How to Wash Foam Pillows in a Washing Machine?

Foam pillows are a favourite for comfort and support. Like any bedding, they pick up oils, sweat and dirt over time, so they need regular cleaning. Machine washing them is usually fine if you take a few precautions, and the label has the final say. Foam absorbs water like a sponge, tears under rough agitation, and can grow mould deep inside if it stays damp, so the method matters.

Here’s a step-by-step guide to washing foam pillows in a washing machine, from Pain Free Aussies

 

Prepare the Pillows

Check the care label first. Some foam pillows should only be spot cleaned. Solid foam (one block) usually needs hand washing, while shredded foam may handle a gentle front-loader cycle. If machine washing is allowed:

• Take off pillowcases and wash them separately if needed.
• Shake off loose debris and dirt.
• Spot clean visible stains with a dab of laundry detergent or stain remover.
• Zip pillows into their covers so the filling doesn’t get soaked.

 

Set Up the Washing Machine

• Use a front-loading machine, which is gentler than a top loader. Top loaders with a centre agitator can tear foam, so avoid them.
• Wash two pillows at most per load, leaving room for movement and water flow. Two together also helps balance the load.
• Choose the delicate or gentle cycle with cold water.
• Add mild detergent, or one made for foam and down, and use less than usual. Skip bleach and softener.

 

Wash and Rinse the Pillows

Once the machine is set, add the pillows. For best results:

• Let the machine agitate for only 1 to 2 minutes, then pause or stop the cycle if your model allows. Long agitation can damage foam.
• Add extra rinse cycles so every trace of detergent is gone, since leftover soap can break down foam and cause odour.
• Take the pillows out promptly afterwards. Don’t leave them sitting wet.

 

Dry the Pillows

Dry foam pillows thoroughly and quickly after washing. This helps discourage mould and mildew.

• Keep foam out of the dryer, since heat can melt foam fillings.
• Squeeze out excess water gently (never wring), then air dry completely before using or storing. Solid foam can take 24 to 48 hours.
• Roll the pillow in a dry towel first to soak up extra moisture.
• Lay pillows flat in a breezy spot and flip them every few hours. Press the centre to check for hidden dampness. Hanging a wet pillow can distort it, so keep it flat.
• Sunlight, when possible, may help reduce microbes, but long direct sun can yellow foam, so keep it brief.
• Fluff pillows now and then as they dry to prevent matting.
• In humid weather or winter, allow extra time and use a fan.

 

Frequency and Cautions

• Wash foam pillows every 3 to 6 months for hygiene, and more often if you sweat heavily.
• Test colourfastness on a hidden spot first, since discolouration can happen.
• Avoid bleach and fabric softener, which can damage foam fillings.
• Wash foam pillows separately from other laundry.
• Replace old pillows that are misshapen or yellowed, since washing can’t restore them.
• Use a pillow protector between washes, and spot clean stains as they appear.

For spot cleaning between washes, blot stains with a damp cloth and diluted detergent rather than rubbing. To freshen without water, sprinkle baking soda, wait 30 minutes, then vacuum it off with an upholstery attachment.

Signs it’s time to replace: it won’t spring back after pressing, it crumbles, or a musty smell lingers after washing and drying.

With a little care, washing foam pillows in the machine is straightforward. Proper drying is key to keeping pillows fresh and in shape, and protective covers may extend their life between washes.

 

FAQ About Washing Foam Pillows

 

Can you put memory foam pillows in the washer?

Yes, but with extra care. Check the tag, use a delicate cycle with minimal detergent, and air dry completely before use. Solid memory foam is often better hand washed.

 

How do you disinfect foam pillows?

Options include washing them, drying them in sunlight, using a pillow-safe disinfectant spray, or spot cleaning with a disinfectant solution. These steps may help lift oils and lower germs.

 

How do you get yellow stains out of foam pillows?

Make a paste of baking soda and water, rub it gently onto the stain, and leave it for a few hours before washing. For stubborn marks, an oxygen-based product may help, but test a hidden spot first.

 

Can you put foam pillows in the dryer?

It’s best to air dry. Dryer heat can melt the foam fill and cause shrinking or misshapen pillows, so dry them flat instead.

 

How often should you wash foam pillows?

Every 3 to 6 months suits most people, and more often if you sweat a lot at night or live somewhere hot and humid. Spot clean whenever stains or odours appear.

 

What detergent is safe for foam pillows?

A small amount of mild, low-suds liquid detergent, ideally fragrance-free. Skip bleach, softener, and strong stain removers, since foam holds onto soap and it’s hard to rinse out.

 

How long does a foam pillow take to dry?

Solid foam can take 24 to 48 hours to dry fully, and shredded foam usually less. Flip it regularly and check the centre before you use it.

 

Conclusion

Washing foam pillows properly is simple and keeps them fresh and comfortable for sleep. With basic preparation, a gentle wash cycle and thorough drying, they can stay clean for years of use. Follow these guidelines to extend their life and save on constant replacements. Washable covers add an extra layer of protection.
