We were using charlie's soap, but I think that may have been what was causing some of the rashes for my older son, so we switched to allen's naturally. I like it alot so far, but I've only used it a couple of times. I like that it takes so little to clean. I used two teaspoons in the first load of diapers and it took me three full cycles of no detergent to rinse it out (i.e. no bubbles in the rinse). So the next one I only used one teaspoon and it worked fine.

At that rate, my gallon is going to last forever.

Happy me.
