I bought a metal diaper pail (Ubbi!) for the nursery but since baby will be in our room temporarily, we got a very cheap one secondhand in great condition. It's very clean and works well, but since it's plastic.... it's still holding on to that delightful diaper stank. I cleaned it with 409 and threw some dryer sheets in there for a week, but it's the same. Any tips? Or do I just have to deal with it?
