How do I put the 'fresh' back in nappies

[chubbleigh]

Is there an absolute cert for getting nappies smelling fresh again. I have some Fuzzybuns nappies that I want to sell on but they have got a very slight whiff about them, they are perfectly clean and not stained but are not completely odour neutral if you know what I mean. Once used can they ever smell new again. What is your sure fire dead cert cleaning solution?

Do you use non-bio? I used to, but my nappies were a bit whiffy. I now use biological powder (Daz is quite good, if a bit common ahem) and hanging them on the line outside might make them a bit fresher too?

Bio powder with a bit of vinegar in the rinse, then rinse, rinse, rinse. Most wiffs are caused by detergent build up in the nappy. Alway give a cold rinse before you wash so you dont get the 'cooked' in wee affect
