Four cleaners were tested at room temperature on aluminum, brass, and stainless-steel coupons to evaluate how the soil Navi Guard Way Lube 32 was cleaned. Preweighed coupons were coated with the supplied Navi Guard soil using a handheld swab 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 sir 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.

All four cleaners efficiently removed the Navi Guard soil on all three substrates at room temperature. The least efficient cleaner used was Solstice 2A from Honeywell, with the lowest cleaning average on the stainless-steel substrate. The Solstice 2A was still an efficient cleaner with a 97.52% efficiency but was less efficient than the other cleaners used. The most efficient cleaner would be Solstice PF from Honeywell which had an efficiency of 98.48%. All cleaners worked extremely well.
