Carpet cleaners are used to clean soiled carpets as well as eliminate the odors caused by the soiling. A study was conducted to investigate the difference in odor removal effectiveness of three carpet cleaners. Small sections of carpeting were soiled and then cleaned. Assessors observed a soiled section of carpet (control) as well as the three sections cleaned with the different cleaners. The assessors reported the odor character descriptors observed as well as the relative strength (1 = faint to 5 = strong) of each character.
