Memory foam pillows come in various shapes and sizes, providing excellent neck and head support. However, over time, they can accumulate sweat, saliva, dirt, dead skin, and natural oils from your hair and skin, creating the perfect environment for dust mites and bacteria. Since pillows come into contact with your mouth and nose, keeping them clean is essential for maintaining good hygiene and ensuring they remain in good condition.
You should typically aim to clean your pillows every three months. However, you may need to clean them more frequently if you sweat at night, have allergies, or use hair and skin care products that can transfer onto the pillow.
How to wash memory foam pillows
Memory foam pillows can be sensitive to liquids, so cleaning them requires a gentler approach to avoid damaging the material. Always check the manufacturer’s care instructions to ensure you clean your pillows safely and effectively. A tag or label with specific cleaning instructions is usually sewn onto the pillow. You can also visit the manufacturer’s website or contact them directly for guidance.
Most memory foam pillows are not machine washable because they can quickly deteriorate and lose their shape and support. Memory foam also easily absorbs liquids and can quickly develop mould and mildew if not dried out properly. Furthermore, most memory foam pillows cannot be placed in a dryer as the heat can damage the foam.
Some memory foam pillows have removable covers for cleaning that are usually safe to machine wash with a mild detergent on a cold temperature setting, following the care instructions. Cleaning the covers allows you to keep the sleeping surface clean without handling the foam. It’s best to air dry the covers after washing to avoid damage or shrinkage.
The most effective ways to clean memory foam pillows are by hand-washing or spot cleaning and then allowing the material to fully dry naturally.
Deep cleaning memory foam pillows
- Remove the pillow from its pillowcase or cover.
- Fill a large sink or bathtub with lukewarm water, ensuring the water level is deep enough to submerge the pillow fully.
- Add approximately one tablespoon of mild detergent to the water for each pillow, and then mix the solution thoroughly by hand. Avoid using harsh chemicals or bleach, as these can damage the material.
- Place the pillow in the water, allowing the solution to soak into the material.
- Gently squeeze and massage the pillow with your hands for several minutes to remove dirt and debris.
- Rinse the pillow thoroughly with clean water, applying gentle pressure to avoid damaging or misshaping the foam.
- Once all the excess water has been removed, lay the pillow flat in a well-ventilated area, away from direct heat or sunlight. It may take several hours for the pillow to dry completely. However, you can speed up the drying process by opening doors and windows or using an electric fan to help circulate air. Avoid using the pillow until it is completely dry.
Spot cleaning memory foam pillows
Spot cleaning involves targeting specific stained or marked areas of the pillow.
- Remove the pillow from its pillowcase or cover.
- Mix a small amount of mild detergent with lukewarm water in a bowl, then mix the solution thoroughly by hand.
- Dampen a clean, absorbent cloth with the cleaning solution. Then, gently blot the affected area, starting from the outside of the stain and working towards the middle. Avoid rubbing or scrubbing marks or stains, though, as it can damage the pillow or spread the stain. Use a dry part of the cloth to blot the stain and absorb some of the liquid, then switch to a clean, dry part of the cloth and bloat again. This helps to soak up the liquid without pushing it back into the pillow.
- Use another clean cloth slightly dampened with water to rinse the affected area and remove any residue if necessary.
- Allow the pillow to dry in a well-ventilated room naturally.
Vacuuming memory foam pillows
Gently vacuuming your memory foam pillow with a clean, soft brush attachment helps to remove dust and debris and keeps the surface clean and in good condition.
However, some memory foam pillows are loose-filled, and vacuuming may dislodge the particles, resulting in uncomfortable dips and indentations. If you’re unsure about vacuuming your pillow, check with the manufacturer beforehand.
Can you steam clean memory foam pillows?
Steam cleaning memory foam pillows is not advisable, as the high heat and moisture can damage the material. It’s best to spot clean instead where necessary and allow the pillow to dry thoroughly in a well-ventilated area before use.
Use pillow protectors with your memory foam pillows
Always use pillow protectors with your memory foam pillows to protect them from stains, spillages, allergens, and everyday wear. Pillow protectors come in various materials and slip over your pillows, providing an extra layer of protection. They help keep your pillows fresh, clean, and in good condition.
How to deodorise memory foam pillows
To eliminate lingering odours, sprinkle a thin layer of baking soda over the pillow and let it sit for a few hours to absorb odours. Then, gently vacuum off the powder without damaging the material.
New memory foam pillows can sometimes release a slightly unpleasant smell when unpacked. This is because of the chemicals used during manufacturing, which are trapped in the packaging. The smell is harmless and should dissipate after airing the pillow. There is no need to clean or deodorise the pillow.
How often should you replace memory foam pillows?
It’s generally recommended to replace your pillows every two to four years to ensure they remain comfortable, supportive, and hygienic.
Several signs might indicate your pillows are past their best and need replacing. If your pillows are uncomfortable, lumpy, discoloured, or misshapen, or if your allergies worsen at night, they may need replacing.
Final thoughts
Pillows can affect your sleep quality, so it is essential to wash them regularly. Memory foam pillows require special care when cleaning because the material can easily break down. Avoid placing memory foam pillows in the washing machine or dryer, and always follow the manufacturer’s cleaning instructions.
