Coupons of stainless steel and copper were selected and arranged on trays, so that each cleaner had an assigned set of each surface. Before taking initial weights coupons were wiped down with Kimwipes. After taking weights the coupons were promptly soiled and reweighed. All cleaners were gathered in respective bottles and beakers. A stir bar was used in conjunction with a heating plate equipped to stir the solutions. The coupons were added to the beakers three of a kind at one time, and then allowed to sit in the stirred solution at room temperature for 5 minutes while observations were taken. Finally, clean weights were taken at the end of all the testing.

Results for percent of contaminant removed were well in the upper nineties. Visually, the results were very good. Some coupons showed signs of streaking and an apparent film. Most of the soil was dissolved in less than 5 minutes. Although, all cleaners performed well, the best results were obtained from Vertrel Sion which caused the least amount of streaking.
