Three sets of three pre-weighted aluminum coupons were soiled with their respective contaminants using a cotton swab. Each set of coupons were immersed into a beaker with Surface Cleanse 930 at a concentration of 5%, for 15 minutes at a temperature of 120° F. During this process, any noticeable soil removal was observed. Coupons were dried with a heat gun as well as with a manual wipe afterwards, to inhibit the cleaner creating visual damage to the substrates. After drying, final weights were recorded, and efficiency was calculated for each coupon cleaned.
