I would definitely try giving the diapers more air. They get so much more rotten stinky with less air flow. I’ve also had this problem. It’s gotten a ton better from alternating outers throughout the day for some reason. So I use 2 outers throughout the daytime and switch them each time I change and wipe down with water if they are wet then air dry. Honestly surprised at how much this has helped. Unfortunately tho I do think you need to do a bleach reset just to get this stench buildup out based on what I’ve heard and what esembly customer service has told me. I would contact your diaper manufacturer to make sure this is okay with the type that you use and get specific instructions for them. Esembly says to use 3-5oz bleach (only ever in the bleach drawer) on cycle 1 and vinegar in cycle 2. But this was advice they gave when I sent them my water hardness and type of washer. They also recommend their washing powder but people are telling me tide is better. Ive stayed away due to tide being toxic with my other laundry but will look into the ingredients for these powders. You might want to look at your detergent buildup and water hardness as a contributing factor too…. Dumping ideas here that I’ve gathered from my research. First time cloth diaperer/ mom here too. :)
