By my experience, ultrasonic cleaners work great with weak solvents (isopropyl alcohol, methanol, that type of thing) for degreasing. Detergent solutions are fine, but with anything that is more aggressive, be cautious. They start etching pretty fast with mild to stronger acids, like evapo-rust. If you try those, go with short cleaning times initially, until you see how a particular solvent behaves with the parts that are being cleaned.
