Trial Number 1

Trial Purpose:

To evaluate three products for all purpose cleaning

Date Run:

11/15/2013

Experiment Procedure:

Plastic, Ceramic, and painted metal coupons were weighed and then coated with Hucker's soil using a hand held swab and allowed to dry for 2 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 1 spray of cleaning solutions. Each coupon was sprayed once with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). At the end of the cleaning, final weights were recorded and efficiencies were calculated.

The Toucan Eco product was run through two cycles using 1 gram of salt and 1.5 liters of water at 120 F. Resulting free chlorine level and pH were recorded. The supplied NaOH was used at room temperature and 120 F.

ChemistriesEvaluated: Toucan Cleaner (1 g salt/1.5 L - pH 8-9; Free Chlorine 100 ppm); NaOH at room temp and 120F;

Trial Results:

The heated NaOH solution provided removed more than 80% of the Hucker’s soil from the surfaces using manual wiping. At room temperature, it removed 77% of the soil. The Toucan Eco heated removed just under 70% of the soil. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each coupons cleaned. Photographs of cleaned coupons are included.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

Using manual wipe, the three products were more effective in removing Hucker’s Soil than water.
