How to Wash a Down Comforter at Home or at the Laundromat
Most down comforters can be washed at home if the machine is big enough. The hard part is drying: low heat, dryer balls and patience.
Most down comforters can be washed if the care label allows it: use a large-capacity front loader or a top loader without a center agitator, a gentle or bulky cycle, a small amount of mild or down-specific detergent, and an extra rinse. Then dry it on low heat with wool dryer balls or clean tennis balls, which can take several hours, until the down is completely dry inside. If your machine is too small for the comforter to move freely, use a commercial washer and dryer at a laundromat.
Down holds a lot of water and detergent, which is why rinsing and drying are where most problems happen. Done carefully, washing brings back loft and removes body oils that make down clump and smell over time.
Check the care label first
The label decides. Some down comforters are machine washable, some say dry clean only, and some say professional cleaning only because of the fabric shell or construction. If the label says dry clean only, take it to a cleaner that handles down. Our guide to laundry care symbols explains the icons, and the US Federal Trade Commission’s care labeling guidance notes that a “dry clean only” label means the maker has evidence the item cannot be safely washed.
Before washing, look for tears or weak seams and stitch them closed. A small hole can leak a lot of down in a wash cycle.
Will it fit in my washer?
The comforter needs room to move and get fully wet. Stuffed tight, it will not rinse properly and the seams strain. As a rough guide:
| Machine | Suitable? | Notes |
|---|---|---|
| Large-capacity front loader | Usually yes for twin to queen | Gentle on baffles; check it is not packed tight |
| Top loader without agitator (impeller) | Often yes | Push the comforter down so it is fully submerged |
| Top loader with center agitator | Not ideal | Agitators can twist and tear the shell and internal baffles |
| Compact or standard front loader | Often too small for queen or king | Use a laundromat machine |
| Laundromat commercial washer | Yes, including king size | Wipe the drum first; use your own detergent |
If in doubt, a laundromat wash and dry is usually far cheaper than replacing a comforter damaged in a machine that is too small.
What you need
- Mild liquid detergent or a detergent made for down
- Three or four wool dryer balls or clean tennis balls
- Needle and thread for small repairs
- A large washer and dryer (home or laundromat)
- A few hours for drying
Step-by-step: washing a down comforter
- Remove the duvet cover and wash it separately.
- Spot-treat stains by gently working a little detergent into the shell fabric, pushing the down away from the stain first if you can.
- Load the comforter alone, spreading it loosely around the drum.
- Use a small amount of mild or down detergent. Low-sudsing products rinse out more easily. Skip fabric softener and chlorine bleach, which coat or damage down.
- Choose a gentle, delicate or bulky cycle with cool or warm water as the label allows.
- Add an extra rinse, or run a second rinse and spin cycle, so no detergent stays in the down.
- Run an extra spin if your machine allows, to remove more water before drying.
Step-by-step: drying it properly
- Transfer to a large dryer with the dryer balls or tennis balls. They knock the down clumps apart as it dries.
- Use low heat. High heat can scorch the shell and damage the down. Low heat takes longer but is safer.
- Stop every 30 to 45 minutes, pull the comforter out, shake it, and break up any clumps by hand.
- Keep going until it is completely dry. This can take several hours. Feel the center and the corners; any damp, clumped spot means it needs more time.
- Air it out for a few hours afterward before putting it on the bed or storing it.
A comforter that is put away even slightly damp can develop a musty smell and mildew. If it smells “wet dog” after drying, that usually means the down is still damp inside; dry it longer.
Clumps after washing
Clumps are almost always wet down. Keep drying on low with the balls and shake it out by hand. If clumps remain once it is fully dry, there may be leftover detergent; a rinse-only cycle and another full dry often fixes it.
How often to wash a down comforter
With a duvet cover, washing the comforter a few times a year, or only when it is soiled, is generally enough. Washing too often wears the shell and down. Wash the cover on your regular schedule; see how often to wash sheets and bedding. For pillows filled with down, the method is similar; see how to wash a pillow.
Use detergent as the label directs, store it out of reach of children and pets, and if someone swallows, inhales or gets a cleaning product in the eyes, call Poison Control at 1-800-222-1222 (US) or emergency services.
Bottom line
Follow the care label, wash the comforter alone in a large machine without an agitator, use a little mild detergent and rinse twice. Then dry it on low with dryer balls for as long as it takes to dry completely. When your machine is too small, the laundromat is the cheap, safe option.
FAQ
Can I use regular detergent on a down comforter?
A small amount of a mild liquid detergent usually works. Avoid heavy doses, fabric softener and chlorine bleach. Down-specific cleaners are an option, not a requirement, unless the label says so.
How long does a down comforter take to dry?
Several hours on low heat is common, depending on size and the dryer. Check that the center is completely dry before you stop.
Can I air dry a down comforter?
It can take a very long time and the down may clump or smell musty. A dryer on low heat is usually more reliable.
Should I dry clean a down comforter?
Only if the care label calls for it. Many are made to be washed in water.
