I have a Chicago Eletric Ultrasonic Cleaner. I purchased the smaller one to see if it works on brass casings.....boy does it do good job!
50% vinagar and 50% water and a dab of dish soap and they look new after 30 minutes! never will go back to tumbler again!

Bush Man, from whom did you purchase your cleaner?--direct form Chicago Electric?

It osunds like just the trick, also, how big is this cleaner, how many pieces of brass do you do at a time????

Thanks for the info--Don

I have used the ultra sonic cleaner at work seceral times with different mixes and never seemed to do much better then just mixing vinegar water and soap and letting it set. I went back to using my tumbler.
