Trial Purpose:

To evaluate the effectiveness of Dr. Easy and Rejoice brand cleaners on the elimination of unwanted odors.

Date Run:

02/07/2019

Experiment Procedure:

A total of six clean glass bottles were each filled with six milliliters of whole milk. Four of these bottles would be treated by formulations and the remaining two bottles would be used as controls. All bottles were capped and stored in a room for a little over a week at room temperature (68F). After the spoiling period, the bottles were opened and a panel of five observed for signs of spoiling odor, according to the rating system (see below). Two bottles were reserved for each formulation, and two shakes of the respective formulations were applied to the soiled carpet, left for five minutes and then vacuumed. After vacuuming, the odor panel graded each bottle with their ratings recorded. This process continued by introducing two shakes of powder into each bottle of its respective formulation and rating until six total shakes were reached. The bottles were stored once again at room temperature and sat overnight. All testing bottles were rated the next day with no treatment, and then an additional two shakes were added before final ratings. 

The following rating system was used to assess the malodor of the spoiled milk:

Rating key:
1 No Malodor
2 Slight Malodor
3 Noticeable Malodor
4 Considerable Malodor
5 Severe Malodor
