Hello All:

     Will acetone work well in an ultrasonic sleaner?

You can use acetone in ultrasonic cleaner, but take good precautions because it's stinky and volatile.
I recommed to put the acetone in as small jar as possible, glass or plastic, to house the part you're cleaning and immersing the jar in the US filled with warm water.
But don't expect miracles, in case you want to clean that dried castor you mention in the other thread. It may loosen up but it also may dry the residue to an even harder sediment. L
