All of Coyuchi's organic cotton products are machine washable. We recommend machine washing on the gentle or delicate cycle with like colors, with cold water and a natural, plant based laundry detergent. We do not recommend using whiteners, as bleaching agents may diminish the brilliance and depth of the colors; when needed, use only non-chlorine bleach. Line dry, or tumble dry low and remove promptly. Fabric softeners and dryer sheets reduce the absorbency of cotton textiles and are not recommended. Place a set of our wool dryer balls inside the dryer to naturally soften the fabric and reduce drying time. Use a warm iron as needed.
