Reddit reviews Laundry: The Home Comforts Book of Caring for Clothes and Linens

It's called Laundry. It goes into significantly more detail than you need to get started (if you go to a laundromat and don't know what you're doing, you can literally just ask the person next to you and they'll show you where to put the detergent and how to turn the thing on), but it has useful info that I doubt any of my more recent ancestors knew.
