Quick Answer
Whether a duvet can be washed depends on its filling, construction, size, and care label. Many duvet covers are machine washable, but duvet inserts may need a large-capacity washer or professional cleaning. Check the label before washing.
How to Wash Duvet
Check the care label first; instructions vary for down, feather, wool, synthetic, and other fillings. Wash only if permitted and if the duvet fits loosely in the machine. Use a large-capacity washer, a mild detergent, and the cycle specified on the label. Avoid overloading or forcing a bulky duvet into a small washer. If the label says dry clean only, or the duvet is too large to wash safely, use a professional cleaner. Duvet covers can usually be washed separately according to their own care labels.
How to Dry Duvet
Follow the care label. If machine drying is allowed, use the specified heat setting and make sure the duvet dries completely; bulky fillings may need a large dryer and periodic redistribution. Some fillings and constructions require air drying or professional drying. Do not store a damp duvet, as trapped moisture can cause odors or mildew.
What to Avoid
Do not assume every duvet is machine washable. Avoid washing it in an undersized machine, using excessive detergent or bleach, or using high heat unless the label permits it. Do not fold or store it while damp.
Important Warnings
Care requirements vary by filling, fabric, stitching, and construction, so the care label and manufacturer instructions take priority. Washing or drying a duvet incorrectly can cause shrinkage, clumping, damage to the filling, or a lingering damp interior.
