I bought an ultrasonic cleaner after reading reviews and post on another website 6mmbr.com. The machine cost $28.99 from Harbor Freight Tools. The Detergent I bought is called Citranox. A citrus detergent concentrate. By concentrate I mean you can take one gallon of it at make up to one hundred gallons of solution. So for $36 your set for a very long time. So I have been doing alot of shooting and reloading lately, and of course brass cleaning and am quite happy with the results. I am allergic to tumbler media (walnut) so this is the perfect solution. This little unit has a one pint capacity so i can only do 5-10 25-06 Ackley cases at a time. There is tons of info on this subject on 6mmbr.com so check it out if you are interested.
