How to Clean Wool Pillows: Easy Hacks for Fresh Bedding
You spend a third of your life in bed. That’s more time than you’ll spend in meetings, traffic, or even with your family. So, the question is, what are you laying your head on? Clean bedding isn’t just about fresh linen or a puff of lavender spray. It’s about hygiene. Sleep quality. And the quiet confidence that your sanctuary doesn’t harbour allergens, dust, or last week’s stress.
Wool pillows are breathable, hypoallergenic, and thermoregulating. Perfect for hot sleepers, allergy sufferers, or anyone with a taste for refined comfort. But here’s the catch: unlike synthetic or cotton pillows, wool requires a different kind of care. Precision over convenience. Respect over recklessness.
Unlike synthetic pillows that you can toss into a machine, or cotton pillows that surrender easily to suds, wool needs gentler hands. And it’s worth it. Because when you clean wool pillows the right way, you’re not just refreshing fabric. You’re preserving a natural miracle.

Let’s walk through how to clean, dry, and maintain your wool pillows without damaging their natural fibre or compromising on comfort.
Why Cleaning Wool Pillows Properly Matters
Wool pillows are different. Unlike their synthetic counterparts, they don’t hide behind fake softness or chemical fluff. They’re made from nature’s most miraculous fibre, which is resilient, breathable, and self-regulating. But even nature needs a little help staying clean. Wool is naturally resistant to bacteria and dust mites, but it’s not invincible. Over time, unwashed wool can clump, flatten, and lose the very qualities that made you fall in love with it. Here’s why cleaning wool pillows matters — really matters:
-
You’re Protecting the Lifespan of the Pillow: It shifts, adjusts, and supports. But when its fibres are weighed down by grime and moisture, they start to clump together. That luxurious loft will collapse. The bounce will be gone. Regular, gentle cleaning helps preserve the structure of the wool , so your pillow stays plump, breathable, and supportive for years to come.
-
You’re Preserving Its Natural Allergy-Resistant Qualities: One of the main reasons people switch to wool pillows is because they’re hypoallergenic. Dust mites hate wool. Bacteria struggle to thrive in it. But that natural defence system weakens when the wool is neglected. Moisture, body oils, and dust can create a breeding ground for allergens, unless you intervene. Curious about the science behind it? Read the allergy-friendly benefits of wool pillows.
-
You’re Eliminating Odours Before They Set In: There’s a certain kind of betrayal when your pillow begins to smell off. Sweat, skin oils, and atmospheric pollutants don’t just vanish. They embed themselves into the fibres, slowly transforming your pillow from sanctuary to source of subtle discomfort. Cleaning neutralises those odours at the root, not just masks them with fragrance.
-
Better Bedding = Better Sleep: When your bedding smells fresh and feels clean, you sleep better. Your body relaxes when your environment feels safe. A clean wool pillow isn't just about hygiene; it’s an invitation to rest, to truly switch off.
Can You Wash Wool Pillows?
Wool pillows aren’t like your everyday bedding. They’re an investment in your sleep. A product of nature’s engineering that is breathable, moisture-wicking, and they deserve to be treated accordingly. Unlike synthetic or cotton pillows, wool pillows should not be tossed into the washing machine without a second thought. Doing so risks damaging the delicate crimped structure of wool fibres; the very structure that allows it to regulate temperature, stay breathable, and spring back into shape after each night. Instead, wool pillows call for a slower, more thoughtful approach. One that respects the integrity of the material.
Key Considerations Before Washing a Wool Pillow:
Before you reach for the detergent, pause. Look. Feel. Read the label. Not all wool pillows are built the same, and the wrong method can unravel the benefits you paid for.
1. Spot Cleaning vs. Full Wash – Know When to Use Each
-
Spot Cleaning is your first line of defence- perfect for small spills, drool patches, or sudden stains. Quick, targeted, and less invasive.
-
Full Washing should be reserved for seasonal deep cleans, or if the pillow has absorbed odours, sweat, or has lost its freshness.
2. Avoid Harsh Chemicals
The structure of wool is protein-based, just like your hair. Harsh detergents, bleach, or enzyme-based cleaners can break down these natural proteins, causing the fibres to weaken, felt, or lose their bounce.
Instead, always use a pH-neutral detergent or one specifically formulated for wool. These are gentle enough to clean without stripping away the natural lanolin — the waxy substance that gives wool its odour-resistant and moisture-managing magic.
3. Air Drying Is Non-Negotiable
High temperatures can cause the fibres to shrink and felt; a process that makes the pillow dense, lumpy, and almost impossible to recover. Forget the tumble dryer. Air drying is essential. Lay your pillow flat, away from direct sunlight, in a well-ventilated space. Allow nature to do what it does best — slowly, gently, effectively.
4. Read the Label
The term wool pillow is a wide umbrella. Yours might be:
-
100% pure wool
-
Wool-blend with synthetic fibres
-
Wool encased in organic cotton or bamboo
-
Wool clusters with removable covers
Each variation has its own care requirements. Some covers are machine washable while the inner wool filling is not. Others may allow gentle machine washing under specific conditions.
If your wool pillow is from a reputable brand (like Lister Cartwright), it will come with detailed care instructions. Follow them religiously.
In short, yes, wool pillows can be cleaned, but they need more than just soap and water. And when you treat them right, they’ll continue to cradle your dreams night after night, season after season.
How to Clean Wool Pillows
1. Spot Cleaning
Best for: Minor stains and light odours
Steps:
-
Blot the affected area with a damp cloth — lukewarm water only.
-
Mix a small amount of wool detergent with water.
-
Gently dab the stained area using a clean sponge or cloth. Never rub.
-
Rinse by blotting with clean water.
-
Air dry flat, away from sunlight or heat.
2. Hand Washing
Best for: Deep cleaning & odour removal (every 6–12 months)
Steps:
-
Fill a bathtub or basin with cold or lukewarm water.
-
Add a small amount of wool-safe detergent.
-
Submerge the pillow gently and press — don’t wring or twist.
-
Let it soak for 10–15 minutes.
-
Drain water and rinse until detergent is gone.
-
Press out excess water by rolling in a towel.
-
Lay flat on a dry towel in a well-ventilated space to air dry.
3. Machine Washing
Only if approved by the manufacturer
Yes, some wool pillows are machine washable — but only under strict conditions.
Steps:
-
Use a Gentle Wool Cycle – cold water, low spin.
-
Add a wool-friendly detergent — no harsh chemicals.
-
Place the pillow in a pillowcase or mesh bag to protect the fibres.
-
No fabric softener – it coats the fibres, reducing breathability.
-
Skip the dryer. Air dry flat, always.
Best Practices for Maintaining Wool Pillows
Unlike synthetic fills that flatten with time or cotton pillows that cling to every bit of moisture in the air, wool breathes. It regulates. It adapts. But to keep it doing so for years, a little care goes a long way. Here’s how to keep your wool pillows fresh, fluffy, and fully functional — season after season.
1. Use Pillow Protectors
A high-quality, breathable pillow protector is the unsung hero of bedding hygien. It protects your pillow from:
-
Skin oils and sweat that can seep through the pillowcase
-
Accidental spills from that cup of tea on a lazy Sunday morning
-
Invisible environmental particles like dust, pollen, or pet dander
Opt for natural fabrics like cotton or bamboo. Synthetic covers may trap heat and moisture, compromising the wool’s natural breathability. Choose protectors with zip closures for full coverage and easy removal during wash days.
2. Air Out Regularly
In the UK, with its damp winters, mild springs, and varying humidity levels, moisture can accumulate within bedding over time, even without visible stains.
That’s why monthly airing is vital.
-
Take your pillows outside on a dry, breezy day — ideally under shade.
-
Avoid placing them in direct sunlight, which can weaken natural fibres.
- Let the wind do what machines can’t — remove trapped moisture, eliminate stale odours, and reset the pillow’s freshness.
This practice also helps prevent mould and mildew, especially if you live in a high-humidity environment or keep your windows closed often.
3. Air Dry Properly After Cleaning
After any kind of wash, spot, hand, or machine (if allowed) — wool pillows must be dried properly. Not just to remove moisture, but to preserve the inner structure.
-
Lay Flat on a Clean Towel: This prevents the wool from shifting to one side or clumping at the base.
-
Flip occasionally: Helps even out the drying and reduces chances of musty odours.
-
Keep in a Well-Ventilated Area: An airy space speeds up drying without risking overheating.
Whatever you do, don’t hang the pillow by its ends, it’ll drag the wool down and distort the shape permanently.
4. Avoid Direct Heat & Sunlight
You might be tempted to use a tumble dryer on low heat or leave the pillow out under the full sun to "speed things up."But wool plays a different game. High temperatures and UV exposure can shrink the fibres, damage the lanolin, and lead to matting — a condition where the wool compresses into a hard, unbreathable lump. Instead, be patient. A slow dry is a safe dry. And the reward is a pillow that stays lofty and functional for years.
5. Store in a Dry, Breathable Space. Not in Plastic Bags!
Whether you're rotating pillows between seasons or saving spares for guests, storage matters.
-
Never use airtight plastic bags or containers. These trap moisture and create the perfect breeding ground for mildew.
-
Use cotton storage bags or breathable boxes.
-
Add a natural moisture absorber like silica gel packs, cedar chips, or lavender sachets to help preserve freshness and ward off pests.
6. Fluff Pillows Weekly
Unlike synthetic pillows that puff up with a tumble, wool pillows need a little manual care.
Weekly fluffing is simple and effective:
-
Gently shake your pillow to redistribute the wool filling.
-
Press and knead the edges to even out any compression.
-
Give it a few firm pats to restore its original loft.
This habit helps maintain the pillow’s support and prevents the wool from settling unevenly over time.
7. Invest in High-Quality Wool Pillows
And here’s a truth we don’t talk about enough: not all wool pillows are made equal. The quality of wool — its origin, how it’s processed, whether it’s encased in breathable fabrics- determines how well it performs and how long it lasts.
Poorly made wool pillows may:
-
Clump prematurely
-
Absorb more moisture than they release
-
Require frequent replacement
On the other hand, a well-crafted pillow, like those in the Lister Cartwright Pillow Collection, is designed to endure, using premium-grade British wool, thoughtful construction, and eco-conscious materials. It's not just a pillow. It's a promise of better rest, night after night.
Maintaining a wool pillow isn’t difficult. It’s deliberate. A little spot cleaning here. A monthly airing there. A gentle hand wash every so often. These aren’t chores, they’re investments. In longevity. In comfort. In peace of mind. You don’t need to overhaul your routine to get the best from your pillow. Just a few intentional habits can ensure it stays as fresh, fluffy, and functional as the day you brought it home. In return, it rewards you with night after night of quality sleep; cool when it’s warm, warm when it’s cool, and always clean.
So, whether you’re a minimalist or a maximalist, a light sleeper or a deep dreamer, one thing remains true: Better sleep begins with better care. And better care begins with choosing better products. Explore the Lister Cartwright Bedding Collection here.
