How to Clean a Pregnancy Pillow

How to Clean a Pregnancy Pillow

That pillow has been with you through the second trimester, the heartburn, the hip pain, and the night you cried because you couldn't get comfortable. It's also now a little bit gross. You know it. You've known it for weeks.

Here's the honest reason you've been putting it off: it's not the washing. It's the drying. A big U-shaped insert soaks up water like a sponge and then holds onto it for what feels like a week. That's the part that makes people give up and buy a new one instead.

So let's handle that first, then work out how to actually wash the thing. And before any of it, one rule that overrides everything below.

Read the care tag first: cover, insert, or both?

Find the tag. It's usually sewn into a seam on the cover, or tucked inside the zip. Read it before you do anything else, because the tag decides your path:

  • Tag says machine wash → follow it, and use the settings below.
  • Tag says hand wash only → tub or basin, no exceptions. Plenty of inserts are made this way, and a gentle cycle can still wreck a fill that isn't built for it.
  • Cover comes off → wash the cover normally. Deal with the insert separately, and less often.

Zip the cover off and look at both pieces. You may find the cover is a standard machine wash and the insert is hand wash only, which means you're doing two different jobs. That's normal, and it's the part most guides skip.

Machine washing a pregnancy pillow: cycle, temperature, and detergent

If your tag allows it and your washer is big enough to actually let the pillow move around, here's the setup:

  • Water: cold or warm. Cold is safer for the fill and the fabric.
  • Cycle: gentle or delicate.
  • Detergent: a mild one, and not much of it. A small amount goes a long way on a big pillow.
  • Extra spin: yes, if your machine offers it. The more water you get out now, the shorter the drying nightmare later.

Two things that matter more than people expect. First, don't cram it in alone — a giant pillow can throw your washer off balance, so add a couple of towels to even the load out. Second, if you can barely close the lid, your machine is too small. Forcing it means the pillow never gets properly rinsed, and soap left in the fill is what makes it smell weird three days later.

For cover-only loads, just wash the cover like you would sheets.

What to leave out of the wash (bleach, fabric softener, and why)

No bleach. It breaks down fibers over time, and on a pillow you're breathing next to for eight hours a night, that's not a trade you want.

No fabric softener. It leaves a coating on the fill. That coating traps oils and smells instead of letting them rinse away, so your pillow ends up holding onto odors longer, not shorter. Skip the dryer sheets for the same reason.

If you want a little scent, a drop of gentle detergent is enough. That's it.

Hand washing a 9ft U-shaped pillow in the tub: the dish soap and baking soda method

Hand washing a 9ft U-shaped pillow in the tub

This is the one people actually search for, because a 9-foot U-shaped pillow is roughly the size of a small adult and fits in almost no washing machine on earth.

Fill your bathtub with warm water. Add 2 tablespoons of dish soap and 2 tablespoons of baking soda. Swish it around with your hand until it's mixed and slightly foamy.

Then submerge the pillow. Really push it under — the middle of a U-shape loves to float. Let it soak for 15 to 30 minutes, then press and knead it with your hands, working from one end to the other. Don't wring or twist it; that's how fills get lumpy.

Drain the tub and refill with clean water to rinse. You'll probably need to do this twice. Squeeze water through the pillow, drain, repeat, until the water runs clear with no slippery feel. Any soap left behind will turn into a smell once it dries.

For a smaller pillow, a basin works the same way: cold or lukewarm water, a small amount of hand-wash-safe detergent, massage it in, then rinse thoroughly.

Heads up: a soaked 9ft pillow is heavy. Get help lifting it out, or you'll be doing it in stages while your back files a complaint.

How to clean a pregnancy pillow without washing it

Sometimes you don't need a full wash. You need the smell gone and the surface freshened, and you've got twenty minutes.

  • Vacuum it. A vacuum with an upholstery attachment pulls dust and crumbs out of the fabric.
  • Baking soda dry-clean. Sprinkle baking soda over the whole pillow, let it sit for 15 to 30 minutes, then vacuum it off. It lifts oils and dulls odors.
  • Wipe it down. A cloth dampened with warm water and a little mild soap handles small spots. Wipe, then wipe again with just water.
  • Air it outside. A couple of hours in fresh air and indirect sun does more than you'd think.
  • Wash just the cover. If the cover unzips, this is your best shortcut by far. The cover is the part touching your skin, your hair, and your night sweats. Clean that and you've solved most of the problem.

Drying: air dry vs. dryer, and why a big insert takes so long

This is the part nobody explains, and it's the reason your pillow is still sitting there unwashed.

A thick insert holds a huge amount of water deep in the middle. The outside can feel bone dry while the core is still damp, and that damp core is what grows mildew and that sour, musty smell.

Air drying is the safest option. Lay the pillow flat on a drying rack, or drape it over two chairs so air can move underneath. Flip it every few hours. Out of direct sun, since strong sun can fade the cover and stress the fill. Expect a full day at minimum, often two. Yes, really.

Tumble drying is faster but needs supervision:

  • Low heat only. Hot heat can clump or melt certain fills.
  • Add a couple of dry towels or dryer balls to help fluff it and speed things up.
  • Check it every 30 minutes. Pull it out, press your hand deep into the thickest part. If it feels at all cool or damp, back in it goes.
  • Expect several cycles. Not one. Several.

One thing to be careful about: don't crank the heat to hurry it along. A scorched or melted fill is a permanent problem, and you'll be buying a replacement anyway.

Washing the cover vs. the insert (and how often each really needs it)

The cover is the workhorse. It collects sweat, oils, skin cells, and drool. Wash it every one to two weeks if you're using the pillow nightly, and more often if you're running hot or leaking.

The insert is the low-maintenance one. It doesn't touch your skin directly, so every two to three months is plenty for most people, and spot cleaning in between is fine. Wash it sooner if it smells, if anything spilled on it, or if it's been sitting somewhere damp.

If your pillow doesn't have a removable cover, treat the whole thing as one piece and lean on the spot-clean and baking soda routine between full washes.

Momcozy, PharMeDoc, and other brands: why the tag beats generic advice

Every brand builds its pillows differently. Some use polyester fiberfill that handles a gentle machine cycle fine. Others use shredded memory foam, which generally should not go in a washing machine at all — water can break down the foam and turn the inside into a lumpy mess. Cover construction varies too.

So the internet's advice, including everything on this page, is a starting point. Your tag is the authority. If Momcozy's tag says hand wash, hand wash. If another brand's says machine wash cold on gentle, do that. When the tag is missing or unreadable, go with the gentlest option: hand wash, low heat, slow dry.

Keeping it fresh between washes: germs, smells, and sanitizing

You don't need to wash a pillow to keep it from getting gross.

Wash your sheets and pillowcase on your normal schedule so the pillow isn't sitting against dirty fabric. Air the pillow out during the day when you can — draping it over a chair for a few hours helps it dry out from sweat. A light spray of disinfectant on the surface between washes is a common move, and one that shows up a lot is running the pillow through a dryer's sanitize setting to knock down cold and flu germs. Just check your fill can handle the heat before you try it.

A few questions that come up a lot

A few questions that come up a lot

Can pregnancy pillows be washed? Usually, yes — but it depends on the insert. Some brands say hand wash only. Others are fine in a machine on gentle with cold or warm water and mild detergent, as long as your washer and dryer can actually fit them. Check the tag before you commit.

Why does my boyfriend's pillow go yellow? That's a general laundering question, not something specific to pregnancy pillows. The closest advice here is the same rule that applies to your cover: wash it regularly, since covers collect the oils and sweat that cause discoloration, and freshen between washes.

How many weeks pregnant should I use a pregnancy pillow? There's no set timeline — it's about comfort, and that varies. What's worth knowing before you start is that most of these pillows have a removable cover you can wash often and an insert that may need hand washing, so check both first.

What can I do with my old pregnancy pillow? Clean it properly before it goes anywhere: wash or replace the cover, hand wash or spot clean the insert, and dry it completely. What happens after that — storage, passing it on, repurposing — is a separate question.

What to do with an old pregnancy pillow

If you're done with it, give it one last proper clean. Wash the cover, spot clean or hand wash the insert, and make absolutely sure it's dry all the way through before it gets folded, bagged, or stored. A pillow put away damp comes out of storage with mildew, and then it's not useful to anyone.

Once it's clean and dry, you've at least got options. Just don't skip the drying step because you're tired of looking at it.

Same rule applies to the rest of your gear, honestly. Small-kid stuff — baby socks, that first pair of shoes — needs the same kind of simple, regular care routine, and it's a lot easier to stay on top of when someone spells out the actual steps.
