|I used 4-5 nuts, and I used them 3 times. They first two were good, the 3rd not quite. But after my 1st set of nuts, I would save all the old ones. after they dried, I'd put them in a thin sock. I would throw the soak in with the 3rd load. Gradually, that sock bag got fuller and fuller, but they did have a bit of soap left in them, so it did help out with every 3rd load.Mama to Rosy-5, Gracie-4, Lizzie-2, Andy-1, and one one the way. My dream is to replace my whole diaper stash with Mother-Ease Diapers!
