A few of my pop-ins and BGv3s are coming out of the wash with greyish mottled stains where they had BF poo on.
They get dry pailed and I wash every day, so they aren't left dirty for long enough for mildew to set in surely? I wash them on a cold rinse cycle first, then a 40 wash with a small amount of non-bio powder. I tried a 60 wash last time to see if that helped but it was no better.
hmm if it's mildew or moudly spots i'd be treating the affected area with a *very* weak bleach solution to kill off any nasties then washing again. but that is fine for whites, but not so good on your colours. are u drying them properly? because i've in the past, thought a nappy was dry but inside the fibres haven't been completely dry. if stored this way it could account for a bit of mildew. in theory.
apparently according to the 'guru's' on here its only the coloured calpol that stains. I use a mixture of everything so i have no idea what is actually causing the stains, but I know when lockie is teething his nappies turn black, and rileys don't (she won't let me give her anything!)
