Washing your pillow regularly is essential for hygiene, but doing it wrong can ruin it. This guide walks you through exactly how to wash your pillow based on its filling type—whether down, memory foam, or polyester—so you can enjoy a fresh, clean pillow every night.
Let’s be honest. When was the last time you actually washed your pillow? If you’re like most people, you change your pillowcase every week or so, but the pillow itself? It probably hasn’t seen water in months—or maybe years. That’s a problem. Your pillow collects sweat, dead skin cells, oils, and dust mites night after night. Learning how to wash your pillow the right way is one of the simplest things you can do to improve your sleep hygiene and extend the life of your bedding.
The good news is that washing a pillow isn’t complicated. But it does require a little know-how. Different pillow types need different approaches. Tossing a memory foam pillow into the washing machine, for example, can destroy it. Washing a down pillow incorrectly can leave it clumpy and flat. In this guide, we’ll cover everything you need to know so you can clean your pillows with confidence.
Key Takeaways
- Check the care label first: Always read the manufacturer’s tag before washing to determine if your pillow is machine washable or requires hand washing.
- Different fillings need different care: Down and polyester pillows can usually go in the machine, but memory foam and latex pillows should never be submerged in water.
- Use a gentle cycle with cold or warm water: Hot water can damage pillow fillings and cause shrinkage, so stick to a mild detergent on a delicate setting.
- Dry thoroughly to prevent mold: Damp pillows breed bacteria and mildew. Use low heat with dryer balls and allow extra drying time to ensure no moisture remains.
- Wash pillows every 3 to 6 months: Regular washing removes sweat, dead skin cells, and allergens that accumulate over time.
- Use a pillow protector between washes: A zippered protector acts as a barrier against stains and extends the life of your pillow between cleanings.
Quick Answers to Common Questions
Can I wash all pillows in the washing machine?
No. Memory foam and latex pillows should never be submerged in water. Down and polyester pillows are generally machine safe. Always check the care label before washing.
How often should I wash my pillow?
Aim to wash your pillow every three to six months. If you have allergies or sensitive skin, washing it every two to three months is even better.
Can I use bleach when washing pillows?
Avoid bleach as it can weaken the fabric and damage the filling. Stick to a mild liquid detergent and consider adding baking soda for extra cleaning power.
Why does my pillow smell bad after washing?
A musty smell after washing usually means the pillow wasn’t dried thoroughly. Moisture trapped inside the filling leads to mildew. Make sure your pillow is completely dry before using it again.
Do I need to wash a new pillow before using it?
It’s a good idea to wash a new pillow before use, especially if you have allergies. Manufacturing chemicals and dust from packaging can irritate sensitive skin and airways.

Why You Need to Wash Your Pillow Regularly
Think about it. Your face presses against your pillow for roughly eight hours every night. Over time, that pillow absorbs a surprising amount of moisture, body oils, and allergens. Studies have shown that an unwashed pillow can harbor millions of dust mites after just a few months. These microscopic creatures thrive in warm, humid environments and can trigger allergies, asthma, and skin irritation.
Beyond dust mites, your pillow absorbs sweat and saliva. This creates the perfect breeding ground for bacteria and mold. If you’ve ever noticed a musty smell coming from your pillow, that’s a clear sign it’s time for a wash. Washing your pillow every three to six months keeps it fresh, clean, and supportive. If you suffer from allergies or have sensitive skin, washing even more frequently can make a noticeable difference.
How to Check Your Pillow’s Care Label
Before you do anything, flip your pillow over and check the care tag. This small label tells you exactly how the manufacturer recommends cleaning your pillow. Look for symbols or text that indicate whether the pillow is machine washable, hand wash only, or spot clean only. The care tag also tells you which filling material is inside.
Common Pillow Filling Types and Their Washing Needs
- Down and feather pillows: These can typically be machine washed on a gentle cycle with a mild detergent.
- Polyester fill pillows: These are the easiest to wash. They handle machine washing well and dry relatively quickly.
- Memory foam pillows: Never submerge these in water. They require spot cleaning or a baking soda deodorizing method instead.
- Latex pillows: Like memory foam, latex should not be soaked. Hand wash gently or spot clean only.
- Buckwheat hull pillows: Empty the hulls first, then wash the cover separately. The hulls themselves should not get wet.
If you’ve lost the care tag, identify the filling material and follow the guidelines above. When in doubt, err on the side of caution and use a gentler cleaning method.
How to Wash Your Pillow in a Washing Machine
For pillows that are machine safe, this is the most thorough and convenient method. Start by removing the pillowcase and any protective covers. If your pillow has stains, pre-treat them with a small amount of mild detergent or a paste made from baking soda and water. Let it sit for about 15 minutes before washing.
Step-by-Step Machine Washing Instructions
- Load two pillows at a time: Adding a second pillow helps balance the washing machine drum and ensures both pillows get cleaned evenly.
- Use a gentle or delicate cycle: Aggressive cycles can damage the stitching and cause the filling to shift or clump.
- Use warm or cold water: Hot water can break down the filling and shrink the fabric. Warm water is fine for down and polyester pillows.
- Add a mild liquid detergent: Avoid fabric softeners, as they can coat the filling and reduce loft. Use about half the amount you would normally use for a load of laundry.
- Run an extra rinse cycle: This ensures all soap residue is removed, which can otherwise cause stiffness or skin irritation.
If you’re dealing with a particularly stubborn odor, you can add half a cup of baking soda during the wash cycle for extra deodorizing power.
How to Wash Your Pillow by Hand
Some pillows aren’t suitable for the washing machine. Hand washing is the safer option for latex pillows, delicate down pillows, or any pillow you’re unsure about. Fill a large basin, bathtub, or sink with lukewarm water and add a small amount of mild detergent.
Hand Washing Steps
Submerge the pillow in the water and gently press it to work the soapy water through the filling. Avoid twisting, wringing, or scrubbing aggressively. Let the pillow soak for 10 to 15 minutes, then drain the dirty water. Refill the basin with clean water and press the pillow again to rinse. Repeat until the water runs clear. Gently press out as much water as possible—never wring the pillow. Then proceed to the drying phase.

How to Spot Clean a Memory Foam Pillow
Memory foam and water don’t mix well. Submerging a memory foam pillow can break down its structure and ruin its supportive qualities. Instead, spot cleaning is your best bet.
Spot Cleaning Method
Mix a small amount of mild detergent with water. Dip a clean cloth into the solution and wring it out so it’s damp, not soaking. Gently blot any stained areas on the pillow surface. Don’t rub—blotting lifts the stain without pushing it deeper into the foam. Once the stain is treated, wipe the area with a clean, damp cloth to remove any soap residue. Let the pillow air dry completely in a well-ventilated area, away from direct sunlight.
For general freshening between cleanings, sprinkle baking soda over the pillow surface and let it sit for 30 minutes to an hour. The baking soda absorbs odors naturally. Vacuum the powder off thoroughly using an upholstery attachment.
How to Dry Your Pillow Properly
Drying is arguably the most important step. A damp pillow is a magnet for mold and mildey. Even if your pillow feels dry on the outside, moisture can linger inside the filling. Take your time with this step.
Drying in a Machine Dryer
Place the pillow in the dryer on a low heat setting. Add two or three clean tennis balls or dryer balls to the dryer. These bounce around and help break up clumps in the filling while restoring loft. Drying can take one to two hours depending on the pillow type and thickness. Remove the pillow periodically and feel the center to check for any remaining dampness. Don’t stop until it’s completely dry inside and out.
Air Drying
If you don’t have a dryer or prefer to air dry, lay the pillow flat on a clean, dry surface in a well-ventilated area. Flip the pillow every few hours to ensure even drying. On a sunny day, placing the pillow outside can speed things up naturally. UV rays from the sun also help kill bacteria. However, avoid leaving memory foam or latex pillows in direct sunlight for extended periods, as this can degrade the material.

Tips to Keep Your Pillow Fresh Between Washes
Washing your pillow is great, but you can stretch the time between washes with a few smart habits. Always use a pillow protector underneath your pillowcase. This zippered cover blocks sweat, oils, and allergens from reaching the pillow itself. Wash the protector every one to two weeks along with your pillowcase.
Fluff your pillow every morning to restore its shape and allow air to circulate through the filling. If your pillow starts to smell between washes, a light sprinkle of baking soda left for 30 minutes and then vacuumed off works wonders.
When it’s time to replace your pillow, make sure you choose the right pillow for your sleep style and preferences. A good-quality pillow with proper care can last two to five years depending on the filling type.
Conclusion
Knowing how to wash your pillow the right way is a small habit that makes a big difference. It keeps your sleeping environment clean, reduces allergens, and helps your pillow last longer. The key is matching your washing method to your pillow’s filling type, using gentle cycles and mild detergents, and—most importantly—drying it completely. Set a reminder to wash your pillows every three to six months. Your skin, your sinuses, and your sleep quality will thank you.
Frequently Asked Questions
How long does it take for a pillow to dry in the dryer?
It typically takes one to two hours on a low heat setting. Add tennis balls or dryer balls to speed up the process and prevent clumping. Always check the center of the pillow for remaining dampness before removing it.
Can I wash feather pillows the same way as down pillows?
Yes, both feather and down pillows can be machine washed on a gentle cycle with warm water and mild detergent. The key difference is that feather pillows may take longer to dry because feathers are denser than down.
What’s the best detergent for washing pillows?
Use a mild, fragrance-free liquid detergent. Avoid fabric softeners and bleach, as these can coat the filling, reduce loft, and potentially irritate your skin.
Can I wash my pillow if it doesn’t have a removable cover?
Yes, you can wash a pillow without a removable cover. Just make sure the filling type is appropriate for washing and use a gentle cycle to protect the pillow’s structure.
How do I know when it’s time to replace my pillow instead of washing it?
If your pillow is lumpy, flat, or no longer supportive after washing, it’s time for a replacement. Fold the pillow in half and see if it springs back. If it stays folded, the filling has lost its resilience.
Is it safe to wash two pillows at the same time?
Yes, washing two pillows together actually helps balance the washing machine drum. This ensures both pillows get cleaned evenly and prevents the machine from becoming unbalanced during the spin cycle.
