12 stainless steel coupons were used for both cleaners being tested, for a total of 6 coupons per cleaner. The initial weights of each coupon were recorded. The bottom third of every coupon was soiled by applying the contaminate with a swab. The dirty weights of each coupon were then recorded. The coupons were then subjected to heated immersion at 125 degrees Fahrenheit in the cleaners with a 240 RPM spin for 10 minutes. After the coupons were cleaned, they were left to air-dry overnight. The next morning, the clean weights of each coupon were taken.
