Help my bamboo nappies are turning black! why? dd2 has wicked poop but seriously I never had this problem with dd1's nappies, it looks like they're going mouldy/black staining, wash routine is every other day (so they're not sitting around for ages) cold rinse, 40 deg normal cycle with 30ml powder, then another rinse at the end, hang out to dry on airer for 12-24hrs and 30min low dry tumble to finish them off. It's just my bamboo ones, BBH and BB bamboo inserts, which are her night nappies, don't know if that's the difference that they are worn for 12hrs+ and soaked through with strong wee? in the day I use organic cotton or bamboo/cotton prefolds and don't have a problem with staining on those, but her night nappies are looking horrible! in the summer they were line dried outside and the sunlight would bleach any stains. What do I do? how do you know if you've got the stinkies and need to strip wash as opposed to normal night nappy stink of 12hrs+ of wees?
