Trial Report



Trial Number 0

(Client Number 373, Project Number 2)

Trial Purpose: To determine whether the Force of Nature product is better at eliminating the odor of milk than a 1% bleach solution.

Date Run: 10/21/16

Experiment Procedure:
Milk was placed in several glass jars and allowed to age for 3 days. The cleaning solutions were prepared the day of use, bleach was diluted to 1% and the Force of Nature cleaner was made following the instructions provided. Although the cleaner was made three times, each time the free chlorine content was always about 750ppm and the pH was of 4.5. Testing began with three experimenters smelling a control bottle and comparing it to all other bottles. The rating system was 1-5, 5 being the worst smelling and 1 being the best smelling. Two sprays of the cleaner corresponding to each bottle were applied and then they were again smelled and rated. This step was repeated two more times for a total of 6 sprays on each bottle. The bottles were then left overnight and smelled the next day and rated. An additional two sprays were applied the day after initial testing and the final ratings were obtained.
