To evaluate two cleaners on the effectiveness of removing bathroom soil from ceramic, plastic, and chrome surfaces.
Date Run:
10/30/2019
Experiment Procedure:
Eighteen pre-weighed coupons, three of each substrate for each cleaner were contaminated with 0.5 grams of bathroom soil (28.6% All-in-one Shampoo & Conditioner, 21.4% Dry Skin lotion, 21.4% Liquid Hand Soap, 14.3% Liquid Body Wash, 7.2% Deodorant Bar Soap, 7.1% Water). The coupons were aged for 24 hours at room temperature (68 F) before recording dirty weights. Three coupons of the same substrate were placed in the Straight-Line Washability (SLW) unit and a Kimberly-Clark Wypall reinforced paper towel was attached to the cleaning sled. The Wypall and coupons were treated with two sprays of the cleaning solution and cleaned for 20 cycles (equivalent of 30 seconds cleaning). Coupons were air dried at room temperature (68 F) and final weights were recorded.
