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 testing of various cleaners on aluminum, concluded that FluoSolv CX was the best cleaner, followed by the Honeywell Solstice PF product. The oil was very lightweight and thus came off quite easily. There were some cleaners which removed the cleaner but left behind some residue or film on the coupons. Unlike with other testing, the DuPont product did not perform as well as it usually does.
