Jon,
How do you heat your ultrasonic bath? Ours is small, 6x6x10, and has a water jacket but no heating element, just an inlet and outlet tube. Picked it up from a silicon chip maker that must have had a hot water source. Our vapor degreaser came from the same source and it cleans parts so clean that some can bond together with cohesion. Dawn detergent has put GoJo and other cleaners out of business in our shop.
