Can You Put Throw Pillows In The Washing Machine?

You probably toss your bed pillows in the wash every few months, but throw pillows seem different. They sit on couches and chairs, collect dust and pet hair, and somehow feel too fragile for the machine. The fear of a lumpy, misshapen pillow after one cycle keeps many people reaching for a lint roller instead of the laundry basket.

The reality is simpler than the worry. Most modern throw pillows are built with machine-washable fillings like polyester or synthetic down, and a gentle cycle with cold water can freshen them up just fine. The trick is knowing which pillows are safe and which require a more careful approach — and that starts with a small habit you might be skipping.

Why Throwing a Pillow in the Wash Feels Risky

That hesitation you feel isn’t unreasonable. A washing machine can turn a once-fluffy pillow into a clumpy mess if the filling isn’t suited for it. Feather and down pillows, for example, need special handling to avoid clumping, and foam inserts can disintegrate in the drum.

But the bigger reason people hesitate is that throw pillows often have decorative covers, sequins, tassels, or delicate fabrics. Those trims don’t survive a standard cycle well. You’re not wrong to be cautious — you just need to separate the pillows by how they’re constructed before deciding on the cleaning method.

Which Fillings Can Take a Machine Wash?

Polyester fiberfill is the most common filling in throw pillows, and it’s the easiest to clean. According to The Spruce, polyester pillows are affordable, hypoallergenic, and can be washed once or twice a year without losing their shape. Synthetic down (microfiber) behaves the same way — it’s resilient and machine-safe.

Cotton-filled pillows also handle the machine well, though they absorb more water and take longer to dry. Pillows labeled “machine-washable” are usually safe regardless of the shell fabric, but you should still check the care label to confirm the temperature and cycle recommendations.

For pillows with removable covers, Southern Living recommends washing the cover separately from the inner form. That way you can use a stronger cycle on the cover without risking the filling.

Step-by-Step: Machine Washing Your Throw Pillows

Once you’ve confirmed the pillow is machine-safe, follow these steps to keep it in good shape. Use a gentle cycle with cold water and a mild detergent — the same kind you’d use for delicates or down alternatives. Wash similar colors together to avoid dye transfer, and never overload the machine; pillows need room to agitate.

1. Check the label and remove trims if possible. Tuck in any loose threads or remove detachable decorations that could snag.
2. Wash two pillows at once. This balances the load and prevents the machine from wobbling.
3. Add an extra rinse cycle. Leftover detergent can cause stiffness and attract dirt faster.
4. Dry on low heat with dryer balls. Tumble dry on low, adding wool dryer balls or clean tennis balls to break up clumps of filling.
5. Check for dampness before storing. Pillows can trap moisture in the core — dry an extra 15 minutes if you feel any coolness.

Polyester pillows are usually the easiest type to wash at home because the fill is more resilient than down or feather, according to Careonova. They bounce back with minimal effort.

When to Hand-Wash or Spot Clean Instead

Not every throw pillow belongs in the machine. Decorative pillows with beaded trim, sequins, embroidery, or metallic threads can get ruined by the agitation and tumbling. Same goes for pillows with foam inserts — those should never see the inside of a washer.

For those pillows, Peacock Alley’s care guide suggests hand-wash decorative pillows in a tub of cool water with a small amount of mild detergent. Gently squeeze the suds through the fabric, rinse thoroughly, and press out water without wringing. Reshape the pillow while damp and air-dry flat.

For light soiling on a pillow that can’t be fully washed, spot-cleaning with a damp cloth and a drop of dish soap works well. Test an inconspicuous area first to make sure the fabric doesn’t react.

How Often Should You Wash Throw Pillows?

Throw pillows don’t need the same frequency as bed pillows, but they still collect dust, allergens, and body oils from daily use. A good rule of thumb is to wash machine-safe throw pillows once or twice a year, or more often if they’re heavily used or in a pet-friendly home.

Between washes, fluff them in the dryer on a no-heat cycle with a dryer sheet to reduce dust. Vacuuming the surface with an upholstery attachment is another quick way to extend the time between deep cleans.

If the pillow starts looking flat or smells musty, that’s your sign to wash it sooner. Perspiration, spilled drinks, and pet dander all break down the filling over time, and a fresh wash restores both fluff and freshness.

The Bottom Line

Washing throw pillows in the machine is safe for most polyester, synthetic down, and cotton-filled pillows. Always start by reading the care label, then use a gentle cycle with cold water and mild detergent. For pillows with foam, delicate fabrics, or heavy decorations, hand-washing or spot-cleaning is the better choice to avoid damage.

If you’re unsure about a specific pillow’s filling or fabric, a certified home textile specialist or your local dry cleaner can give you a tailored recommendation based on the exact construction — no need to guess when a quick label check or a phone call settles it.
