How to Wash Pregnancy Pillow Cover

That cover has been against your face, wedged under your belly, and shoved behind your back for weeks. It's picked up sweat, drool, and whatever that mystery spot on the couch was. Tonight's the night.

So here's how to wash a pregnancy pillow cover without wrecking it. Short version, in case you're reading this with one hand: check the tag, wash the cover on cold-to-warm, dry it low or air dry it. Not hot. Never hot. Everything below is just the detail around those three things.

Check the care label before anything goes in the machine

Unzip the cover and look inside. The tag is usually sewn into a seam near the zipper or down at the foot end.

That little tag is the boss here. Not a blog post, not a forum thread. The tag was written for the exact fabric and stitching in your hands, and it knows things a general guide doesn't.

One real slipcover label spells it out pretty clearly: machine wash separately on delicate at 30°C (that's 85°F), tumble dry low on delicate, cool iron if you feel like it. Some versions of that label also say "bleach as needed" — ignore that bit. You sleep pressed against this thing. If it needs stain treatment, reach for an oxygen-based cleaner instead of chlorine bleach. Bleach is harsh on fabric and harsh on skin.

If the tag is gone, faded, or printed in tiny symbols you can't decode at 11pm, go with the safe default: delicate cycle, cold to warm water, mild detergent, low heat to dry.

Cover vs. insert: which part you're actually washing

This is where most advice goes sideways. People talk about "washing a pregnancy pillow" like it's one object. It's two.

The cover is the fabric shell that zips off. That's the part soaking up sweat, oil, and stains, and it's the part you'll wash almost every time. Most pregnancy pillows come with a removable cover that's built for a machine.

The insert is the actual pillow — the stuffing and the lining around it. It doesn't need washing nearly as often, and with a big U-shaped pillow you might never machine wash it at all.

So pull the cover off and leave the insert alone unless it's genuinely grubby. Less to dry, less to ruin.

Machine washing the cover, step by step

• Unzip and remove the cover. Set the insert somewhere clean.
• Zip the cover back up. An open zipper is a snag waiting to happen.
• Shake it out so it's not going in as a ball.
• Wash it separately, or with other soft, light things at most. Covers are big and they wrap around everything else in the drum.
• Use delicate or gentle cycle with mild detergent — normal amount or a little less. Skip fabric softener. It coats the fibers and leaves a film that makes fabric feel less soft over time.
• Choose cold to warm water. More on this in a second, because it's the thing everyone argues about.

If the cover is huge, or you're washing the whole pillow rather than just the cover, you want a large front-loading machine. A top-loader with an agitator is rougher on bulky items and can stretch seams. People do get a whole pregnancy pillow through a machine wash and live to tell the tale. The catch is always the drying.

What water temperature to use (and why the advice online disagrees)

Here's the mess. One guide says cold or hot is fine. Another flat-out calls hot water "the enemy." A manufacturer's care label says 30°C, which is 85°F — barely warm at all.

They're all half-right, and you don't have to pick a side. Use this instead:

1. If the tag gives a temperature, that wins. Full stop. Usually it'll be 30°C / 85°F or a cold setting.
2. No tag? Cold to warm. Cold is the safest. Warm is fine if the cover is genuinely grubby and you want a bit more cleaning power.
3. Hot is what shrinks covers. Hot water causes the shrinking, the fading, and that stiff, pilled, scratchy feel. It's not worth it. Covers don't need it.

Worried warm water won't get it clean? Warm water plus detergent plus proper drying handles everyday sweat and dirt just fine. You're washing a pillow, not sterilizing surgical tools.

Hand-washing a cover when the label says no machine

Some covers, especially on older or fancier pillows, say hand wash only. Ignore that and you risk a shrunken cover that won't zip back on.

Fill a tub or big sink with cold or lukewarm water and a small amount of hand-wash-safe detergent. Push the cover under until it's soaked through. Then work it — squeeze, knead, massage the fabric for a few minutes, paying extra attention to the head end and any darker patches.

Same idea if you're working out how to wash a body pillow cover: cold or lukewarm water, a small amount of hand-wash-safe detergent, submerge it, massage it, done. Rinse with cool water until it runs clear. Don't wring it. Press the water out, roll it in a towel, press again.

For a giant 9ft U-shaped pillow, some people skip the sink entirely and use a tub of warm water with 2 tablespoons of dish soap and 2 tablespoons of baking soda. Soak, massage, rinse well. It works, but be ready for a heavy, dripping job — do this in a bathtub, not a bathroom sink.

How to dry a pregnancy pillow cover without shrinking or pilling

This is the part nobody explains properly. Everyone just says "it takes forever." True. Here's the plan anyway.

Air drying is safest. Hang the cover over a shower rod, a drying rack, or the back of a chair in a room with moving air. A fan pointed at it cuts the time a lot. Flip it once or twice.

If you tumble dry, go low. Low heat, delicate setting, and pull it out while it's still slightly damp. Lay it flat to finish. Covers that come out of a hot dryer are the ones that pill, shrink, and take on that sad crunchy texture.

Don't hang a heavy wet cover by one corner. The weight stretches it out of shape. Lay it flat or drape it over something broad.

Expect it to take far longer than a T-shirt. Overnight is normal.

How to refresh a cover without washing it

Not every situation calls for a full wash. Between washes, or when the cover just smells a bit lived-in:

• Spot clean. A little mild detergent or oxygen-based cleaner on a damp cloth, dabbed on — not scrubbed. Work from the outside of the stain inward so you don't spread it.
• Vacuum it. A pass with an upholstery attachment lifts dust, crumbs, and pet hair.
• Air it out. Hang the cover somewhere breezy for an hour. Fresh air does more than you'd think.
• Baking soda shake. Sprinkle it on, wait 15 minutes, vacuum it off.
• Rotate your pillows. Own more than one and you'll wash each of them less often.

Momcozy, PharMeDoc and 9ft U-shaped pillows: brand and shape notes

Brands rarely publish one universal care rule covering every model they've ever made, and covers change between versions. So don't trust a chart online. Trust the tag inside your specific cover.

That said, the pattern is steady across these brands and shapes:

• Momcozy and PharMeDoc pillows both follow the standard setup — a removable cover over a separate insert. Machine washing the cover is normal.
• No tag? Delicate cycle, cold to warm, mild detergent, low dry.
• 9ft U-shaped pillows are the hard ones. The cover is enormous, heavy when wet, and awkward in a home machine. Hand washing in a tub, or a large front-loader, is the realistic path.

How often to wash it, and what to do when the cover is looking yellow

Every one to two weeks if you're using it nightly. It's against your skin and you're sweating in it. Wash sooner if you've been sick, if you've been sweating a lot, or if it just smells off.

Now the yellow. If your cover is going yellow, that's usually built-up body oil and sweat. It happens to all bedding, not just pregnancy pillows. Cold-to-warm water, mild detergent, and an oxygen-based stain treatment before the wash does the most good. Hot water and chlorine bleach can set yellow in rather than lifting it out.

And yes, this works on a partner's pillow too. Same routine, same rules.

A few quick questions that come up

Can you wash a pregnancy pillow in the washing machine? Yes — most have a removable cover built for machine washing, and that's the part you'll wash most. Washing the entire pillow calls for a large front-loading machine and a long drying time, so read the tag first.

How far into pregnancy should you use a pregnancy pillow? There's no cleaning answer here — it's about comfort, and it varies by person. Whenever you start, the washing routine stays the same.

Can you wash a Momcozy pregnancy pillow cover? Check the tag inside the cover for the cycle and temperature. No tag? Delicate cycle, cold to warm, mild detergent.

Once you've got the cold-wash, low-dry routine down, it carries over to everything else soft in your house. For the next washable things on your list — sock shoes, booties, and baby socks — the Baby Sock Shoe cleaning and care guides walk you through it the exact same way.
