Blue dawn strip? Bleach? Vinegar? It's mainly an issue with my nighttime diapers which are a variety of fitteds and some organic flip inserts.

I switched from a natural detergent to Tide original and it got rid of all my "poo" stink. My diapers were always clean LOOKING, but when I smelled my BG pockets, they smelled like poo.
I really hot soak and bleach, then started washing in tide.
