Throw pillows collect dust, skin oils, pet hair, crumbs, and everyday odors, but the safest way to clean them depends on two things: the cover fabric and the insert filling. Before washing anything, unzip the cover if it is removable and check the care tag on both pieces. Cotton and polyester covers are often machine washable, while silk, wool, velvet, leather, suede, beaded, or embroidered pillows usually need gentler care.
Quick Answer
Most throw pillow covers can be cleaned every 1–2 months, while inserts usually need washing every 3–6 months unless they are stained, musty, used daily, or exposed to pets. Always remove the cover first, follow both care tags, pretreat stains, use gentle washing, and dry everything completely.
Key Takeaways
- Wash removable covers more often than inserts because covers touch hands, pets, food, and furniture surfaces.
- Use the gentlest method that will clean the pillow: vacuum, spot clean, hand wash, machine wash, or dry clean based on the label.
- Foam, latex, leather, suede, heavy embellishments, and many velvet or silk pillows should not go in the washing machine unless the care tag clearly says they can.
- Never store or reuse a damp insert. Thick pillows can feel dry outside while moisture remains inside, which can lead to odor or mildew.
At a Glance
| Time Required | 15–30 minutes active cleaning time; several hours for thick inserts to dry fully |
| Difficulty | Easy for cotton/polyester covers; moderate for down, feather, delicate fabrics, or non-removable pillows |
| Tools Needed | Vacuum with upholstery attachment, mild detergent, white cloths, mesh laundry bag, towel, drying rack, clean dryer balls if tumble drying is allowed |
| Cost | Usually $0–$10 at home; more if professional dry cleaning is needed |
How Often Should You Clean Throw Pillow Inserts?
Clean throw pillow covers every 1–2 months in normal use, or every 1–2 weeks if pets sleep on them, someone has allergies, or the pillows sit in a high-traffic area. Clean throw pillow inserts every 3–6 months if they are used often, and sooner if they smell musty, look stained, feel flat, or trigger sneezing. Decorative pillows that are rarely touched may only need regular vacuuming and an occasional deeper clean.
The care tag always wins. If the label says “spot clean only” or “dry clean only,” do not treat the pillow like a regular washable cotton cover. The American Cleaning Institute recommends sorting laundry by fabric care instructions, treating stains before washing, and choosing washer and dryer settings that match the textile.
Note: Cleaning can reduce dust, dander, and debris on pillows, but it is not a medical treatment for allergies or asthma. If dust mites are a concern, choose washable covers and inserts when possible and follow your clinician’s advice.
Essential Considerations for Cleaning Different Pillow Cover Fabrics
The fabric determines how aggressive you can be. Smooth cotton can usually handle more water and agitation than velvet, silk, wool, suede, or embellished fabric. Always test any stain remover or detergent on a hidden seam first to check for color bleeding, texture change, or water rings.
Fabric-Specific Cleaning Methods
| Fabric Type | Best Cleaning Method | How Often |
|---|---|---|
| Cotton | Machine wash on gentle with mild detergent if the label allows; air dry or tumble dry low. | Every 1–2 months, or sooner for stains and pets. |
| Polyester or microfiber | Machine wash gentle or hand wash; use cold or warm water based on the label. | Every 1–2 months for covers used often. |
| Linen | Use a delicate cycle or hand wash; air dry to reduce shrinkage and wrinkles. | Every 1–2 months, depending on use. |
| Velvet | Vacuum with an upholstery attachment and spot clean carefully; dry clean if the label requires it. | Vacuum weekly; deep clean only as needed. |
| Silk or wool | Hand wash only if the care tag allows; otherwise use professional dry cleaning. | Spot clean promptly; deep clean sparingly. |
| Faux fur | Hand wash or use a gentle machine cycle if allowed; air dry and brush lightly when dry. | Monthly for heavy use; otherwise as needed. |
| Leather, suede, beaded, sequined, or embroidered covers | Do not machine wash. Vacuum gently, spot clean with a fabric-appropriate cleaner, or use a professional cleaner. | Spot clean only when needed. |
Recommended Detergents for Fabrics
Use a mild liquid detergent for most washable cotton, linen, polyester, and microfiber covers. For wool or silk, use a detergent made for delicate protein fibers only if the care tag allows hand washing. Avoid chlorine bleach on delicate fabrics, wool, silk, leather, suede, dark colors, and anything with embroidery or trim. Oxygen bleach may be safer for some washable fabrics, but it still needs a hidden spot test and label check first.
Warning: Do not machine wash pillows labeled “dry clean only,” foam inserts, leather, suede, silk velvet, heavy beadwork, sequins, or pillows with loose seams. Water, agitation, and heat can shrink fabric, ruin texture, loosen trim, or break the insert apart.
Step-by-Step Instructions for Washing Throw Pillow Covers
- Remove the insert. Unzip or unbutton the cover and set the insert aside. Never wash a removable cover with the insert still inside unless the label specifically says to wash the whole pillow.
- Check the care tag. Look for water temperature, wash cycle, bleach instructions, and drying symbols. If there is no label, choose the gentlest safe method: vacuum and spot clean first.
- Shake and vacuum. Remove loose crumbs, dust, pet hair, and lint before adding water.
- Pretreat stains. Blot fresh stains with a white cloth. Apply a small amount of mild detergent or stain remover to a hidden area first, then treat the stain if the fabric passes the test.
- Use a mesh laundry bag. This protects zippers, tassels, and seams on machine-washable covers.
- Wash gently. Choose a gentle or delicate cycle with cold or warm water according to the label. Use only the recommended amount of detergent, because residue can make pillows feel stiff or attract soil.
- Inspect before drying. If the stain remains, repeat the stain treatment before drying. Heat can set stains permanently.
- Dry carefully. Air dry delicate covers flat or on a rack. If tumble drying is allowed, use low heat and remove the cover promptly to reduce wrinkles.
The American Cleaning Institute’s stain guide recommends treating stains as early as possible, laundering according to fabric care instructions, and avoiding the dryer until the stain is removed.
How to Wash Throw Pillows Without Removable Covers
Throw pillows without removable covers need extra caution because the outer fabric and inner filling must survive the same cleaning method. Start with the least amount of moisture possible.
- Vacuum both sides. Use an upholstery attachment to remove dust, hair, and crumbs from seams and corners.
- Spot test. Dab a hidden area with a small amount of diluted mild detergent. Wait until dry and check for dye transfer, texture change, or water rings.
- Spot clean stains. Blot, do not rub. Work from the outside of the stain toward the center so it does not spread.
- Hand wash if safe. If the label allows water cleaning, press the pillow gently in a basin of cool or warm water with a small amount of mild detergent. Do not twist or wring.
- Rinse well. Detergent left inside the pillow can cause stiffness and attract dirt.
- Press out water with towels. Roll the pillow in clean towels and press firmly. Avoid twisting, which can distort the filling.
- Dry completely. Air dry flat with good airflow, flipping often. If the label allows tumble drying, use low heat or air fluff and check frequently.
Pro Tip: For machine-washable inserts, wash two similar-size pillows together to balance the washer. If tumble drying is allowed, add clean dryer balls to help separate the filling and reduce clumping.
Best Methods for Cleaning Different Types of Pillow Inserts
The insert fill is just as important as the cover fabric. A washable cotton cover does not automatically mean the insert can go in the washer.
Care for Natural Fillings
- Down and feather inserts: Many down or feather inserts can be washed if the label allows it, but they need gentle handling, a small amount of mild detergent, thorough rinsing, and complete drying on low or no heat. If the cover fabric is delicate or the tag says dry clean only, use a professional cleaner.
- Wool inserts: Wool can felt, shrink, or lose shape with agitation and heat. Spot clean or use professional cleaning unless the care tag gives washable instructions.
- Cotton inserts: Some cotton inserts are washable, but they can shrink or dry slowly. Use gentle washing, avoid high heat, and make sure the center is fully dry before putting the cover back on.
Maintain Synthetic Materials
Polyester and down-alternative inserts are often the easiest to wash. Use a gentle cycle, mild detergent, and low heat or air drying if the tag allows. Avoid overloading the washer, because packed pillows do not rinse well and can dry unevenly.
Foam, Latex, and Memory Foam Inserts
Solid foam, shredded foam, latex, and memory foam inserts usually should not be machine washed unless the label clearly says they can be. Washer agitation can tear foam and trap water deep inside. Vacuum them, spot clean the surface with a lightly damp cloth, blot with a dry towel, and air dry completely before replacing the cover.
Outdoor Throw Pillow Inserts
Outdoor pillows may resist moisture, but that does not make them maintenance-free. Brush off dirt, vacuum seams, and spot clean stains promptly. If the cover is removable, wash it separately according to the label. Let outdoor inserts dry in moving air before storing them so trapped moisture does not create musty odors.
Effective Stain Removal Techniques for Throw Pillows
Stains are easier to remove when you treat them quickly. Use white cloths so dye from the cloth does not transfer to the pillow, and avoid scrubbing delicate textures like velvet, silk, wool, or faux fur.
| Stain Type | What to Do |
|---|---|
| Food or drink | Lift solids with a spoon, blot liquid, rinse washable fabric from the back with cool water, then pretreat before washing. |
| Oil or grease | Blot first, apply a small amount of liquid detergent to washable fabric, wait a few minutes, then launder using the warmest water safe for the fabric. |
| Pet accidents | Blot thoroughly, use an enzyme cleaner only if it is safe for the fabric, then rinse or launder according to the label. |
| Blood or protein stains | Use cold water first. Do not start with hot water, because heat can set protein stains. |
| Mildew or musty odor | Wash only if the pillow is washable. Use the warmest safe setting, dry completely, and discard the insert if odor remains or the filling shows mold spots. |
Drying Your Throw Pillows: Tips for Optimal Results
Drying is where many throw pillows go wrong. A pillow can feel dry on the outside while the center is still damp. That trapped moisture can cause musty smells, mildew, or clumped filling.
- Press out extra water first. Roll wet pillows or inserts in clean towels and press. Do not wring.
- Use low heat only if allowed. High heat can shrink covers, damage synthetic fibers, and harm delicate fills.
- Fluff during drying. Pause the dryer every 30–45 minutes to shake and redistribute filling.
- Air dry delicate pieces. Lay covers or pillows flat on a rack in a well-ventilated area. Flip often.
- Check the center. Squeeze the thickest part of the pillow. If it feels cool, heavy, or damp, keep drying.
For dust-mite concerns, the Mayo Clinic recommends washing bedding weekly in water that is at least 130°F when the fabric can tolerate it, or using dryer heat above 130°F for at least 15 minutes before washing and drying to remove allergens. For throw pillows, apply that guidance only to washable covers and inserts that can safely handle those temperatures.
Maintaining Pillow Freshness: Tips for Longevity and Care
Regular light maintenance keeps throw pillows fresher between deeper cleanings and helps the fabric last longer.
- Vacuum weekly. Use an upholstery attachment to remove dust, pet hair, crumbs, and lint.
- Rotate pillows. Turn and rotate pillows so one side does not collect all the wear, sunlight, or body oils.
- Spot clean quickly. Treat spills before they soak into the insert.
- Use washable covers. Covers protect inserts and are easier to clean than whole pillows.
- Keep humidity under control. The American Lung Association notes that dust mites thrive in humid settings and recommends keeping home humidity below 50 percent.
- Store pillows clean and dry. Use breathable storage bags, not damp plastic bins, and never store a pillow that is even slightly wet.
The safest rule is simple: wash only what the care tag allows, use the gentlest effective method, and never put the pillow back on the sofa until the cover and insert are completely dry.
Troubleshooting Common Throw Pillow Cleaning Problems
The Insert Is Lumpy After Washing
Shake the insert by hand and break up clumps while it is still slightly damp. If tumble drying is allowed, dry on low or air fluff with clean dryer balls, stopping often to separate the filling.
The Pillow Still Smells Musty
Keep drying. If the pillow is fully dry and still smells musty, the odor may be trapped deep in the filling. Rewash only if the label allows it. If the smell remains or you see mold, replace the insert.
The Cover Shrank
Do not force the insert back in, because tight pressure can tear seams or warp the pillow shape. Air drying is safer for shrink-prone covers in the future.
The Colors Bled
Stop washing with other items. Wash bright, dark, or patterned covers separately, and test stain products on a hidden seam before treating visible areas.
Frequently Asked Questions
Are throw pillow inserts washable?
Some throw pillow inserts are washable, but it depends on the fill. Polyester and some down-alternative inserts are often machine washable on gentle. Down, feather, cotton, and wool need label-specific care. Foam, latex, and memory foam inserts usually should be vacuumed and spot cleaned instead of machine washed.
How do you wash throw pillows that do not have a removable cover?
Vacuum first, spot test a hidden area, then spot clean stains with a lightly damp white cloth and mild detergent. If the label says the whole pillow is washable, hand wash or machine wash gently as directed. Press out water with towels and dry the pillow completely before use.
Can you put throw pillows in the dryer?
Only put throw pillows in the dryer if the care tag allows tumble drying. Use low heat or air fluff for most washable inserts, and add clean dryer balls to help keep the filling loose. Delicate covers, wool, silk, foam, leather, suede, and embellished pillows should usually air dry.
How often should you wash decorative pillow covers?
Wash removable decorative pillow covers every 1–2 months in normal use. Wash them more often if pets use them, the pillows sit in a busy family room, someone eats near them, or allergies are a concern. Spot clean stains immediately between washes.
Can you wash velvet throw pillows?
Some washable velvet blends can be cleaned gently, but many velvet pillows should be vacuumed, spot cleaned, or dry cleaned. Water can crush the pile or leave marks, so always check the label and test a hidden area first.
What is the safest way to freshen throw pillows between washes?
Vacuum both sides, shake the pillow outside, spot clean small marks, and air it in a dry, well-ventilated area. Do not rely on fragrance sprays to cover odors; if a pillow smells musty, check for dampness and clean or replace the insert.
Conclusion
Clean throw pillows by matching the method to the material. Wash sturdy removable covers regularly, clean inserts less often but more carefully, and treat stains before they set. When in doubt, vacuum and spot clean first, then follow the care label. The final step matters most: dry covers and inserts completely before putting your pillows back on the sofa, bed, or chair.
