Three sets of pre-weighed aluminum, ceramic, and polycarbonate coupons were soiled with a half a gram of Lithium White Grease using a hand held swab. Contaminated weights were taken and then three of the same type of coupons were immediately placed into a Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with one spray of desired cleaning solutions. Each coupon was sprayed once with the same cleaning solution. All cleaning solutions were diluted to the recommended percentages. The solution was then allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles.
