Trial Number 9

Trial Purpose:

To evaluate biobased cleaning products for hard surface cleaning.

Date Run:

09/25/2007

Experiment Procedure:

The identified cleaning product were diluted to the vendor's recommended concentrations for all purpose cleaning using DI water. Three preweighed fiberglass and plastic coupons were coated with SSL Soil 3 (Hucker's Soil: 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 hand held 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 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. Observations were made as well for removal rates.

A total of 38 products from 16 vendors were selected based on supplied information on potential product usage on multiple surfaces and contaminants.

Trial Results:

During the laboratory testing, the visual observations made were based on a qualitative assessment for how much of the soil was removed from the various coupons. To assess a semi-quantitative value to the visual observations, the following system was used:
100%: Coupon prior to Hucker's application
75%: Clean
50%: Slightly dirty
25%: Dirty
0%: Very Dirty

Each of the three coupons cleaned by a single product would be assessed a numerical value and then averaged for the product. These values are listed in the table below, along with the observations. Of the 72 product/dilution combinations, 34 combinations had an average cleaning level at or above the 50% mark. There were seven products with an average of 67 or greater.
