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.

The cleaners selected worked well in dissolving the oil. There was some filming and streaking present, especially with FluoSolv CX and FluoSolv NC. Vertrel Sion and Solstice PF were the better of the cleaners, even though they did have some streaking and some residue in the case of Solstice PF. Of the two better cleaners, Vertrel Sion showed the least visual streaking.
