Trial Number 490

(Client Number 153, Project Number 1)

Trial Purpose: To test nontoxic industrial cleaning solutions for oil removal.

Date Run: 07/13/16

Experiment Procedure:
Four cleaners were tested at room temperature on copper, brass, and stainless steel coupons to evaluate how Navi Guard Way Lube 32 soil was cleaned. Preweighed coupons were coated with each supplied soil using a hand held swab for each substrate and weighed a second time to determine the amount of soil added. Alconox Inc. Liquinox was diluted to 1% and 5%, AG Enviromental Products Soy Gold 1000 and Soy Gold 2000 were diluted to 5%. Each cleaner was put in a beaker and three couponsof each substrate 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 recorded and efficiency calculated for each coupon cleaned.
