I have never experienced anything like it. I would not usually buy used bedding but money is tight and it was good quality and described as barely used. It was meant for DCs bed which really worries me. Is it possible to get rid of the stench and even if I do, would it be safe for a child to sleep in afterwards? I usually buy green products exclusively and I am guessing that this is going to need a lot of non-green intervention and some more.
