If they get stinky you may need to strip them, also, you cannot use most rash ointments, if they get on the diaper they prevent it from absorbing. With all cloth diapers, it is best to use a detergent that does not have brightners, softeners, or other additives that coat the diaper and prevent it from absorbing and lock in the stinkiness. I use Planet, many "free and clear" products actually have a lot of junk in them that is bad for diapers, they have a list of them at www.pinstripesandpolkadots.com (I am not affiliated with them).
