Trial Report



Trial Number 15

(Client Number 275, Project Number 1)

Trial Purpose: To evaluate the two supplied products for all purpose cleaning using manual cleaning.

Date Run: 01/05/10

Experiment Procedure:
The supplied cleaning products were used at the delivered concentrations. One product was tested at three concentrations (2, 1, 0.5%) and the second product was used at one dilution (1:600). Preweighed ceramic, plastic and painted steel coupons were coated with Hucker's Soil Formulation (Jif Creamy Peanut Butter 9.2%, Salted Butter 9.2%, Arrowhead Mills stone ground wheat flour 9.2%, Egg Yolk 9.2%, Evaporated milk 13.8%, Distilled water 45.8%, Printer's ink with boiled linseed oil 0.9%, Shaws saline solution 2.7%) 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 Klark Wypall X60 reinforced wipe 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 solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and efficiencies were calculated and recorded.

Trial Results
The table lists the amount of soil added and the amount remaining after cleaning and the product efficiency for each coupon cleaned.
