Gravimetric

Three pre weighed aluminum coupons were used per cleaner for a total of 9 coupons.  The coupons were then soiled with a mixture of 1 teaspoon of AATCC synthetic soil and 50 mL of mineral oil by swabbing the mixture onto the bottom third of the coupons.  The dirty weights of the coupons were then recorded.  The coupons were then cleaned with their respective cleaners by a singular wipe of a paper towel wet with the correct cleaner.  The coupons were then left to dry for 20 mins before the clean weights were recorded.
