Trial Number 0

(Client Number 341, Project Number 1)

Trial Purpose: To evaluate the cleaning ability of supplied product for toilet cleaning against similar products

Date Run: 12/16/10

Experiment Procedure:
Pre-weighed ceramic, porcelain coupons were coated with Hucker's Soil Formulation (Jiffy creamy peanut butter, salted butter, Arrowhead Mills stone ground wheat flour, egg yolk, evaporated milk, distilled water, printer's ink with boiled linseed oil, Shaws saline solution) using a hand held swab and allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added.

Three coupons were placed into a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds).

At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.

Products were selected based on toilet bowl cleaning needs and health and safety options.

Trial Results
The current TMI product beings used for toilet bowl cleaning had the best performance for the removal of the Hucker's soil using manual wiping. The PC
120 from MD Stetson had the next most effective product. The table lists the amount of soil added, the amount remaining and the percent effectiveness
for the four product tested.
