded to fit on top of my washing machine
    (conveniently located next to the sink). I set the colander with the
    castings aside, and spread the shot out on the towel in a single
    layer, and then I blot it with another towel. I let it sit long
    enough to rinse the castings again and remove them from the colander
    to dry them. As soon as I'm done with that, I go back and gather up
    all the corners of the wet beach towel full of shot, pick it up and
    carefully pour it onto another dry beach towel. I spread it out
    again, blot it with paper toweling, and let it sit. Within half an
    hour it's dry, rust-free, and ready to put back in its plastic jar
    until the next use. 

    The one time I forgot to move the shot off the first towel onto a
    dry one, I got major rust. I put the shot back in the tumbler, filled
    it with water and tumbling lubricant (LR-33), and ran it for a couple
    hours with water flowing through. The rust all came off the shot and
    rinsed out into the catch pail. I have been very careful to dry it
    thoroughly since then and have had no further problems.
