The cleaning solution was used at full strength in a 600 mL beaker. The solution was heated to 130oF. Coupons were cleaned for five minutes. Rinsing was performed for two minutes using tap water at 120oF and air dried for about two hours also at room temperature. After drying is complete, final weights are recorded and efficiencies are calculated.
SUBSTRATE MATERIAL: Stainless Steel (202-316B-80)

The Engine Degreaser was very successful in removing the adhesive and the oil from the stainless steel coupons. It was ineffective on the ink. Table 2 lists the calculated efficiencies.
