Recommended Cleaning: The only recommended method of cleaning a featherbed is to take it to a professional launderer or dry cleaner. Feather and down products can be washed, but there are a few things to consider:
1. Featherbeds must be washed by a professional. They are simply too large to wash without commercial sized equipment.
2. It is critical that no harsh detergents be used and that the heat of drying not be too high. Harsh detergents and excessive heat will cause the feather and down to become dry and brittle and will result in breaking.
3. It is of the utmost importance to make absolutely sure that the feathers are totally dry. If they are not, they will become moldy and decompose. Drying a featherbed takes several hours. It may not be dry just because the fabric is dry. You must feel it carefully and make sure all of the feathers and down are dry and fluffy and that there are absolutely no clumps left.
4. The fabrics are 100% cotton. Just like a cotton shirt, they will shrink a little when washed.
This care will help your featherbed stay fresh and last a long time.
