Eight cleaners were selected from the laboratory's database of cleaning evaluations. Based on client input, five cleaners could be used as a cold solvent, requiring no rinsing and leaving no residue. These cleaners were used at full strength. Two other products were aqueous based and diluted to 10% using DI water. The final was a bio-based solvent used at full strength. All eight products were used at room temperature in 250 ml beakers with no agitation. The process utilized no water rinse and only used compressed air to dry/rinse the parts. Twenty-four preweighed steel coupons were coated with Castrol Quench G oil (64742-55-8, 64742-65-0, 8052-42-4) using a hand held swab. The quench 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 no agitation. After drying with the air blow off, coupons were weighed a final time to determine the cleaning efficiencies of each product.
