Feather and down duvets add luxury and softness to a good night's sleep. The fluffy goose down provides superior warmth and comfort, but needs special care to ensure it will last a long time. Feather duvets don't require frequent washings; twice a year should do the trick. Make sure the comforter is machine washable, and use a large washing machine to allow maximum space. Laundromats usually offer large capacity washing machines if you don't have one at home. Use a mild washing powder for delicates to prevent excess wear on the down.
Fill the washing machine with cold or warm water and add the feather duvet. Choose the shortest or delicate wash cycle.
Measure the proper amount of mild washing powder according to the instructions on the package. Add it to the washing machine or detergent dispenser.
Check the duvet for soap residue when the cycle completes. If it needs another rinse, turn the rinse cycle on and wait for it to finish. If there is no rinse cycle, run the washing machine again on the shortest cold water setting without detergent and wait for it to finish.
Remove the feather duvet from the washing machine and hang it outside to air dry. Alternatively, place it in a large capacity dryer on low heat. Place a tennis ball in the dryer with the duvet to fluff up and even out the feathers. It can take up to three hours for a large comforter to dry in a dryer. Make sure the duvet is completely dry before using it.
