I don't have anything big enough to contain chainrings or cassettes for cleaning so the glass jar approach is out, although the bag idea sounds promising. I might just give that a try, it will also mean I can hopefully get away without needing a gallon or more of cleaning solution.
I guess tomorrow it's off to the bike shop, I don't have much cleaning solution left at the moment.
I know you said your tank is large enough to fully submerge the chainring, but I was thinking of my smaller tank (the one many use from HF) and the issue of having to rotate chainrings (doing half at a time). I had a thought. It seems one could completely fill a gallon size zip lock with cleaner solution, drop in the chainring(s), and then drop the bag it into the smaller ultrasonic tank of water. The full bag would extend above the cleaner's tank's top. Would the ultrasonic waves still penetrate the entire bag's contents, or just the portion below the water level?
