:yeahthat:. Napisan isn't good for elastic or PUL, and probably won't do the minky any favours either. It could also leave a bit of residue build-up which will make your nappies less absorbent, too.

It may not kill your nappies if you use it just once, but they really won't love you for it. If you leave any stained ones hanging either outside or near a window, even the UV on a cloudy day will help. I don't know about frost because we don't get it up here (lol), but stains will fade over time even with minimal UV exposure.

Bleach and other chemicals can be used on flat nappies because there's no elastic or PUL to ruin, but are unnecessary and can be irritating to bubs' skin anyway. I think that a lot of the old perception that cloth caused nappy rash came from using harsh chemicals to soak the nappies. And there was much less understanding of the environmental impact of bleaches and chemicals, so they were seen as something desirable. This was also partly due to marketing, cleaning chemical manufacturers didn't want people to use common and inexpensive household products like bi-carb and vinegar that they'd been using for generations.
