Trial Number 331

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:


Experiment Procedure:

Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning. 

The three products were used heated to 96 F on a hot plate in 250 ml beakers.  Nine preweighed steel coupons were coated with Castrol Quench G oil (64742-55-8, 64742-65-0, 8052-42-4) using a handheld swab.  The quench 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 5 minutes with minimal stir-bar agitation.  After drying, coupons were weighed a final time to determine the cleaning efficiency of each product.
