I bought a stinky diaper!

[Cdra]

I know there is a thread out there about this but I can't find it.

I bought a used diaper in euc. but it STINKS like ammonia!! I smelled it right out of the bag it shipped in. I washed it with a small load of my regular diapers with bac out in the pre-rinse, extra hot water wash with extra detergent (i use country save) and a squirt of gse, and 2 warm water rinses. It's out of the dryer now and still stinks. I've never had a single stinky diaper. What can i do to rid this one diaper of it's funk??
