What cleaning solution with an Ultrasonic brass cleaner?

[Fossil4Life]

Does anyone have a good recipe or favorite product they use for cleaning their brass with an ultrasonic cleaner?

Citric acid and hot water ( lemi shine ) is my favorite

I use the one shot stuff, but I bet the lemi shine works just as well.
I don't get hung up on shiny brass, just clean

50% water, 50% vinegar, a few drops of dish washing soap. Add (any brand) brass case cleaner if you want it really shiny. Rinse with plain water, then rinse with a baking soda/water solution to neutralize the acid in the vinegar, rinse again with plain water. Lay out on an old towel until dry, or put on a baking or pizza pan in the oven on very low heat if you're in a hurry. (Cover the pan with foil... don't want any kind of residue getting on your cookware.)
