There are no related objects.
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.

Testing had potential. At first, the soil was dissolved but once it was taken out of the soil it was apparent that the soil had left behind residue. The best cleaner was the Vertrel Sion which was able to quickly dissolve the soil and caused minimal streaking. FluoSolv NC and Solstice PF were not very successful, leaving behind a significant amount of residue behind. In general, the best cleaner for the job was Vertrel Sion.
