DOWN PRODUCTS CARE
Generally, down comforters and pillows should be shaken out daily to restore their loft. With fixed construction comforters (i.e., baffle box and sewn-through boxes), the down will not move from outside its respective box during the shaking. When stripping the sheets off the bed, the consumer also may wish to fluff out the featherbed to give its loft back. Consumers can also tumble dry their down products to get some extra loft.
It is a great idea to protect a comforter, pillow, or feather bed with a fabric cover of some sort. Duvet covers for comforters, pillow protectors, and feather bed protectors are worthwhile investments that extend the life of down bedding significantly. Additionally, by using a duvet cover, the consumer is able to change the look of their bed, simply by changing the cover but keeping the same comforter.
Most consumers choose to have their down bedding professionally dry cleaned. However most fabrics allow gentle machine washing, if the washer is large enough to accommodate the product. A small amount of mild dish detergent is a good way to clean the bedding (avoid using laundry detergent as it leaves a phosphate coating on the down clusters and reduces the ability for the down to regain its loft).
Moths usually do not attack the down or feather filling-only the shells are susceptible (As all linens are).
Down and feathers have no preset time for spoilage-well treated they can last dozens of years.
