That's weird... I've always read about not using diaper rash creams, but I used Boudreaux's Butt Paste with my son and cloth diapers and never had a problem. Maybe it's brand-dependent.
Anyway, I agree with the pp - wash/scrub your pockets with Dawn. You can also wash your inserts with a squirt of Dawn and a very hot wash. If you want to get really crazy you could boil (like in a big pot on the stove) your inserts and that will get EVERYTHING out. Have you pinpointed whether the problem is with your pockets or your inserts? (Try some different inserts - even some prefolds - in your pockets and see whether that works to do this).
