How to Wash a Down or Synthetic Comforter at Home

Comforters are the silent workhorses of the bedroom, collecting dust, oils, and allergens long before you notice them. While many people default to expensive dry cleaning, most modern comforters are perfectly safe to wash at home provided you have access to a machine large enough to handle the bulk without crushing the fill. Doing it yourself ensures a deeper clean and saves you a trip to the cleaners. Success in this project hinges on two things: balance and patience. If you overload your machine, the comforter won't get clean; if you rush the drying process, you risk mold or mildew growth inside the batting. When done right, your comforter will emerge refreshed, loftier, and free of the stale scents that accumulate over time.

  1. Catch Tears Before Washing. Check every inch of the fabric for small tears or loose seams; if you find any, stitch them closed before washing to prevent the stuffing from leaking out. Use a stain remover pen or a dab of liquid detergent directly on any visible spots like makeup or food spills.
  2. Balance the Load Right. Use a large-capacity commercial-style washer, ideally one without a center agitator which can tear the fabric. Place the comforter in the drum in a loose, circular ring to keep the machine balanced during the spin cycle.
  3. Go Light on Detergent. Set the water temperature to cold or warm, never hot, and choose a delicate or permanent press cycle. Add only a small amount of liquid, mild detergent—about half of what you would use for a full load of towels—to avoid leaving soapy residue in the thick fill.
  4. Move Fast to Prevent Mildew. Move the wet comforter to the dryer immediately to prevent mildew. If the comforter is heavy, squeeze out as much excess water as possible while it is still in the washer before attempting to lift it into the dryer.
  5. Shake and Fluff Every 30 Minutes. Tumble dry on the lowest heat setting available to protect the fill, especially if it is synthetic or natural down. Add three clean wool dryer balls to help fluff the comforter and break up clumping as it dries.
  6. Air Out for Complete Dryness. Even if the comforter feels dry, it may still hold moisture in the center. Hang it over a sturdy rack or a clean railing in a sunny, ventilated room for at least four hours to ensure total dryness.
