Ultrasonic Cleaner Fluid

[Mayhem]

I've used the Lyman brass cleaner and was surprised at how good the results were.  Generally I just use hot soapy water but have found cloudy ammonia in water to be good also.  Sometimes I place parts in a jar of solvent and then place that is the bath, which also works.  Same as the plastic bag I guess.

For bearings, I have an old chip fryer that rotates the basket (supposedly stops the chips sticking together) and I run it with transmission fluid in it.  Does a good job of cleaning the bearings but I have to leave the lid open.  On the lowest setting the temp gets too hot with the lid closed and smoke pours out of the vent.
