Trial Number 1

Trial Purpose:

To evaluate the effectiveness of odor removal of cat urine on carpet.

Date Run:

08/12/2021

Experiment Procedure:

Clean carpet was cut into eighteen 2 in x 1 in rectangular strips. These strips were placed into glass bottles and the cat urine was directly applied to the carpet (about 2ml). The cat urine had been aged for 2 days to determine dirty odor characteristics. A panel of five people examined the odors to determine the baseline values using 18 bottles, including three controls.

Each panelist was asked to describe the aged cat urine odor carpets and to rank the level of intensity of the malodor; from 1 being no malodor to 5 being high malodor levels. Afterwards, each bottle was subjected to rounds of cleaning agent treatment, one treatment cycle consists of 2 sprays and each panelist was used to assess malodor levels after each cycle of treatment. One of the five cleaners were each assigned to a set of three carpet strips out of the eighteen carpet strips total. Treatments of contaminated bottles are stopped after three treatment cycles. The bottles were then allowed to age overnight. Following the overnight sit, panelists were asked to determine the bottles’ malodor ratings to obtain an increase in malodor baseline from the day after it was treated. The bottles were subject to one last treatment cycle before the final set of malodor ratings were performed. An effective cleaner will have a malodor level of under 2 after the 3rd round of treatment.
