I made laundry soap today. I don't think I've blogged about that here.
One to one and a half cups grated (non-moisurizing) bar soap (any kind)
One cup Borax or other powdered boric acid
One cup baking soda
Use one to two heaping tablespoons per load, depending on water level. I hope to make our own bar soap soon too and be completely old skool.
