Any recipe using grated soap is going to leave residue on your dipes, especially if you are using dipes made of synthetic materials. Some people on here stated that cotton dipes would work ok with a homemade detergent, but I didn't have a great experience with it. Homemade recipes aren't harsh, they just don't rinse that well due to the soap. In fact, after I stopped using it, I could always tell when I washed something that had previously been washed in the homemade stuff as the wash water would have lots of floating soap residue in it.
I read on here that a recipe using equal parts washing soda, Borax and an oxygen cleaner was ok for dipes, and I used it a couple of times but didn't find it to clean as well as I would have liked.
