Anyone use an ultrasonic cleaner to clean their guns with?

I have tried it on fishing reel parts with success, seems like it ought to work just fine on the hunting stuff.

I've used a smidge of dawn in the water. And acetone for really saltwater-crudded parts. But maybe guns are different (rust on non-coated metals, blueing, etc.)

Any alternative tips/lessons learned appreciated.
