Trial Purpose:
To evaluate the effectiveness of Better Life Wipes and comparative products for removing Hucker's Soil on Ceramic, Plastic and Painted Metal coupons.
Date Run:
07/01/2019Experiment Procedure:
Nine pre-weighed coupons, three of each substrate per cleaner, were soiled with 0.5g 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%) and aged for two hours at room temperature (68˚F). Dirty weights recorded before placing three coupons of the same substrate onto the Straight-Line Washability (SLW) unit. The cleaner wipe was attached to the SLW sled and cleaned for 20 cycles (equivalent of 30 seconds of manual cleaning). Coupons air dried at room temperature (68 F) overnight before final weights were recorded.
