Same basic idea, but maybe easier to locate is Lemishine. It's in the grocery store with the dishwasher detergent, used for cleaning all the crud out of a metal tub dishwasher. It's cheap...and a spent 45acp case full is all it takes to do a a very full load of brass in the Lyman wet tumbler.
One thing to add - if you aren't going to lube and size right away, put a few drops of oil on your fingers as you handle your cases to put away for storage...otherwise you'll get green spots after a few weeks.
