As a pro rug washing company, our work is often judged by not how clean the rug is, but how uniformed and bright the fringes are. But years of wear and staining can take a serious toll on the condition and appearance of fringes. At Premier Oriental Rug Washing, we use only wool-safe and cotton-safe fringe cleaners. They are acidic, preventing browning and contain no bleaching or oxidizing agents.
