Trial Number 42

Client Number 232

Project Number 1

Trial Purpose:

To evaluate requested products for all purpose soil removal

Date Run:

10/22/2007

Experiment Procedure:

The supplied cleaning products were used at full strength.

Preweighed fiberglass, ceramic and chrome coupons were coated with SSL Soil 3 (Hucker's Soil: Distilled water 45.8%, Evaporated milk 13.8%, Creamy peanut butter 9.2%, Salted butter 9.2%, Stone ground wheat flour 9.2%, Egg yolk 9.2%, Printer's ink with boiled linseed oil 0.9% and 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-Clark 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 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 top cleaning product removed less than 70% of the all purpose Hucker's soil. The table lists the amount of soil added, the amount remaining, the efficiency for each coupon cleaned and the average removal from each substrate type.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

None of the products evaluated were found to be effective. Upon review of the trial, the soil formulation was very old (over 1 year) which may have affected the cleaning performance for the conditions typically used for all purpose cleaning.
