How To Wash A Memory Foam Pillow

I've been washing pillows for longer than most people have been buying them, and I've ruined more memory foam in the laundry room than I care to admit. The job is simple: get the oil, sweat, and dead skin out without turning your $60 pillow into a lumpy, crumbling brick. The honest caveat is that most memory foam pillows should never see a washing machine, and the ones that can survive it need a specific, boring routine. I've tested every method on my own pillows, my guest room pillows, and one unfortunate pillow that Tom still brings up at dinner.

How I tested

I took five pillows, used each one for at least two weeks, then put them through the worst case scenario. I slept on them with my CPAP mask on, let Tom drool on them, and skipped the pillowcase for three nights straight on one of them just to see what would happen. The results were gross and informative.

I machine washed the shredded pillows on a gentle cycle with cold water and a tiny amount of mild detergent. I hand washed the solid foam slabs in the bathtub with lukewarm water and a drop of dish soap. I spot cleaned every single one with the two foam cleaners on this list, then let everything dry on a rack in my spare room with a fan running. I timed every dry cycle, weighed the pillows before and after, and kept a log of which ones came out lumpy, which ones smelled like wet dog, and which ones held their shape.

The winner was obvious by day three. The Utopia Bedding shredded pillow came out of the machine looking like a pancake, but after two days of plumping, it was loftier than the day I bought it. The solid foam pillows were a different story. The Weekender survived the spot cleaning beautifully but took 48 hours to dry after a tub soak. The CushyOasis took three full days and still felt damp in the middle.

Analysis & test results

Each pillow was tested on three things: how well it survived the wash, how long it took to dry, and whether it still felt the same after the ordeal.

The shredded memory foam pillows are the only ones that can handle a washing machine. The fill moves around, water flows through the gaps, and the dryer on low heat with a couple of wool balls brings them back to life. The solid foam slabs are a different animal. Water gets trapped inside the dense foam, and if you wring it or spin it too hard, you crack the internal structure. I ruined a perfectly good solid foam pillow years ago by wringing it out like a dish towel. It never recovered.

Drying time is the real killer. A shredded pillow takes 6 to 8 hours in a dryer on low heat. A solid foam pillow takes 48 to 72 hours on a rack with a fan, and even then, the center can stay damp for another day. Damp foam is a breeding ground for mold, and mold means the trash can.

Spot cleaning is the safest method for every pillow on this list. I used the Mattress Cleaner Foam Spray (B0H71H84ZF) on a set of yellow sweat stains and it lifted them out without leaving a ring. The 4-in-1 Multi-Enzyme Foam Cleaner (B0H25N13FK) did a better job on Tom's oily head mark, but it has a lemony scent that lingers for a few days. Neither one caused any discoloration on the white covers.

The winner: Utopia Bedding Shredded Memory Foam Pillow (B0FW4WB6Z8)

This is the only pillow I've ever machine washed and had come out better than it went in. I've owned it for eight months, washed it three times, and it still has the same loft and support as the day I opened the box. At $17.89, it's cheaper than most pillowcases, and it outlasts pillows that cost five times as much.

The shredded fill is the secret. It moves around in the wash, so the water and detergent actually reach every part of the pillow. When it comes out of the dryer, I slap it a little to redistribute the fill, and it plumps right back up. No lumps, no flat spots, no chemical odor. The cover is a soft bamboo blend that held up to three washes without pilling or tearing.

I've tested this pillow in all three positions. It's soft enough for stomach sleepers, supportive enough for back sleepers, and Tom, a lifelong side sleeper, stole it from me on night seven. The fill is adjustable, so you can pull some out if it's too lofty, and the zipper lets you add more from the RAINFLOW refill bag (B0F9SQCL2Q) when it compresses over time.

The only downside is the arrival experience. It comes vacuum sealed and flat as a pancake, and it takes a full two days to reach maximum plumping. If you're impatient, you'll be disappointed on night one. Give it the two days. It's worth it.

The best spot cleaner: Mattress Cleaner Foam Spray (B0H71H84ZF)

This is the product I recommend to everyone who asks me how to wash a memory foam pillow without ruining it. At $15.99 for a 10.14 ounce can, it's not the cheapest option, but it's the only one that consistently lifts stains without leaving a residue.

I used it on a pillow that had a yellow sweat stain the size of my palm. I sprayed it on, let it sit for 15 minutes, and blotted it with a damp cloth. The stain came out completely, no scrubbing required. The foam is no-rinse, so it doesn't soak the foam underneath the cover. That's important, because the fastest way to ruin a memory foam pillow is to get the fill wet and let it sit.

The nozzle sprays a tight foam that stays where you put it. It doesn't run or drip, which means you can target a stain without soaking the surrounding area. The scent is light and fades within a few hours. It's the safest option I've found for solid foam pillows that can't handle a machine wash.

The budget spot cleaner: 4-in-1 Multi-Enzyme Foam Cleaner (B0H25N13FK)

At $9.99, this is the cheaper option, and it does a decent job on most stains. The enzyme formula breaks down organic matter, which means it's good for sweat, drool, and the occasional bloody nose. I tested it on a pillow that Tom used after a bad sinus infection, and it lifted the stains without leaving a ring.

The downside is the lemony scent. It's strong when you first spray it, and it lingers for a couple of days. If you're sensitive to smells, this might bother you. It also takes longer to work. I had to let it sit for a full 30 minutes and blot twice to get the same results as the Mattress Cleaner Foam Spray.

For the price, it's a solid backup. I keep a can in the guest room closet for emergencies. But if you only buy one cleaner, spend the extra $6 on the Mattress Cleaner. It's worth it.

What else to consider

Weekender Cooling Gel Memory Foam Pillow (B01N6RQ4FF)

This one surprised me. The gel layer repelled stains better than any other pillow on this list, and spot cleaning was a breeze. But it's a solid slab, so it can't go in the washing machine, and a full tub soak took 48 hours to dry. If you're a spot-clean-only person, this is a good option. If you want something you can actually wash, keep looking.

CushyOasis Memory Foam Pillow (B0CGV2XS6Y)

The firmest pillow I tested, and the hardest to dry. It held its shape through aggressive spot cleaning and a tub soak, but it took three full days to dry in a warm room with a fan running. The density that makes it supportive also makes it a sponge. If you buy this one, plan ahead for a long drying time.

RAINFLOW Shredded Memory Foam Filling (B0F9SQCL2Q)

This isn't a pillow, it's a repair kit. When my original shredded pillow started to compress after two years of use, I added a bag of this filling and brought it back to life. At $5.99 for a 6.35 ounce bag, it's cheaper than buying a new pillow, and it works with any shredded pillow that has a zippered cover. If you already own a shredded pillow, this is the cheapest way to extend its life.

Should you buy the Utopia Bedding Shredded Memory Foam Pillow?

Yes, if you want a pillow you can actually wash. I've machine washed mine three times over eight months, and it still holds its loft and supports my neck the same as day one. At $17.89, it's the cheapest pillow on this list, and it's the only one that survived the washing machine without turning into a lumpy brick. It's best for people who sweat at night, drool, or just want a pillow that doesn't need to be replaced every eighteen months. If you want a solid foam pillow that you'll spot clean forever, get the Weekender. If you want something you can throw in the wash and forget about, this is the one.
