Client Number 232

Project Number 1

Trial Purpose:

To evaluate supplied product on three substrates for Hucker's Soil removal.

Date Run:

08/06/2005

Experiment Procedure:

The three supplied cleaning product were diluted with DI water to vendor recommended concentration for all purpose cleaning. 

Nine preweighed ceramic, nine plastic G-10 and nine 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. Photographs were taken.

Three coupons were placed into a Gardner Straight Line Washability unit. A Professional Painter's Rag 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:

All three products were successful in removing SSL Soil 3 - Hucker's Soil from ceramic, plastic and painted steel coupons. Table 1 lists the amount of soil applied and removed for each substrate and coupon.
