All three products were used at room temperature. The supplied product was used at a 1:128 dilution. The green comparative product was used at its ready to use concentration. The non-green comparative product was diluted to 2% using 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.

All three products were effective at removing the Hucker’s soil from the three surfaces using manual wiping. The supplied product was more effective than the non-green product and about the same as the green product removing more than 90% 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.

The supplied product was found to be effective for removing the Hucker’s soil the three surfaces using manual wiping. It compared well to the two other cleaning products supplied for testing.
