Trial Number 5

The supplied cleaning product was used at two supplied dilutions, 10:1 and 20:1.

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.

Both dilutions were effective at removing the Hucker's soil from the three substrates. The 10:1 dilution was more effective on two of the three substrates, painted steel and plastic, but was slightly less effective on the ceramic than the 20:1 dilution. Overall, the 20:1 dilution had the higher average efficiency. The table lists the amount of soil added, the amount remaining and the calculated efficiency for each coupon cleaned.

Both dilutions removed over 85% of the Hucker's soil and would be considered effective based on the SSL testing methodology.
