Because of the size, the hassle, and the simple fact that comforters don’t look dirty the way sheets or pillowcases do, most of us go way too long between cleanings. But the moment you start to notice that musty smell, the extra weight, or a general dinginess no fluffing can fix, they're clear signs your comforter is overdue for a wash.
So, when is the right time to wash it? Too often, and you risk breaking down the filling. Not often enough, and you end up sleeping under a cloud of dust, dander, and buildup. In this post, we guide you through the ideal cleaning schedule so you’re not overwashing or under-washing. Let’s get into it!
If you have allergies or asthma, your comforter might be making things worse without you even realizing it. Dust mites, pollen, and pet dander build up in bedding over time, especially in thick, warm comforters that don’t get cleaned often.
Even if you wash your sheets weekly, your comforter can still collect irritants that affect your breathing. That’s why it’s important to wash your comforter every 2 to 3 months, minimum.
If you want a healthier night’s sleep with fewer allergic reactions or breathing issues, here are some key things to keep in mind:
Stick to washing your comforter every 2 to 3 months using a large-capacity washing machine with mild, fragrance-free detergent. Always double rinse to remove any leftover soap residue.
If your comforter is machine-washable and made from cotton or polyester, washing it with hot water (at least 130°F) can help kill dust mites. Check the care label first; some textiles, like wool or silk, can't handle heat.
Dry the comforter thoroughly using a low-heat setting and toss in a couple of wool dryer balls or clean tennis balls to maintain loft. Never put a slightly damp comforter back on the bed; it can grow mold or mildew inside the fibers.
Add a removable duvet cover that's easy to wash weekly. This acts as a protective barrier and catches allergens before they reach your comforter.
Sleeping with pets brings comfort, but it also introduces hair, dander, dirt, and sometimes even fleas into your bedding. Comforters are thick and absorbent, so they trap pet debris easily, especially if your pet loves to burrow or sleep right on top of it.
Even if you vacuum or shake it out regularly, that’s not enough to fully clean it. To stay on top of hygiene, wash your comforter every 2 to 3 months.
Before washing, shake the comforter outside to remove loose fur. Use a lint roller or vacuum if needed. Spot clean any pet stains using a solution of vinegar and water or an enzyme-based stain remover.
Use a detergent that’s free from dyes and perfumes to avoid irritating your pet’s skin. Pet-safe laundry soaps also help break down oils and odors more effectively.
Pet hair can cling to fabric even after washing. Run an extra rinse cycle to remove residue and help flush away leftover dander and soap.
Dry thoroughly on low to medium heat with wool dryer balls or clean tennis balls to fluff the fabric and reduce matting. This helps preserve the structure and feel of the comforter.
If you tend to sweat while you sleep, or live in a hot, humid climate, your comforter collects more body oils and moisture than average. Over time, this leads to stains, odors, and even hidden mildew deep inside the filling.
Even if you don’t see visible marks, the sweat soaks into the fabric and weakens it. That’s why you should clean your comforter every season (every 3 to 4 months) to keep it fresh and safe to sleep under.
Pair your comforter with breathable cotton or linen sheets and covers. These materials help wick moisture away from your body and reduce how much sweat seeps into your comforter.
If you notice yellowing or sweat stains around the edges, pretreat them before they set. Use a mixture of water, mild laundry detergent, and a bit of vinegar to lift the stain before a full wash.
When washing, consider adding a half-cup of white vinegar or baking soda along with your detergent to eliminate sweat smells. Avoid using fabric softener; it can coat fibers and lock in odors.
In humid areas, it’s critical to make sure your comforter is fully dry before storing or using it again. Use low heat and allow for a longer drying time. Check for damp spots before folding or remaking the bed.
Accidental spills happen. Whether it’s coffee in the morning or snacks during a movie night, your comforter is bound to pick up stains, crumbs, and sticky residue if you regularly eat in bed. Even if you’re careful, food and drink can soak into the fabric and attract bacteria or bugs.
That’s why you should wash your comforter every 3 months if food or drinks are part of your bedtime routine.
Blot liquid spills immediately with a clean towel to prevent deep soaking. Avoid rubbing, which can spread the stain. Treat the area with diluted dish soap or a laundry stain remover.
Shake the comforter outside every week or two. Use a handheld vacuum or lint roller to collect crumbs stuck in the seams or stitching.
Even if your comforter looks clean, stick to a three-month schedule for full washing. If you spill something greasy or sugary, don’t wait; wash it right away to avoid permanent stains or bad smells.
Use a washable duvet cover that you can strip off and clean after any spills. This reduces how often the inner comforter needs to be washed.
Using a top sheet and a duvet cover offers solid protection for your comforter. These layers catch the bulk of sweat, skin cells, and oils, so your comforter stays cleaner longer. As long as you wash the cover and sheets weekly, your comforter doesn’t need to be cleaned as frequently. Washing every 6 months is usually enough to keep it in good shape.
Always wash your duvet cover and top sheet at least once a week. These layers take the brunt of daily use and keep your comforter shielded from moisture, lint, and body oils.
Every month or so, flip or rotate your comforter to prevent uneven wear. This also helps you spot any early signs of staining or buildup that may require a quicker wash.
Even with a top sheet and cover, check the comforter thoroughly at the start of each season. If it smells musty, has visible stains, or feels flat, wash it even if you’re not at the 6-month mark yet.
On dry days, hang your comforter outside for a few hours. Sunlight helps disinfect, lift odors, and fluff the filling without a full wash.
There’s something about waking up under a freshly cleaned comforter that just makes the day feel better, lighter, calmer, and healthier. If your comforter hasn’t had a deep clean in months (or maybe ever), now’s the perfect time to give it a deep cleaning.
