Trial #4
To eliminate the use of N-Propyl Bromide in cleaning operations.
One cleaner was tested at room temperature on aluminum, brass, and stainless-steel coupons to evaluate how Castrol Performance Bio NC Lite, Navi Guard Way Lube 32, and Water-Soluble Coolant soils were cleaned. Preweighed coupons were coated with each supplied soil using a handheld swab for each substrate and weighed a second time to determine the amount of soil added. Each cleaner was put in a beaker and three coupons were immersed into the solution for 5 minutes. The coupons were then stood upright to air dry for 15 minutes and then placed on a tray. There was no rinse. Once dry, final weights were measured and efficiency calculated for each coupon cleaned.

DuPont Vertrel Sion efficiently removed the three soils, Castrol Performance Bio NC Lite, Navi Guard Way Lube 32, and Water-Soluble Coolant on all three substrates at room temperature. The Castrol Performance Bio NC Lite soil with Sion was cleaned with an efficiency of 99.20%. The Navi Guard Way Lube 32 was most efficiently cleaned with Sion, with an efficiency of 90.43%. The Water-Soluble Coolant soil was least efficiently cleaned with Sion, with an efficiency of 90.34%.
