How to Clean Mold Release Agent from HDPE parts?

Q. We are looking for a product that will allow us to clean mold release agent from the surface of molded HDPE parts. A.

Industrial Ultrasonic Cleaning: Detergent Bath Life

Q: We manufacture medical devices. Can we use our Alconox or Citranox bath solution more than once? How do we know that we need to change the solution?

A: For the highest level of cleanliness, you only use a solution once. In general, in a medical device manufacturing and cleaning operation, a detergent bath will typically easily last for 8 hours.
