Did you know, Martha Stewart recommends that all pillows be cleaned every three to six months to remove mold, bacteria, and odors?
The first step to cleaning all pillows is to check the tag. Some pillows require special care or dry cleaning only. If you are able to launder your pillows at home, set your washer to the gentle cycle. Use a small amount of mild liquid detergent. Loosely and evenly fill your washer with pillows. Do not over-pack your washer! Run the rinse cycle twice. Some pillows will be able to be transferred to the dryer. If you pillows cannot, hang them from a rack or clothesline.
Try to avoid using powder detergent if possible. This can sometimes leave a residue on your pillows. This method seems to be better if your pillows have been laundered regularly. If the pillows have been neglected a little longer than they should have, some people recommend using very hot water, 1 cup of detergent, 1 cup of bleach, and 1/2 cup of Borax. This is a much stronger method than I have ever used. If you'd like to read more about this method, visit the blog One Good Thing. They have a really great before & after photo.
This definitely isn't the toughest chore, but sometimes its just easier to start small. Think of this as the warm up lap for your spring clean marathon! Have fun!
