A memory foam pillow can make your bed feel more supportive and comfortable, but cleaning it is not as simple as tossing it in with the sheets. Foam reacts differently than cotton, polyester, or down alternative fill. Too much water, heat, or machine agitation can damage the foam and shorten the life of the pillow.
If you are asking can you wash memory foam pillows, the safest answer is this: you can clean them, but you usually should not machine wash the foam core. Most memory foam pillows should be spot cleaned, gently hand washed only when needed, and dried fully before use.
This guide explains what to do, what to avoid, and when it may be time to replace your pillow instead of trying to clean it again.
Can you wash memory foam pillows?
Yes, you can clean memory foam pillows, but the method matters. The foam itself should usually be treated gently. For most pillows, the best routine is to wash the pillowcase often, wash the removable cover according to the care label, and spot clean the foam when needed.
If you are asking can you wash a memory foam pillow because of a spill, sweat mark, or odor, start with the least aggressive method first. Spot cleaning is usually enough for small stains. A deeper hand wash may be needed for larger messes, but only if the care label allows it.
Viscosoft's insight
With memory foam, the goal is not to soak it unless you truly need to. Clean the surface, remove the stain or odor, and give the foam plenty of time to dry before putting it back on the bed.
Can you machine wash memory foam pillows?
In most cases, no. If you are wondering can you machine wash memory foam pillows, the foam core should usually stay out of the washer. The movement inside a washing machine can break down the foam, create cracks, or leave the pillow uneven.
The same answer applies if you are asking can you wash memory foam pillows in the washer. A washer is usually too rough for solid memory foam and many shredded memory foam designs. Even if the foam survives the cycle, it can be very hard to dry fully afterward.
If your pillow has a removable cover, that cover may be machine washable. Always check the care label first. The cover and the foam core often have different care instructions.
Memory foam pillow cleaning guide
| Pillow part or problem | Best cleaning method | What to avoid |
|---|---|---|
| Pillowcase | Wash regularly with your sheets | Letting oils and sweat build up |
| Removable pillow cover | Machine wash only if the care label allows it | High heat unless the label says it is safe |
| Small stain on foam | Spot clean with mild detergent and water | Scrubbing hard or soaking the whole pillow |
| Odor | Air out, then use baking soda and vacuum gently | Perfume sprays or heavy moisture |
| Solid memory foam core | Spot clean or gently hand wash if allowed | Washer, dryer, wringing, or direct high heat |
| Shredded memory foam pillow | Follow the care label; spot clean when unsure | Washing loose foam fill unless the brand allows it |
Can you wash memory foam pillows in the washing machine?
If you are asking can you wash memory foam pillows in the washing machine, the answer is usually no for the foam itself. Washing machines are built for fabrics that can handle tumbling and spinning. Memory foam is not that kind of material.
The foam can tear, crack, or lose its shape in the washer. It can also hold water deep inside the pillow, which makes drying slow and increases the risk of mildew if the pillow is used too soon.
If the pillow has a removable cover, unzip it and check the tag. The cover may be safe to wash, even when the foam is not.
Can you put a memory foam pillow in the washer?
If your question is can you put a memory foam pillow in the washer, treat the answer as no unless the care label clearly says otherwise. This is especially important for solid memory foam pillows.
A washer can be too aggressive for the foam structure. Even a gentle cycle may create stress that the pillow was not designed to handle. When in doubt, wash the cover and spot clean the foam instead.
How to spot clean a memory foam pillow
Spot cleaning is the best first step for most stains. It uses less water, gives you more control, and helps protect the shape of the pillow.
Here is a simple process:
- Remove the pillowcase and removable cover.
- Vacuum the pillow gently to remove dust or hair.
- Mix a small amount of mild detergent with cool or lukewarm water.
- Dab the stained area with a clean cloth.
- Work from the outside of the stain toward the center.
- Blot with a second damp cloth to remove leftover soap.
- Press gently with a dry towel to remove extra moisture.
- Let the pillow air dry fully before using it again.
Do not scrub hard. Do not twist or wring the foam. Memory foam needs gentle pressure and plenty of drying time.
Viscosoft's insight
A small stain does not need a full wash. Spot cleaning is often the better choice because it limits water exposure and helps the pillow keep its shape.
Can you hand wash a memory foam pillow?
If you are asking can you hand wash a memory foam pillow, the answer is sometimes yes, but only with care. Hand washing is safer than machine washing because you control the pressure and movement.
Use this method only when spot cleaning is not enough and the care label does not warn against it:
- Fill a clean tub or basin with cool or lukewarm water.
- Add a small amount of mild detergent.
- Submerge the pillow only if the care label allows it.
- Gently press the foam so the soapy water moves through it.
- Drain the water and rinse with clean water.
- Press out extra water with towels. Do not twist the foam.
- Air dry completely in a well-ventilated area.
Hand washing can take a long time because memory foam holds moisture. Do not put the pillow back in a cover or pillowcase until it is fully dry.
Can you wash shredded memory foam pillows?
If you are wondering can you wash shredded memory foam pillows, the safest answer is to check the care label and clean carefully. Shredded memory foam pillows are not all built the same way.
Some have removable covers. Some have an inner liner that holds the fill. Some allow adjustment by removing foam. Because of those differences, it is risky to assume that the whole pillow can go into water or a washer.
For most shredded memory foam pillows, wash the pillowcase and outer cover first. If the foam itself needs cleaning, spot clean the affected area and let it dry fully. Avoid washing loose foam fill unless the manufacturer clearly says it is safe.
What to do if your memory foam pillow smells
Odor can come from normal use, trapped moisture, sweat, or a new pillow airing out after packaging. Start by removing the pillowcase and cover. Let the foam air out in a dry, well-ventilated room.
For older odors, sprinkle baking soda over the pillow and let it sit for at least one hour. Then vacuum it gently with an upholstery attachment. Repeat on the other side if needed.
If the smell comes from a new pillow, give it time to air out before use. New foam smell usually fades with ventilation.
How to dry a memory foam pillow safely
Drying is one of the most important parts of cleaning memory foam. A pillow that feels dry on the outside may still hold moisture inside.
Place the pillow in a room with strong airflow, or set it outside in a shaded, dry area when the weather allows. Flip it a few times while it dries so both sides get air.
Do not put memory foam in the dryer unless the care label clearly says it is safe. Avoid direct high heat from a hair dryer, heater, or radiator. Heat can damage the foam and change the shape of the pillow.
How often to wash the pillowcase and cover
The pillowcase should be washed often because it collects sweat, hair products, skin oils, and dust. A good rule is to wash it when you wash your sheets.
The removable pillow cover should be washed according to the care label. Some covers can be machine washed, while others need more careful handling. If your cover has cooling fabric or special construction, avoid high heat unless the label says it is safe.

Protecting the rest of your sleep setup
Pillow care is only one part of keeping your bed clean. Your mattress and topper also collect daily moisture, sweat, and dust over time. A washable protector can make the larger parts of your bed easier to maintain.
If you want to protect your mattress or topper from spills and daily wear, explore ViscoSoft mattress protectors.
When to replace a memory foam pillow
Cleaning can help with stains and odor, but it cannot fix a pillow that has lost support. If the foam no longer returns to shape, feels lumpy, stays damp, or no longer supports your head and neck, replacement may be the better option.
Common signs it may be time to replace your pillow include:
- the pillow stays flat after use
- the foam has cracks or weak spots
- odor returns soon after cleaning
- you wake up with new neck or shoulder discomfort
- the pillow feels uneven from side to side
If you are ready to compare new options, start with the ViscoSoft pillows collection. The Classic Pillow is one option to review if you want a familiar memory foam feel.
Choosing a pillow that is easier to maintain
When buying a new pillow, look beyond the feel. Care matters too. A removable cover can make cleaning easier because you can wash the fabric layer more often while protecting the foam inside.
If you want more control over pillow height and feel, compare the Signature Adjustable Pillow. If cooling is a main concern, compare the Cold Wire Plus Pillow.
Final takeaway
Memory foam pillows can be cleaned, but they need gentle care. Wash the pillowcase often, clean the removable cover according to the care label, and avoid putting the foam core in the washer unless the brand clearly says it is safe.
For most stains, spot cleaning is the best first step. For deeper cleaning, careful hand washing may work if the care label allows it. The most important rule is to let the pillow dry fully before using it again.
