For best results, wash your down & feather duvet on a delicate warm water cycle (60°C or 140°F). Use only one-third of the normal amount of detergent and wash it separately from another laundry. If possible, put it in the tumble dryer as soon after washing as you can. Set the tumble dryer to air or low heat settings.
