I want to get one of those Hornady ultrasonic cleaners. Faster, quieter, and cleans the inside and outside of every case beautifully.
or you could do what i did and grab the tread mill that the wife didn't use and made and tumbler out of that,cheap and nice
Try a Lee case trimmer (sans the cutter) chucked into a portable drill. Spins the case around so you can apply a little Flitz polish with a rag. Much faster than polishing each case by hand. By the way, the above trimmers are inexpensive.
