How to Clean Pillows: A Complete Guide for Every Type
Enjoy fluffier, allergy-free bedding night after night with simple home care tips.
A good night’s sleep depends on more than just a comfortable mattress—clean pillows are essential for both comfort and hygiene. Pillows can harbor sweat, oils, dust mites, and allergens, making regular cleaning an important homekeeping routine. Whether your pillows are made of memory foam, natural down, or synthetic fibers, this comprehensive guide will walk you through the best cleaning methods to keep them fresh, fluffy, and supportive.
Why Cleaning Your Pillows Matters
Over time, pillows accumulate dead skin cells, body oils, sweat, drool, and environmental dust. These conditions can attract dust mites and bacteria, which not only decrease the pillow’s lifespan but can also affect your health by irritating allergies and skin. A regular pillow cleaning schedule can:
- Improve sleep quality by reducing allergens and maintaining pillow support.
- Extend the life of your pillows with proper care techniques.
- Enhance comfort by keeping pillows fresh, fluffy, and odor-free.
How Often Should You Clean Your Pillows?
The recommended frequency for cleaning your pillows depends largely on pillow type, usage, and whether you use protective pillow covers. As a general guideline:
- Wash pillowcases: Weekly, with your bedding.
- Clean pillows themselves: Every 3-6 months, or at least twice a year for optimal hygiene.
- Spot clean stains: As soon as they appear to prevent set-in marks or odors.
Step-By-Step Guide: How to Clean Every Type of Pillow
Understanding Pillow Construction
Most pillows have two main parts:
- Outer cover: This removable fabric layer includes your pillowcase and often a zippered protector.
- Inner core: The fill material (such as feathers, down, polyester, or memory foam) that provides support and loft.
Both layers need difference cleaning techniques. Always check the manufacturer’s care label before attempting any cleaning routine, as certain materials require extra caution.
How to Clean Memory Foam Pillows
1. Routine Maintenance
The outer cover of memory foam pillows can be removed and laundered with regular bedding. However, the memory foam core should not be machine washed, as agitation can break down its structure. Instead, follow these steps:
- Wash the cover: Remove and launder according to the care label instructions. Warm water and mild detergent are generally safe.
- Vacuum regularly: Use a handheld vacuum to remove dust, hair, and debris from the foam surface.
2. How to Spot Clean Memory Foam Pillows
For stains such as sweat, saliva, or accidental spills, prompt spot cleaning helps:
- Remove pillowcase and any covers.
- Blot up excess liquid with a towel or paper towel—do not rub, as this spreads the stain.
- Mix a solution of mild liquid soap and cool water. Using a clean sponge, gently dab (do not soak) the stained area in a circular motion.
- Wipe away soap residue with a clean, damp cloth.
- Press gently with a dry towel to absorb moisture. Place pillow in a well-ventilated area, away from direct sunlight and heat, until completely dry.

3. Deodorizing Memory Foam Pillows
To remove odors between washes:
- Lay pillow on a flat surface.
- Sprinkle a generous layer of baking soda over the entire surface.
- Leave the baking soda on for 1-3 hours, ideally in indirect sunlight.
- Vacuum thoroughly to remove all baking soda particles.
- Flip the pillow and repeat for the other side if needed.
4. Deep Cleaning (Hand Wash) Memory Foam
- Remove all cases and covers.
- Fill a bathtub or large sink with lukewarm water and a small amount of gentle laundry detergent.
- Submerge the foam pillow and gently squeeze to encourage soapy water to pass through. Avoid twisting or wringing, as this can tear the foam.
- Rinse thoroughly in fresh water until all soap is removed.
- Gently press out as much water as possible, then let air dry flat on a clean, ventilated surface. Flip periodically for even drying. It may take up to 24 hours to dry completely.
What to Avoid:
- Do not use bleach or harsh chemicals, which can degrade memory foam.
- Avoid machine washing or drying the core, as agitation and heat can destroy structure.
How to Clean Down and Feather Pillows
Natural down and feather pillows are known for their softness but need gentle care.
- Check for seams or tears before washing. Mend any holes to avoid losing filling.
- Use a large, front-loading washer (top-load agitators can damage the filling).
- Wash two pillows at a time to balance the drum and ensure even cleaning.
- Select the gentle or delicate cycle with cold or warm (never hot) water and a small amount of mild detergent.
- Optional: Add an extra rinse cycle to ensure all soap is removed.
- Drying: Tumble dry on low heat with clean tennis balls or dryer balls to fluff the filling and prevent clumping. This may take several hours.
Check that pillows are completely dry to prevent mold. Give a few good shakes to redistribute filling.
| Pillow Type | Machine Washable? | Special Instructions |
|---|---|---|
| Memory Foam | No (core), Yes (cover) | Hand wash foam core only; use mild detergent. Air dry thoroughly. |
| Down/Feather | Yes | Use gentle cycle and cold/warm water. Tumble dry low with dryer balls. |
| Polyester/Synthetic | Yes | Wash 2 at a time for balance; gentle cycle. Dry completely on low. |
| Latex Foam | No | Spot clean only. Never submerge latex in water. |
How to Clean Polyester and Synthetic Pillows
Most synthetic-fill pillows (such as polyester or microfiber) are easiest to clean:
- Machine-wash on a gentle cycle in warm water using mild detergent.
- Wash two pillows at a time to keep the machine balanced.
- Tumble dry on the lowest heat setting with dryer balls or a clean tennis ball to help restore fluff.
- Ensure pillows are thoroughly dry before use; synthetic fibers can trap moisture, leading to mold if not dried properly.
General Tips for All Pillow Types
- Always follow care labels: Manufacturer’s instructions provide the safest guidance for each pillow type.
- Remove stains promptly: Address spills or spots as soon as possible for best results.
- Use pillow protectors: A zippered protector beneath your pillowcase offers an extra barrier against dirt and allergens.
- Don’t overload your washer: Give pillows space to move freely for thorough cleaning.
- Shake and fluff pillows regularly: This redistributes filling and keeps pillows plump.
How to Refresh Pillows Between Washes
- Air out pillows outdoors on a dry, sunny day—sunlight helps kill dust mites and bacteria.
- Give an occasional fluff by hand or low in the dryer (no heat) for aeration.
- A light spray of fabric freshener can add a pleasant scent, but ensure the pillow is thoroughly dry afterward.
When Should You Replace Your Pillows?
No matter how well you clean your pillows, they eventually lose their support and can become a breeding ground for allergens. Watch for these signs that it’s time for a replacement:
- Your pillow no longer holds its shape and remains flat after fluffing.
- You notice persistent odors or stains that do not wash out.
- You wake up with neck pain or allergy symptoms that go away during the day.
A good rule of thumb is to replace pillows every 1-2 years for synthetics, or every 2-3 years for high-quality down or foam pillows.
How to Clean Specialty and Decorative Pillows
Decorative pillows, or those with embellishments or non-removable covers, require special care:
- Spot clean only: Use mild soap and water with a white cloth; test an inconspicuous area first.
- Vacuum with an upholstery attachment: This removes dust and surface debris.
- Dry clean if directed: Some pillows, especially with delicate fabrics, require professional care.
Troubleshooting Common Pillow Cleaning Problems
- Yellow stains: Usually caused by perspiration or body oils. Try repeated gentle washing and sun-drying. Use a pillow protector moving forward.
- Lumpy or flat pillows: Fluff vigorously after drying; dryer balls can help redistribute fill. Over time, fiber breakdown is inevitable, and replacement is the best solution.
- Persistent odor: Ensure the pillow is fully dry before use; repeat odor removal steps with baking soda.
