I was not paid to say this, but for cloth diapers, I love All Free & Clear! It's cheap and it does a great job. I have never once had to strip my diapers due to detergent build-up, I've never had an issue with diaper odor, and I've been using the same dipes for 18 months! At first we started with Charlie's soap laundry powder, but I just decided it was too expensive and on the advice of another CDing friend, Aletta, decided to switch to All F&C about a year ago.
So to those new CDing mamas, don't let the interwebs convince you you have to buy special, fancy, expensive soap to safely wash your diapers. All Free & Clear will do the job just as well.
