Laboratory evaluations of alternative cleaning products
Date Run:
05/26/2004
Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
All products were used heated to 96 F on a hot plate in 250 ml beakers. Eighteen preweighed steel coupons were coated with a varnish mix containing Cooper's Creek Chemicals, Cooper Black Tank Paint No 739 (64742-89-8, 8052-42-4, 108-88-3); Sherwin Williams Company, V74B2 Black Asphaltum coating (64742-89-8, 64742-88-7, 8052-42-4) using a handheld 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.
