Trial Number 15

Trial Purpose:

To evaluate three cleaners on second contaminant using vapor degreasing

Date Run:


Experiment Procedure:

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. Nine preweighed steel coupons were coated with Rochester Midland RI780 rust preventative (80252-41-3, 95-63-6) using a hand held swab.  The oil was then heated with a Master Appliance Heat gun at 300 F for 10 minutes.  After cooling to room temperature, a second weighing was performed to determine the amount of soil that was added. Three coupons were cleaned in each solution for 15 minutes in the bench top vapor degreaser.  After cooling, coupons were weighed a final time to determine the cleaning efficiency of each product.

Trial Results:

All three products removed over 99% of the oil within 15 minutes of degreasing. Observations note that most of the oil was removed within the first 5 minutes of vapor exposure.  The table lists the amount of soil added, the amount remaining and the efficiency for each coupon.

Success Rating:

Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.


The same products will be evaluated under the same conditions for the varnish contaminant.
