Cleaning Investment from castings

John, I use a product called GYPSOF made by Zero-D Products. It not
only softens the investment for easy removal, but actually brightens
the castings too! I also use it as a mild Pickle in my ultrasonic so
that makes it an even better value. Call their sales staff at:
