Smelly Diapers

April.
I am new to cloth diapers, so I'm in desperate need of some advice. 
I've been using pocket diapers for about a month now and when my baby pees in them, they have a strong odor. I wash the inserts separately from the covers and wash them on a cold cycle and warm cycle. I bought some Charlie's Soap and started using that during the cold cycle, but that didn't help. I hang dry the covers and use the dryer for inserts. How do I fix my smelly diapers?
