Client Number 312

Project Number 1

Trial Purpose:

To evaluate new formulation for all purpose cleaning following GS 37 requirements.

Date Run:

10/27/2009

Experiment Procedure:

The supplied cleaning product was used at the supplied concentration (4%). A second product, selected by the lab, was used at the vendor supplied concentration. Preweighed ceramic 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 handheld 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 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 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:

Both the supplied product and conventional product were ineffective in removing the Hucker's Soil with a manual wiping action. The table lists the amount of soil initially added and the amount remaining after cleaning and the product efficiency for each coupon cleaned.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

The supplied product had an overall average efficiency less than 85% and would not be considered effective based on the SSL testing methodology for all purpose cleaning. A follow up test will be conducted using a higher concentration for the supplied product.
