Get some cheap plastic bowls that will just fit in the cleaner tank, put the brass and cleaning solution in the bowl, put the bowl in the tank, and fill the tank with water to the full mark. Run for a month or two until you decide the inside of that bowl is getting rough, toss it, and repeat. I save 1-3 lb margarine tubs, coolwhip tubs, whatever (and have asked friends to give me theirs on occasion), both to use as cereal bowls and to use in my ultrasonic cleaner. Yes, you lose just a smidge of cleaning power but the stainless steel tank will now last "forever" :-).

A friend is cleaning brass prior to reloading in an ultrasonic cleaner using an old formula-
1 qt H20
1 cup vinegar
1 Tsp salt
1 Tsp soap
Seems like a couple of the pans have corroded through on different brands of unit- destroying the ultrasonic cleaner. The brass should not be in contact with the pan (there's a stainless basket, or plastic in the 3rd one he's trying).
Any reason why this would happen? There's not that much difference between (presumably 400-series) stainless and brass on the electrochemical series.
Thanks for any leads..
