Aqueous Ultrasonic cleaning really needs hot water and some type of non-sudsing surfactant additive. Greasy parts don’t clean well. Ultrasonic sound waves get absorbed by grease and kill the cavitation cleaning action. Solvents work best in those situations. Bigger than bench top ultrasonic cleaners are available but pricey. Mostly sold for automotive (transmission repair, radiator cleaning) and large variety of specialty industrial cleaning. I made and sold them in an earlier life.
