Professional cleaning is recommended. If cleaning at home, machine wash warm water, gentle cycle, with mild detergent; use an extra rinse cycle. Dry on medium heat; 2 to 4 cycles may be needed. Add a dryer ball for additional assistance, and reposition the items in the dryer between cycles. As the cotton shell will dry faster than the down filling, press down to test the dryness of the filling. Use an additional drying cycle if needed to completely dry the down; this is critical.
