I paid a lot of money to Decker's Carpet Cleaning for specialized cleaning that included pet odor elimination. The carpet looks good but it still has a bad smell from my animals. I'm not sure why I paid so much money for their special service when I could have hired a regular carpet cleaner for the same result. I don't know anything about the science of carpet cleaning, but I do know I am not seeing much of a difference. The technician was very nice but even he told me upfront the specialized technique might not completely work. Fortunately, the carpet cleaning is just a stop-gap measure until I can replace the carpeting with new flooring. In the meantime, I guess I'm just going to have to live with it. I'm just sorry I paid so much extra money.
