Trial #12
To evaluate successful products on second supplied contaminant
Nine cleaners were selected based on client request for vapor degreasing solvents. All products were used heated to 96 F on a hot plate in 250 ml beakers. The process utilized no water rinse and only used ambient air to dry the parts.
Twenty-seven preweighed steel coupons were coated with Rochester Midland RI780 rust preventative (80252-41-3, 95-63-6) using a hand held swab. The oil was then heated with a Master Appliance Heat gun at 300 F for 10 minutes. After cooling to room temperature, a second weighing was performed to determine the amount of soil that was added. Three coupons were cleaned in each solution for 5 minutes with minimal stir-bar agitation. After drying, coupons were weighed a final time to determine the cleaning efficiency of each product.
All nine products removed over 90% of the soil during the five minutes. Four of the products removed over 97%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon.
