I use about a tablespoon of tide, maybe less...I don;t actually measure, and a sprinkling of washing soda (less then an eighth of a cup probably...again I don;t measure) in the cold wash/cold rinse cycle. Then I do a Hot wash/cold rinse with nothing and then usually a warm wash/warm rinse with nothing. I also add an extra rinse to each cycle. We have no stink, no build up and clean diapers and have been doing this method for a long time
