Re: Laundry Soap
We use All Free and Clear for diapers and everything else and have never had issues with stink. I fill the cup to the 2 line for all full loads. I usually throw a few towels in with the diapers unless I'm washing a big diaper load because otherwise they don't seem to get agitated enough (we have a Samsung HE front-loader that's a couple years old).
One thing I have noticed is there is slight staining that is apparent. I've been without a clothesline for the last four months (oh how I miss it!) so I haven't had a decent place to sun my diapers. The only CD detergent I've ever tried was Rockin' Green for hard water and it never got my diapers totally clean.
