Trial Number 4

Trial Purpose:

To evaluate three supplied products for all purpose cleaning

Date Run:

04/27/2011

Experiment Procedure:

Preweighed ceramic, polycarbonate and painted steel coupons were coated with Hucker's Soil Formulation (Jiffy 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 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:

The supplied product worked as well as the two comparative products using manual cleaning for all purpose soils. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

While the efficiency of the Orbio product (90.83% +/- 11.4) showed slightly lower performance on polycarbonate substrate, its overall efficiency when combining its effectiveness for all three substrates was above 90%. The performance was statistically the same as Formula 409 (89.25% +/-5.7) and 3R’s product (91.16% +/-9.0).
