cleaning cases
I load in small lots, 20 at a time, and I wipe the cases with a "blue" paper towel dampened with ISO (isopropyl alcohol, 99% pure). Since I've started doing this my cases look nice, don't seem to tarnish and my tumbles gets less use.
The cheapest source for ISO is a pharmacy, usually behind the counter marked rubbing alcohol. Try and get 99% pure. (Costco)
Another benefit, good solvent and safe, it's rubbing alcohol.
