A Spectro Guide Gloss-Color meter from BYK Gardner was used to measure baseline gloss readings from six coupons, three per cleaner before soiling with one gram of glass soil (51.5% water, 25.6% hair gel, 10.4% toothpaste, 5.3% shaving cream, 3.7% hair spray, 3.5% spray deodorant) using a swab. Coupons air dried at room temperature (68F) for 24 hours before recording dirty gloss readings. A sponge provided by EcoEgg was used to manually clean with both the supplied and comparative product. The sponge was cut into four pieces and one piece was used per cleaner. A sponge piece was saturated once with deionized water before rubbing it into the EcoEgg hard surface cleaner in a circular motion for five seconds. The coupons were cleaned one at a time for 30 seconds in a circular motion with a reapplication of the cleaner between each coupon. A dime sized drop of the comparative product was applied directly to the coupons one at a time and cleaned with a wet sponge for 30 sections in a circular motion. The coupons were dried by wiping once with a microfiber towel before taking clean gloss readings and final observations.
