Trial Number 0

The supplied ingredients were mixed according to the supplied procedures, substituting new surfactant into process. The end product was diluted 1 part solvent solution to 32 parts water. The cleaning products were diluted with DI water. A conventional product was diluted 1:48 (~2%).

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.

Each replacement surfactant mixtures were effective at removing the Hucker’s soil from the three surfaces using manual wiping. Each removed more the current formulation. Three surfactant mixtures removed more than the conventional comparative product (94%) and the other 3 removed around 90% of the soil. The control product removed 88%. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupon cleaned. The conventional product removed 93% of the soil.

All possible replacement surfactant mixtures removed over 85% of the Hucker's soil, compared well with the conventional product and outperformed the supplied control product.
