I love WD40. As much for the internet battles it inspires as the utility it has when used as intended.

For ultrasound, I use plain, HOT water and a bit of detergent dishwashing soap will work. Yes there are better things but these will probably work well.

There is a need to get the dissolved gasses out of solution. Heat does that, but so does the initial 20 minutes of running the ultra sound.

I'm just learning to use mine (mostly for cleaning brass).

There are some good instructions and hints about using these on the web - I wish I had better marked the one I read last. But do a little searching for suggestions.
