I read this in Lucky a few days ago and am excited to try it. Right now I clean my dainties with the rest of my laundry because my apartment feels too small to do anything else. All you do is get a glass jar with a lid like these from the container store, some nice delicate wash detergent, and then fill the glass jar up with warm water add detergent and shake. Apparently this is the way the lingerie designers do it.
