how to clean pillows (I definitely don't do this as often as I should.) *EDIT: Washed two feather pillows with detergent, baking soda, and vinegar. These pillows are old and smell like head sweat (ew, I know) and a bit yellowed. They're finishing up in the dryer now and while not like new, they're fluffy and smell pretty damn good. 100x better than they did, anyway!! So. Adi approved.
