How To Wash Pillows (and how often)

Having a family of allergy-sufferers, and being one myself, I was delighted by our symptoms’ improvements once I learned how to wash pillows. It’s not just that they smelled better, though that was certainly a nice benefit. Washing our pillows got rid of pollen, dander (both human and pet), and dust mites — three things that wreak havoc on allergies.

It doesn’t seem at first like pillows should collect pollen. After all, they’re covered by pillowcases which you’re changing at least weekly as part of your bedroom cleaning routine. But pollen hitchhikes on hair at bedtime then gets ground through the pillowcase fabric while we sleep. The same goes for pet- and human dander.

As for those dust mites? Those things are tiny — as in 0.2–0.3 millimetres (0.008–0.012 inch) — and they love humid places like warm pillows where they feast on dead skin cells. After that feast they excrete a substance that causes severe allergies in certain individuals.

In fact, over one-third of the weight of a 2-year-old pillow is composed of skin flakes, dust mites and their droppings, and other microorganisms. It can even contain the microbes that cause flu, chicken pox, MRSA, even Clostridium difficile (c. diff).

And we sleep on that stuff!

Fortunately, it’s not difficult to wash pillows to cleanse them of such things. Regular laundering also means they’ll smell fresh and last longer, too. Here’s how.

How To Wash Pillows

You will need:

1 cup laundry detergent
1/2 cup oxygenated bleach (like Oxiclean)*
2 tablespoons Borax
2 tennis balls

* You can replace this with 1/2 cup household bleach, but the scent of bleach irritates many peoples’ allergies and asthma.

1. Fill the machine. Add the detergent, oxygenated bleach, and Borax to the machine then let it fill using HOT water. For non-bleach users, we’re using the water’s heat to kill the dust mites and microbes so it’s very important you use the HOT setting!

2. Add the pillow(s). Carefully submerge the pillows in the water, arranging them so they’re on either side of the washer’s tub. Regular-sized pillows should be washed two at a time to keep the machine in balance. King-sized pillows should be washed individually, unless you have an extra-large washer.

3. Run the cycle. Run the load on the longest cycle your machine has. Be sure to use the HOT rinse cycle, too.

4. Rinse again. Once the cycle has finished, rearrange the pillows in the machine and run a second HOT rinse cycle, without additives, to get rid of any remaining suds.

5. Dry them on hot. Transfer pillows to the dryer. Add the tennis balls to the load to fluff the pillow fibers as they tumble dry. Run the dryer for 60 minutes, pausing every 20 minutes to shake and rearrange the pillows so they dry fully without clumping.

Tips:

• To deal with grimy pillowcases, try these tips.

• Foam-core pillows can’t be washed. To kill dust mites and reduce allergens, spray them lightly with hydrogen peroxide (do not saturate the core) and run them through the dryer for 5 minutes on the high heat setting.

• Washing pillows when the seasons change keeps dust mites under control and reduces the amount of other allergens in your pillows.

• Using a hypoallergenic pillow cover will protect your pillows but you’ll still want to run them through the dryer with tennis balls to fluff them occasionally.
