I needed a small woven rug that had been hanging in a bathroom to be sanitized and to have odors removed. At the business you can watch the cleaning process in action. In addition, the business wanted me to know beforehand about potential hazards of cleaning such as color drift or warping. In the end, the wool rug was color-fast and no further warping occurred due to washing, however the sanitation process did not remove all of the odors.
