To evaluate all purpose cleaning formulations at a lower dilution
Date Run:
06/04/2010
Experiment Procedure:
The supplied ingredients were mixed according to the supplied procedures, substituting new surfactant into process. The 3:1 concentrate was diluted 1 part solvent solution to 32 parts water. The cleaning products were diluted with room temperature DI water.
Preweighed ceramic, plastic G-10 and 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 handheld 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:
All six replacement surfactant mixtures were effective at removing the Hucker’s soil from the three surfaces using manual wiping. Each removed more the current formulation. Each diluted version except H3HCA was less effective than the RTU products tested previously. The control product removed 84%. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupon cleaned.
