I'm using Bumgenius freetime nappies, they're a aio nappy, only been using them a month and they have a wee-ish smell about them.
I dry pail, do a cold rinse before washing at 40 degrees, use 1/4 of powder as recommended on the nappy instructions, I can't wash any hotter as 40 is the hottest temp recommended. I wash every third day and line dry whenever possible.
Thanks for any advice you can offer
