Water with a few drops of dish soap. Don't leave plastic parts in the
ultrasonic cleaner for very long, they'll start to look bad (I think the
word is "craize"). A few minutes should be sufficient - plastic doesn't
get as nasty as brass, usually. If your ultrasonic cleaner has a power
control, turn it to minimum.

I've never done that. I just put the parts into the basket. I can see
where using a small container would help with very small parts (like HP
air spools). As long as the sound (pressure) waves make it through the
containers, it should work. In that regard, I'd expect plastic drink
cups to be better than glass. I'd be a little concerned with glass
braking, too. You still need to make sure the tank is filled with a
liquid to the proper depth. If you're not cleaning anything directly in
the main tank, the dish soap is probably not necessary.

I was told by several shops that the strong (acidic cleaners) would attack
the main tank, that's the reason I was given for using water with a small
amount of detergent in the main tank and other containers to hold the harsh
cleaners inside the main tank.

Over time, a strong acidic solution might destroy the stainless steel tank.
But you don't need to use a strong solution. If you don't let your gear
get completely crudded up, you probably don't even need to use an acid.
