Welcome to Brainstuff, a production of I Heart Radio. Hey brain Stuff Lauren Bogle bam here. Although most pillows have a tag giving laundering instructions, not everybody bothers to wash them. We may think they're shielded from the day to day grit and grime of life thanks to the pillow case or else that washing them may ruin them. But the standard pillow case is typically only made of cotton or of some other easily permeated fabric, rendering the pillows susceptible
to the grit and grime of life. But we spoke by email with Mary Marlowe Laverette, a housekeeping and laundry expert with the Spruce. She said, even with a protective pillow case, your pillow can be filled with dust mites, body oils, and bacteria from your saliva. All of that is next to your face and no one wants any of that. And it's no small amount of junk either. After a couple of years, some ted percent of the total weight of your pillow could be due to dead
dust mites and their waste. And yeah, that's kind of gross to think about, but more scientifically speaking, a regular close proximity exposure to Any of these contaminants or others like pet dander can cause conditions like allergies and asthma to flare up. The good news is that laundering pillows is a surprisingly easy task and you don't need to
do it all that often. If you use a zippered pillow protector, you'll only need to wash the pillows twice a year, although the protectors themselves will require monthly laundering. If you don't use a protector every other month ish or whenever the pillow looks or smells like it needs it, is advisable. There could be times when you need to launder your pillows more frequently, but we also spoke by email with Mary Zeitler, consumer scientist with Whirlpool Corporations Institute
of Home Science. She explained if the user applies face lotions before going to bed, or if the user has oily skin or scalp, washing more often may be needed to keep it fresh. We'll add ditto that if you sleep with a pet, or have recently had a cold or other contagious illness, or if the pillow looks or smells musty, So how do you clean your pillow? It's vital to check the care directions on the tag. Many are machine washable, but some, like those made of memory foam,
are not. In general, Zeler recommends washing down feather and synthetic material pillows in the warmest water considered safe for the material, and it can help, especially with top litted washers, to do too per load. To help keep the machine balanced while it's spinning, use a mild liquid detergent, or make sure you dissolve your powder detergent well before adding the load, and set your machine on the gentle cycle. An extra reincycle can help make sure that all the
soap is gone when it's time to dry. Use a low heat or air cycle setting for as long as is an necessary to get all the moisture out of your pillows. Any dampness left behind will encourage mold growth, but foam pillows are sometimes a completely different animal. They can't get excessively wet unless otherwise stated on the care tag, so rather than using a washing machine, you can use a vacuum cleaner to do most of the work, then toss them in the dryer on a no heat cycle
to shake any additional dirt and grime loose. If any spots or other grime are visible, sparingly spot clean with water and a mild soap.
