Three pre weighed aluminum complex mesh parts were used as coupons. The coupons were soiled by swabbing the bottom third of the coupons with water coolant. The dirty weights of the coupons were then recorded and visual rankings according to the key shown below were recorded. The coupons were then subjected to a one-minute heated cycle at 140 degrees F in the VCN using Suma Break Up Heavy Duty Foaming Grease Release Cleaner 1% concentration. The coupons were then removed and left to air dry overnight. The next day the clean weights of the coupons were recorded, and visual rankings were recorded.
