How to Wash Pillows in the Washing Machine Without Damaging Them

You wash your pillowcases every week. But what about the pillows underneath? Most of us don’t give them much thought. After all, if there’s a pillowcase covering them, why wash the actual pillow?

But after months of sleeping on it, sweat, body oils, drool, and dust can work their way through the case and into the pillow itself.

Luckily, there’s an easy fix. Despite what most of us think, you can wash pillows too - and in many cases, you can wash them in the washing machine! You just need to learn how to wash pillows in the washing machine the right way and remember a few things before getting started.

Can you wash pillows in the washing machine?

Usually, synthetic or down-filled pillows can be cleaned in the washing machine (provided you use a gentle cycle and gentle detergent). However, some other types of pillows don’t do well with a machine wash. 

Pillows made with dense memory foam and delicate feathers shouldn’t be machine washed, as their filling can easily break apart due to the excess agitation or retain water, resulting in damage.  

Here’s a simple guide to help you understand which types of pillows are generally machine washable:

Even when a type of pillow is usually machine washable, don't skip the label. The outer fabric, construction, and filling can change the manufacturer's recommended care. 

How to wash pillows in the washing machine without ruining them

Here’s a simple step-by-step guide on how to wash pillows in the washing machine without damaging their filling:

Step 1: Read the care label

Some pillows can withstand machine washing, while others need hand washing or dry cleaning. Read the care label on your pillows carefully to find out what they need before tossing them into the washer.

The label will also tell you about the water temperature and drying requirements, so you won’t need to guess stuff once you get started.

Step 2: Prepare the pillow & spot-treat stains

Remove the pillowcase and any removable protector. These can usually be washed separately with your sheets.  

See a yellow sweat mark, makeup, or another stain? Treat it before the pillow goes into the machine, following the care instructions for the fabric. You can use a gentle enzyme-based stain treater like the Mozi Wash Stain Treater to gently lift the stain without damaging the pillow.

Step 3: Place the pillows into the washer

If your washer has enough room, washing two pillows together can help keep the load balanced.

Don't squeeze several pillows into a drum just to get them done in one go. They need enough room for water and detergent to move through the filling.

Step 4: Add a gentle detergent

Avoid using strong detergents with harsh chemicals and surfactants. Instead, use a gentle one like Mozi Wash to gently clean the pillow without having harsh chemicals soaked up into the filling.

Step 5: Select the gentle cycle

Follow the care label for the correct water temperature and cycle. For pillows that allow it, a gentle cycle can help limit unnecessary stress on the filling and seams.

Once the wash finishes, make sure the detergent has rinsed away properly. If your pillow's care instructions allow it, an extra rinse can help remove anything left inside the filling.

Machine washing vs. hand washing pillows

While it helps to know how to wash pillows in the washing machine, it’s not the only way to have clean pillows. You can even handwash your pillows. 

Let’s see how the two methods compare so you know exactly which one to choose:

How to dry pillows without damaging their filing

To understand how to clean pillows in the washing machine properly, you also need to learn how to dry them the correct way to avoid damage. Half-dry pillows can become breeding grounds for mold and mildew, while excess dryer heat can melt synthetic materials and ruin feather materials.

So how do you do it the right way? Just follow these tips for pillows that are dryer-safe:

• Check the care label for the correct dryer setting and temperature.

• Use low or appropriate heat rather than automatically choosing the hottest setting.

• Fluff the pillow periodically to redistribute the filling and break up clumps.

• Add 100% New Zealand wool dryer balls from Mozi Wash to help keep the filling moving as the pillow tumbles.

• Check the center carefully before putting the pillowcase back on. Any remaining dampness means it needs more drying time.

If the pillow isn't dryer-safe, follow its air-drying instructions. Give it plenty of airflow, turn or reposition it as needed, and don't put it back on your bed until the filling is completely dry. 

Keep your pillows soft and fluffy with Mozi Wash

When learning how to wash pillows in the washing machine, a big question is which detergent to use. The best detergent for pillows is one that is gentle, yet effective - just like Mozi Wash laundry detergent. 

Mozi Wash detergents bring you the best results with a:

• A low-sudsing, concentrated formula that rinses clean.

• Plant-based enzymes to tackle everyday buildup.

• Long-lasting fragrance, so there’s no need to add fabric softener just for scent.

Your pillow wash day made simple

You don’t need to replace a pillow just because it looks a little dirty. If the care label allows it, you can easily wash your pillows in the washing machine.

Just remember to:

• Check the care label

• Use a gentle cycle

• Add a gentle detergent like Mozi Wash

• Thoroughly dry the pillow before using

If you get these basics right, understanding how to wash pillows in the washing machine becomes super simple. 

How to wash pillows in the washing machine FAQs

1. How often should I wash pillows?

Generally, it’s good to wash your pillows every 3 to 6 months. However, it all depends on the manufacturer's instructions and your usage. For instance, if you’re a sweaty sleeper, you may consider washing pillows more frequently.

2. Can I wash all types of pillows in the washing machine?

No. Many polyester, down, and feather pillows can be machine washed, but memory foam and latex generally shouldn't be. Always check the individual pillow's care label before washing. 

3. How to wash a feather pillow in the washing machine?

First, make sure the care label permits machine washing and check the pillow for tears. Use a gentle cycle with a gentle liquid detergent and cool water to wash the pillow. Rinse it thoroughly, and make sure the feathers dry completely before you use it. 

4. How to wash and dry memory foam pillows?

Memory foam generally shouldn't go in the washing machine or dryer because agitation and heat can damage the foam. Follow the manufacturer's instructions, which may call for spot cleaning or gentle hand cleaning instead.

5. How to remove stains from pillows?

You need to spot-treat stains with a gentle stain remover. Just apply the recommended amount on the stain spot and let it sit for 10-15 minutes. You may gently rub it to lift the stain and then wipe the spot clean.
