You know that moment when you flip your pillow over, expecting the “cool side,” and instead get hit with a faint whiff of… mystery? Yeah, that. Let’s talk about it.
We wash our sheets, maybe even our comforters, but pillows? Those poor things rarely get the love they deserve — even though they’re basically sweat-and-drool sponges we nuzzle eight hours a night. If you’ve ever wondered how to make your pillows white again and get rid of that stubborn musty smell, you’re in the right place.
Let’s walk through how to bring your tired, yellowed pillows back from the dead — and have them smelling like a lavender dream while we’re at it.
First, The (Gross) Truth About Pillows
Okay, brace yourself. Over time, pillows can accumulate sweat, skin oils, dead skin cells, dust mites, and bacteria. Some estimates say your pillow might double in weight over a couple of years. Double. As in, half pillow, half who-knows-what.
And no, changing the pillowcase doesn’t cut it. It’s like putting a fresh sheet on a stained mattress and calling it clean. So if your pillow looks more like a prop from a crime scene than a place of comfort — it’s time.
Step 1: Check the Tag (Seriously, Read It)
Before you throw your pillow into the washer like a hero on autopilot, pause. Check the label. That tiny, scratchy tag holds the secret to not ruining your pillow forever.
-
Feather/Down pillows usually need a gentle cycle and dryer-safe drying.
-
Memory foam? Do not machine wash. Spot clean only, or you’ll end up with a lumpy, sad blob.
-
Synthetic/down-alternative pillows are usually washer-safe, but again — read the label to be safe.
If the care instructions are gone (because who keeps those?), err on the side of gentle.
Step 2: Spot Treat the Ugly Stuff
Yellowing around the edges? Weird odors that seem to return after washing? Don’t just hope the machine will fix it — it won’t.
Here’s what to do:
-
Baking soda + a splash of water makes a great paste for yellow stains. Rub it in, let it sit for 30 minutes.
-
White vinegar spray (equal parts vinegar and water) can zap mildew smell. Just don’t soak the whole pillow in it.
-
A few drops of tea tree or eucalyptus oil can add a clean scent while kicking bacteria to the curb. Don’t go overboard, or your pillow might end up smelling like a spa exploded.
Step 3: Mix Up the Cleaning Cocktail
This part feels like kitchen science, but trust me — it works.
For machine-washable pillows, fill your washer with hot water (or the hottest allowed per the tag), then add:
-
1 cup of washing soda
-
1/2 cup of borax
-
1 cup of regular detergent (preferably fragrance-free if you’re sensitive)
-
Optional: 1/2 cup white vinegar in the rinse cycle

Let the pillows soak in this magic for at least 30 minutes before running the wash cycle. If your machine doesn’t allow soaking — you can do this step in a bathtub or big sink.
Step 4: Wash Smart — Not Just Fast
Wash two pillows at once if you can. It balances the load and helps the machine spin evenly.
Use the gentle or bulky setting, warm water, and an extra rinse cycle. That last part matters — detergent can get trapped deep inside, and nothing says “bad dreams” like soap residue clinging to your face.
And whatever you do, don’t use fabric softener. It actually coats the pillow and locks in grime. Gross.
Step 5: Dry Like a Champ
This is where most people mess up. Damp pillows = mold risk = smelly disappointment.
-
Toss your pillows into the dryer on low heat with a couple of clean tennis balls or dryer balls. They’ll fluff the pillows and help them dry evenly.
-
Check every 30 minutes, give them a shake, and don’t rush. Pillows can feel dry on the outside but still hold moisture inside.
-
If you’ve got the space and sunshine, laying them out in the sun works wonders. Bonus: UV rays help disinfect and deodorize.
If your dryer is older or temperamental, alternate between machine drying and air drying. Better safe than mildewy.
Bonus: Make ‘Em Smell Like Heaven
Want your pillows to smell like they came out of a boutique hotel?
Try this DIY pillow spray:
-
1/2 cup distilled water
-
1 tablespoon witch hazel or rubbing alcohol
-
10–15 drops of your favorite essential oil (lavender and lemon is a relaxing mix)
Lightly mist the pillow after it’s completely dry. Not before — otherwise, you’re reintroducing moisture and inviting mildew back in like an old friend.
And if you’re really serious? Get zippered pillow protectors. They’re like pillowcases on steroids. Washable, breathable, and they keep the actual pillow cleaner for longer.
When to Say Goodbye (Yes, Pillows Have an Expiration Date)
Even the cleanest pillow has a lifespan. If it stays flat and lifeless after washing, or if you fold it in half and it doesn’t bounce back — it’s time to retire it.
Most pillows last 1 to 2 years max. Memory foam maybe a bit longer if well cared for. Don’t wait until it smells like your dog’s favorite toy.
Sweet Dreams Are Made of… Clean Pillows
There’s something wildly satisfying about laying your head on a pillow that smells fresh, looks white again, and doesn’t make you question your life choices.
Sure, it takes a bit of effort. But so does decent sleep — and honestly, a clean pillow is a small but mighty upgrade for your health, skin, and sanity.
So go ahead. Give those forgotten fluffballs the spa day they deserve. Your face (and your dreams) will thank you.
