We are fanatics about the proper care of our beloved woolens and cashmere. THE LAUNDRESS Wool & Cashmere Shampoo was developed by combining cedar extracts and sulfate-free shampoo to clean and preserve the natural components of the yarns. This product can be used for both hand and machine washing. THE LAUNDRESS Cedar scent is perfect for both everyday washing and added care for seasonal storage. Save your sweaters and your wallet!
