Allen's Naturally Detergent (946mL)Product Rating: Product Review (submitted on October 13, 2011):
We've been using Allen's for over a month now with our cloth diapers. Even with (almost) daily washes, Allen's doesn't build up, rinses out well and therefore hasn't caused any repelling. We used other diapering-specific detergents but had build-up and stinkies issues, so I highly recommend Allens. As noted previously, it's also very, very cost-efficient as you only have to use a small amount. I use a little over 1/2 an ounce for one load of diapers. Worth a try!!
