Eighteen pre-weighed coupons, three of each substrate per cleaner, were soiled with half a gram of glass soil (51.5% water; 25.6% hair gel; 10.4% toothpaste; 5.3% shaving cream; 3.7% hair spray, and 3.5% spray deodorant) distributed onto each coupon using a swab. Dirty weights were recorded after the coupons had dried for 24 hours at room temperature (68° F). Three coupons of the same substrate were aligned into a Single Line Washing Unit (SLW) with Wypall X60 attached to the cleaning sled. The Wypall X60 reinforced wipe along with the coupons were all sprayed two times with water after a small amount of the cleaner was added to each coupon; then the coupons were allowed to soak for 30 seconds. Afterward, the SLW was activated, and the coupons were cleaned for 20 cycles following an additional 20 cycles where a new Wypall was placed on the sled and sprayed again twice with water. Cleaned coupons dried overnight at room temperature before the final weights were recorded.

Both cleaners were effective for the removal of glass soil from all three substrates. The Pink Stuff was 98% effective for mirror and 99% effective for glass and chrome. Soft Scrub was 99% effective for mirror, glass, and chrome.
