To conduct performance testing on supplied product and compare with water and related industry product.
Date Run:
07/30/2020
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. In addition, a panel of three were used to visually rank the fruit/vegetable from best to worst.
Trial Results:
The supplied product was the top performer, removing over 90% of the soil. The qualitative assessment matched the quantitative removal rates.
