Three products were selected based on results from previous trials. All products were used heated to 160 F on a hot plate in 250 ml beakers. One product, Solvon PB, cleaned one part with the metal working fluids (Quench Oil, RI 780) for 15 minutes in the vapor degreaser. The other two products cleaned two parts, one with Quench oil and the other with the varnish mix. Each part was cleaned in each solution for 15 minutes in the bench top vapor degreaser.
