Trial Number 1

Trial Purpose:

To evaluate cleaning method using food based substrate

Date Run:


Experiment Procedure:

The soil mixture used a teaspoon of AATCC Carpet soil added to 50 ml of mineral oil and shaken to mix it up. The soil was using a plastic squeeze pipette. Approximately 0.03 to 0.05 grams of soil was added to a precleaned piece of fruit/vegetable. The fruit/vegetable was weighed with the dirt to determine the amount of soil added. The dirty fruit/vegetable was cleaned for 20 seconds using immersion and mild agitations (up and down dunking). Final weights were recorded and the percent soil removal was calculated. Test evaluation was run in triplicate. Water was used as a control.

Trial Results:

Soil removal on the food surface was more successful for the cleaner than with water.

Success Rating:

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


The testing methodology at the shorter time (20 seconds in place of 30) resulted in the cleaning product removing slightly more soil than water alone. Next phase of testing will be done using supplied product.
