My friend gave me some of her old prefolds and they REEK of bleach. Not only this, but I used them on my DS (after washing two different times in hot with borax and two hot rinses) and he got a horrible blistery rash that took two weeks to go away. I'm not sure what kind of detergent she uses, so that combined with the bleach seems to be a really bad thing for DS's skin. Is there anything I can do to get all of this crap out of the diapers?
