Trial Purpose:
To evaluate three supplied products for all purpose cleaning following DfE requirements
Date Run:
04/09/2012Experiment Procedure:
The supplied cleaning product was diluted with water at room temperature to vendor recommended concentration for all purpose cleaning (128:1). The comparative product was used at the provided concentration.
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:
White Water resulted in removing 93% of the Hucker’s soil within 30 seconds of cleaning and was found to be more effective than the comparative product. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupon cleaned.
