I spent 1 month with my whole mission being to fall in love with Rockin Green Laundry Soap. I bought a big bag of the grape soda (yum! I have a love of Fanta Grape so that is why I chose that scent).
pre-month: I stripped all diapers so I could start fresh. (with RG) I followed the instructions on the card that the soap came with.
week 1: I soaked all my diaper loads of no more than 10 diapers in 3 Tbsp of RG and scalding hot water mixed with boiled from stove top and hot from the tap. I did this because I was told by many that the reason the first time I tried RG was because I didn't have hot water to my washer and it requires hot to activate. Well, all week I activated that crap and still, the diapers smelled like crap. Oh, so I did the soak with detergent, then wash then 2 rinse cycles.
week 2: Maybe I need a smaller wash cycle. So I did 120 degree water with 6-8 diapers and repeated wash routine from week 1. result" crappy smelling diapers.
week 3: the way to get hot water out to my laundry room became a serious pain in the ass. So I returned to my cold water and put in 8 Tbsp. of RG. Well the diapers didn't smell crappy anymore but they did still have a dingy look to them.
week 4: went out and bought Tide regular because I ran out of RG and voila! my diapers were clean, white and fluffy.
