With the bad prefolds, do the hottest, longest, most heavy-duty wash you can do, with bleach. There's bacteria in there causing the ammonia. You might need to do something similar to your diapers that are now also smelly, but I'd say you can be a little less intense with it if you think your diapers aren't up for it. But with prefolds, you can be pretty much as harsh as you want and not worry because there's no PUL material.
