Gravimetric

Three coupons of each substrate were used per cleaning product, for a total of 24 coupons.  Each coupon was weighed using a gravimetric balance and had their weights recorded.  Each coupon was then soiled with about 0.5 grams of lithium grease by using a swab to administer the contaminant down the center of the coupons.  Each coupon was then weighed again and had their 'dirty weights' recorded.  The coupons were then cleaned with their respective cleaning product using the Straight-Line Washability Unit (or SLW) to ensure a standard pressure is applied to each coupon while being manually wiped.  Two sprays of the correct cleaner were applied to a wypall that is attached to the cleaning sled of the SLW to wipe the soil away and two sprays were applied directly to each coupon (meaning each coupon was cleaned with about 2.5 ml of cleaning chemistry).  The SLW unit was run for 20 cycles (20 back and forth motions) for each coupon.  Once cleaned, the coupons were allowed to air dry before having their final weights recorded.

None of the products are effective in removing lithium grease from Aluminum, Galvanized Steel, or Stainless Steel.  The Fomula 409 and Polychem Deox 007 performed comparatively and removed, on average, about 50% of the soil from the coupons.  The GeoPro X 1.5% concentration unfortunately did not perform comparatively to the two other products, removing only about 6.2% of soil from the coupons.
