Seven cleaners were selected from the laboratories database of past testing based on supplied data from client. Two client supplied products were included as well. All products were diluted to 5% using DI water in 600 ml beakers. All nine products were heated to 120 F on a hot plate. Twenty-seven preweighed aluminum coupons were coated with client supplied coating, Castrol Industries Rustilo 4163 (64742-46-7, 8002-74-2, 34590-94-8), using a hand held swab and then weighed a second time to determine the amount of soil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. Coupons were rinsed in tap water for 15 seconds at 120 F, followed by air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.
All nine products removed over 92% of the rust preventative coating within the five minutes of immersion cleaning. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
