Trial Purpose:
To evaluate three supplied products for all purpose cleaning following GS 37 requirements
Date Run:
08/12/2014Experiment Procedure:
Three sets of nine ceramic, stainless steel, and polycarbonate coupons were weighed and then coated with the 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%, saline solution 2.7%) using a handheld swab and allowed to dry for 2 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 x60 reinforced paper towel was attached to the cleaning sled and soaked with 1 spray of cleaning solution. Each coupon was sprayed 1 time with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). Final weights were recorded, efficiencies were calculated and recorded.
ChemistriesEvaluated: Zbioscience A1+; Clorox 409; Greenworks;
Trial Results:
All three products were effective at removing the Hucker’s soil from some surfaces using manual wiping. Zbioscience resulted in the lowest efficiency average, removing just below 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.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Conclusion: Greenwork All Purpose was found to be most effective for removing the Hucker’s soil from various surfaces using manual wiping with a 91% average. Zbioscience was effective in removing Hucker’s soil from plastic but not from painted aluminum or ceramic.
