A Windex Glass Cleaner solution was gathered to begin testing. Then, 3 coupons of each substrate (ceramic, chrome, plastic) were collected and initial weights were taken. Bathroom Soil was applied to each coupon and allowed to air dry for 24 hours. After the 24 hour dry time, the weights of the newly contaminated coupons were measured. All coupons were placed into a Gardner-scrub Abrasion Tester machine. Wypall cleaning cloths were attached to each of the 3 cleaning blocks used for the test. Each Wypall cloth and all coupons received 2 sprays of the Windex Glass Cleaner solution and the Gardner-scrub Abrasion Tester was run for 20 repetitions, simulating 20 manual wipes. Once cleaning concluded, the cleaned coupons were allowed to air dry for 24 hours. After 24 hours, the weights of the cleaned coupons were measured.
Windex Glass Cleaner was analyzed to determine its effectiveness in removing Bathroom Soil from ceramic, chrome, and plastic substrates. Windex Glass Cleaner was found to be 88.58% effective in the removal of Bathroom Soil from ceramic, 90.01% effective in removing Bathroom Soil from chrome, and 84.67% effective in removing Bathroom Soil from plastic. Overall, Windex Glass Cleaner was 87.75% effective in removing Bathroom Soil from all substrates used in testing.
