You’ve used your bolster pillow for yoga, meditation, or extra back support on the couch. Over time, it starts to feel less fresh. Sweat, oils, and dust build up, and maybe there’s even a faint odor. You want to clean it, but you’re not sure: can you toss it in the washing machine? Will it lose its shape? What if the cover does not come off? You’re not alone. Many people hesitate to wash their bolster pillows because they’re unsure of the right method.
The good news is, most bolster pillows can be cleaned safely, but only if you follow the correct steps based on the filling and cover type. This guide gives you step-by-step instructions for every type of bolster, including machine-washable, non-removable cover, memory foam, and latex models. You’ll learn how to spot clean, deep clean, dry properly, and maintain freshness, all without damaging your pillow.
Check Washability First
Before any cleaning, determine if your bolster can be washed. Not all bolsters are machine-washable. Material type is the deciding factor.
Know Your Filling Type
The filling inside your bolster determines whether it can handle machine washing.
• Polyester or microfiber fill: usually machine washable
• Cotton or down-alternative fill: may be washable if cover allows
• Memory foam or latex fill: never machine wash
• Zafu (buckwheat hull) insert: spot clean only
Always check the care label. If the label is missing, contact the manufacturer or assume it is not machine washable.
Inspect the Cover
The cover design matters just as much as the filling.
• Removable cover: zippered or sewn with access panel, can be washed separately
• Non-removable cover: must be cleaned in place (common with yoga bolsters like Hugger Mugger)
• Waterproof or padded covers: may require special handling, avoid heat
If the cover cannot be removed and the filling is not washable, only spot clean the surface.
Remove and Wash the Cover
If your bolster has a removable cover, wash it first. This removes surface dirt and protects the inner pillow from unnecessary exposure to water.
How to Wash the Cover
Follow these steps for best results.
- Unzip or unfasten the cover carefully
- Turn inside out to protect outer fabric
- Machine wash on cold or warm water with mild detergent
- Use gentle cycle to prevent shrinking or seam damage
- Air dry flat. Do not tumble dry unless the label explicitly says it’s safe
Wash removable covers every 1 to 2 weeks with regular use, or immediately after spills.
When the Cover Is Not Removable
Some brands design covers to stay on permanently. In that case, never submerge the bolster. Clean only the surface using spot cleaning methods. Never saturate the fabric because moisture can seep into non-washable filling and cause mold.
Pre-Treat Stains Before Washing
Even washable bolsters often have stains from sweat, oils, or spills. Pre-treating helps remove them without repeated washes.
Remove Yellow Sweat Stains
Yellow stains from body oils and sweat are common on frequently used bolsters.
- Mix 2 parts baking soda with 1 part white vinegar into a paste
- Apply to stained area and let sit for 30 minutes
- Blot gently with a damp cloth. Do not scrub
- Let air dry completely before proceeding
Test this mixture on a hidden area first to avoid color damage.
Use Enzyme Detergent for Tough Stains
For stubborn stains that baking soda cannot lift.
- Mix enzyme detergent (like Tide) with warm water to create suds
- Dip a soft brush or sponge and gently scrub the stain
- Let sit for 10 to 15 minutes
- Blot with clean water to remove soap completely
Never soak the entire bolster unless it is confirmed washable.
Machine Wash Washable Bolsters
Only polyester or microfiber-filled bolsters with durable covers should go in the machine. Check your care label first.
Load the Machine Correctly
Proper loading protects both your bolster and your washing machine.
• Place bolster flat in the drum
• Balance the load by adding 2 to 3 clean towels, or wash two bolsters together
• This prevents drum imbalance and damage to the machine
Front-loading machines are safer. Top-loaders with agitators can twist and damage the bolster.
Use the Right Settings
Using incorrect settings can shrink or damage your bolster.
• Cycle: Delicate, Gentle, or Bedding
• Water temperature: Cold to warm (maximum 30 to 40 degrees Celsius)
• Detergent: 1 to 2 tablespoons mild or HE detergent
• Avoid: bleach, fabric softener, hot water
Hot water can melt synthetic fibers or shrink the fabric.
Rinse Thoroughly
Always add an extra rinse cycle. This removes all detergent residue that can attract dirt and cause odors over time.
Dry the Bolster Properly
Improper drying causes mold, mildew, and clumping. This is the most common reason bolsters get ruined.
Air Dry (Safest Method)
Air drying preserves the structure and avoids heat damage.
- Lay flat on a clean, dry surface
- Keep out of direct sunlight. UV rays fade fabric and weaken fibers
- Flip every 6 to 8 hours for even drying
- Drying time: 24 to 72 hours depending on thickness
Press firmly at multiple points to test for dampness. The bolster must be completely dry before use.
Machine Dry (Only for Polyester Fill)
If you must use a dryer, follow these rules.
• Dryer setting: Low or medium heat only
• Add 2 to 3 clean tennis balls or dryer balls to fluff filling and prevent clumping
• Pause every 20 to 30 minutes to reshape and redistribute filling
• Total drying time: several hours. Do not rush
Never use high heat. It can melt synthetic fibers and cause permanent shrinkage.
Clean Non-Washable Bolsters Safely
Memory foam, latex, or bolsters with fixed covers must never be machine washed. Water destroys the structure.
Spot Clean Surface Stains
For bolsters that cannot go in the machine.
- Mix mild detergent with cool water
- Wring cloth until barely damp. Never wet
- Blot the stained area. Do not rub
- Use a second cloth with clean water to remove soap
- Blot dry with a towel
- Air dry completely before use
This method is ideal for yoga bolsters and meditation cushions.
Handle Spills Immediately
Acting fast prevents stains from setting.
• Blot liquid spills with a dry towel. Do not press hard
• Follow with spot cleaning
• Never let moisture sit. It can cause internal mold
Deodorize and Freshen Regularly
You do not need to deep clean every time. Regular freshening keeps your bolster hygienic and extends the time between washes.
Use Baking Soda to Remove Odors
Baking soda neutralizes odors naturally.
- Sprinkle lightly over the surface
- Let sit for 15 to 60 minutes
- Vacuum thoroughly with brush attachment
- This neutralizes sweat acids and absorbs odors
Do this monthly or after sweaty use.
Refresh with Light Mist
A light mist keeps your bolster smelling fresh.
• Mix 10 drops essential oil (like lavender) with 1 cup water
• Spray lightly. Never soak
• Let air dry completely before use
Avoid oils that stain or irritate. Patch test first.
Air Out After Use
• Stand upright or lay flat in a ventilated area
• This prevents moisture buildup from sweat
• This is especially important for yoga and travel bolsters
Daily and Long-Term Care Tips
Proper maintenance keeps your bolster supportive, clean, and long-lasting.
Daily Habits
These simple habits extend the time between deep cleans.
• Shake or pat gently after use to redistribute filling
• Rotate or flip to prevent uneven flattening
• Use a towel or protector during use to reduce skin contact
Weekly Maintenance
• Dust with a lint roller or soft brush
• Inspect for stains and treat early
• Air out in a dry, shaded area
Store Correctly
Proper storage prevents damage and extends lifespan.
• Keep in a cool, dry place. Avoid basements or humid areas
• Do not stack heavy items on top. This causes permanent flattening
• Elevate off the floor to reduce dust and pet hair
• Avoid direct sunlight to prevent fading
Replace When Needed
Even with great care, bolsters wear out. Know when it is time for a new one.
Signs It Is Time to Replace
• No longer springs back after compression
• Deep, permanent dents that will not fluff
• Thin, worn fabric or visible filling through seams
• Persistent musty smell even after cleaning
A well-maintained bolster lasts 5 to 10 years.
Special Cases by Use Type
Different bolsters have different care rules based on how they are used.
Yoga and Meditation Bolsters
Yoga and meditation bolsters often have fixed covers that cannot be removed.
• Hugger Mugger and similar brands: covers are not removable
• Clean only by spot treatment and airing
• Never machine wash. Water damages inner structure
• Use baking soda monthly to absorb sweat odors
Bedroom or Decorative Bolsters
Bedroom bolsters are often easier to clean.
• Often have removable, machine-washable covers
• Entire pillow may be washable if filled with polyester
• Use a bolster protector like a pillowcase to reduce washing frequency
Travel or Portable Bolsters
Travel bolsters need special attention due to frequent use.
• Small size allows hand washing in a sink or tub
• Use waterproof liner in high-sweat environments
• Air dry quickly due to thinner profile
Hand Wash When No Machine
No access to a washer? You can still clean a washable bolster by hand.
Hand-Wash Steps
- Fill bathtub or basin with cool to warm water and mild detergent
- Submerge bolster and gently press. Do not twist or wring
- Drain and rinse with clean water. Repeat until water runs clear
- Roll in a dry towel to press out excess water
- Air dry completely using the flip-and-dry method
This method is only for polyester or microfiber fills with durable covers.

Key Takeaways for Washing Your Bolster Pillow
Washing a bolster pillow correctly starts with knowing your specific type. Polyester and microfiber fills can handle machine washing on gentle cycles with cold to warm water, while memory foam, latex, and buckwheat hull fills require only spot cleaning. Always check the care label before any cleaning attempt, because manufacturer guidance overrides general advice.
The most critical step is proper drying. Air drying is safest and prevents the clumping, mildew, and fiber damage that ruin bolsters. If you must use a dryer, stick to low heat and add tennis balls to fluff the filling. Never skip the extra rinse cycle when machine washing, because leftover detergent attracts dirt and causes odors.
Regular maintenance between washes extends your bolster’s life significantly. Use a protective towel during use, air it out after sweaty sessions, and treat stains immediately. With the right care, a quality bolster pillow lasts 5 to 10 years, staying fresh, supportive, and ready for your daily yoga practice, meditation, or cozy evenings on the couch.
