How to wash and dry your down duvet:

• To ensure that your duvet brings you comfort for many years to come, dry cleaning is recommended.
• Always use a duvet cover to keep your duvet clean and avoid unneccesary washes.
• Down duvets or comforters can be washed at home, as long as your washing machine and dryer are large enough to accommodate your duvet.
• Use a mild detergent that is hypoallergenic and without dyes or perfumes
• Use a delicate cycle with warm water. If dust mites are a concern, you may wash your duvet in hot water, but this should not be done too frequently.
• Run an extra rinse and spin cycle to get rid of excess water.
• Press out extra water using a towel, do not wring or twist your duvet.
  
• Down duvets should be dried in a dryer that is large enough to accommodate your duvet.
• Use a delicate cycle on low or medium heat. Drying can take several hours.
• Be sure to dry your duvet completely before use.
