Wet Tumbling

I used Dawn and a pinch of Lemishine for years but switched to a car wash liquid a couple of years ago and it does well without any water spots. Also leaves a slight film of wax which prevents tarnish during storage. I also used to dump the wet, rinsed brass in a flannel pillow case and give a good shake for a couple of minutes to dry which worked fairly well but upgraded that process to a Frankfort Arsenal dehydrator that I picked up on sale for $50ish a couple of years ago.

Less expensive??
My gallon of carwash liquid has lasted several years so far and has years left in it. If I had to guess I'd say it has washed 40 to 50K cases. If you're worried about a few dollars difference every 3 to 5 years your budget is a LOT tighter than mine and I'm a cheapskate LMAO
