Trial Purpose:
To evaluate the effectiveness of Annie’s All-Purpose cleaner to a comparative product at removing Hucker’s soil from various substrates.
Date Run:
08/20/2019Experiment Procedure:
Eighteen pre-weighed coupons, three per substrate for each cleaner, was contaminated with ~0.05 - 0.1 gram 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%) for each cleaner. Coupons 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 time, and treated once with the cleaner. A Wypall was attached to the SLW sled and treated twice with the cleaner. Each test ran 20 cycles (~30 seconds of cleaning). Coupons air-dried at room temperature (68°F) for one hour before final weights were recorded.
