Control testing to monitor hucker's soil consistency.
Date Run:
12/14/2021
Experiment Procedure:
Nine pre-weighed coupons were contaminated with 0.5 grams of Hucker’s soil (Evaporated Milk; 26.5%, Creamy Peanut Butter; 17%, Salted Butter; 17%, Stone Ground Wheat Flour; 17%, Linseed Oil; 2.25%, Saline Solution; 5.25%, India Ink; 6.8%, Lemon Juice; 8.2%). Coupons were aged for two hours at room temperature (68°F) before dirty weights were recorded. Coupons of the same substrate were placed into the Straight Line Washability (SLW) unit, three at a time, and treated twice with water. A Wypall was attached to the SLW sled and was also treated twice with water. Each test ran 20 cycles (~30 seconds of cleaning). Coupons were air-dried at room temperature (68°F) overnight before final weights were recorded.
