To analyze the efficiency of Gain Dishwashing solution in the removal of Hucker's soil from various substrates
Date Run:
05/05/2021
Experiment Procedure:
Gain dishwashing cleaning solution was created by mixing 1/3 gain dishwashing solution and 2/3 water. This solution was put into a spray bottle for easy application to coupons. 3 coupons of each substrate were selected (ceramic, plastic, and painted metal) and initial coupon weights were recorded. Hucker's soil (Creamy Peanut Butter, Salted Butter, Wheat gluten, Egg Yolk, Evaporated milk, DI water, Printer's ink with boiled linseed oil, India Ink, Saline Solution) was administered to each coupon, and was allowed to air dry for 2 hours. Contaminated weights were recorded once all coupons were dried for the 2 hours. 3 coupons of each substrate were placed into the SLW machine while a Wypall cleaning cloth was fixed to the cleaning block. The Gain dishwashing solution was administered to each coupon and the Wypall cloth with 2 sprays on each. The SLW machine was run for 20 repetitions, simulating 20 manual wipes. Coupons were removed from the SLW machine and allowed to air dry for 24 hours. After 24 hours, clean weights were recorded.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Conclusion:
Gain dishwashing solution removed 84.5% of Hucker's soil from ceramic coupons on average, 92.1% of Hucker's soil from plastic coupons on average, and 89.4% of Hucker's soil from painted metal coupons on average. Overall, Gain dishwashing solution removed 88.7% of Hucker's soil from all substrates on average
