I think they sat too long in a wet pail - to my shame - with one holding a poo explosion. I'd rinsed it but - now i have about ten nappies that just.. ugh..
Also, DH has put them through the dryer a few times - could this have 'baked in' the stink?
We usually wash them with soap nuts, I've tried using a 'proper detergent' in case that would work. Does anyone have any tips? Desperate here!
