For sewing cloth diapers, I often need to strip the fabric just like I would strip stinky diapers. Wash on extra hot with a little Dawn, then rinse (I use hot!) until there are no more suds when it's agitating. I got some microfleece I had to do this on because it was repelling rather than wicking.
