Okay I had some absorbancy issues and I stripped and added some filler and it seemed to help. I noticed a faint "old" (like, old barn) smell after stripping when the diapers were peed on, but that went away after the next wash, so I didn't worry about it. They smelled perfect coming out of dryer. Fast forward to today, I washed diaper yesterday, ALL of them. Stuff ALL my pockets (I hate stuffing pockets, I am not buying another pocket diaper as long as I live. I prefer using prefolds and covers to stuffing pockets!!). Put a diaper on him and put him to bed. When I woke for 2 am feed, it was so smelly. No ammonia smell, just a icky "old barn" smell. Okay, that was one diaper....put another one on him. Same smell, only I swear worse. I think it is just the microfiber ones, I have not noticed an issue with my prefolds. So from what I have read, this means I am probably not using enough detergent (or the right detergent) and they are not getting fully clean in the wash. So quick question (if anyone replies before I go start the next load...), I don't know whether to wash them again with extra detergent like normal, or use Dawn and just wash/strip them again? I also added vinegar to my prewash and will use it in the rinse. Charlie Banana (the brand of the pocket diapers) recommend using it for smell so I will not void my warranty or anything (although I may have already with the HOT wash instead of warm...) and I don't think it will hurt them. That may help with the smell as well.
