To test nontoxic industrial cleaning solutions for oil removal.
Date Run:
07/13/2016
Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
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 handheld 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 Environmental Products Soy Gold 1000 and Soy Gold 2000 were diluted to 5%. Each cleaner was put in a beaker and three coupons of 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.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Conclusion:
AG Environmental Products Soy Gold 1000 efficiently removed Navi Guard Way Lube 32 on all three substrates at room temperature with an efficiency of 78.80%. 5% Alconox Inc. Liquinox least efficiently removed Navi Guard Way Lube 32 on all three substrates at room temperature with an efficiency of 61.59%.
