Trial Report



Trial Number 12

(Client Number 318, Project Number 1)

Trial Purpose: To test Alpha Blue Care for all purpose cleaning

Date Run: 02/15/11

Experiment Procedure:
The supplied cleaning product was diluted with DI water at room temperature to vendor recommended concentration
for all purpose cleaning (2 oz per gallon or 1.56%). A comparative product was used at a standard 2% dilution rate.


Preweighed ceramic, plastic G-10 and painted steel coupons were coated with Hucker's Soil Formulation (Jif 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.

Trial Results
The supplied product was more effective at removing the Hucker?s soil from the three surfaces using manual wiping than the non-green comparative
product, removing more than 85% of the Hucker?s soil. The table lists the amount of soil added, the amount remaining after cleaning and the calculated
efficiency for each coupon cleaned.
