Twenty-Two sets of stainless-steel coupons were weighed, each set consist of three coupons. The first eleven sets were soiled with GS 34 Soil-1 and the other eleven sets were soiled with GS 34 Soil-2. Both soils were applied at the loading of ~100mg. The soiled coupons were oven dried for 30 minutes with 40 °C for GS 34 Soil-1 and 105 °C for GS 34 Soil-2. Dirty weights were recorded for all of coupons after 15 minutes of cooling.

Three coupons were placed into a Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of cleaning solutions. Each coupon was sprayed 1 time with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~33 seconds). Final weights were recorded the following day. Efficiencies were calculated and recorded.

Soil 1: Maintenance soil = 10 grams of carbon black, 10 grams iron oxide, 100 ml WD-40, 100 ml hydraulic oil, and 100 ml gear oil.
Soil 2: Production soil = 200 ml Quench Oil and 200 ml cutting oil
