How to get rid of the ammonia smell in cloth diapers

If you use or have used cloth diapers then you are familiar with the awful ammonia smell.  Sometimes a simple cold rinse before a regular wash does not completely remove the odor and you end up needing to strip your cloth diapers more or lay them in the sun to dry.  One thing I discovered that really helps get rid of the smell is to add about a cup of vinegar to the cold rinse before you wash your diapers.  If your diapers are really stinky then let them soak for 30-60 minutes in the water and vinegar.  Then wash with cloth diaper friendly detergent and finish with a double rinse.
