Choosing a detergent to wash your cloth diapers in can become a daunting task, even though it doesn't seem like it would. You know that you want something scent-free & dye-free, but that's where the confusion begins! Here is a fantastic website that lists HE & regular detergents: http://pinstripesandpolkadots.com/detergentchoicesataglancepspd.htm
In general, this is a great site to refer back to.
***I've said it before & I'll say it again- I LOVE unscented Crunchy Clean that can be found on Etsy.com. It is all homemade & lasts a super long time.
