I have only ever heard of chelators on this forum. I didn't use one for a few years and the only time I experienced DOS was when a bar or 2 touched some metal. I have about 3 shoe boxes under my bed full of thinner soap slices that are anywhere from 1-3 years old, (I used to save a slice of every batch I made) and no DOS. After reading all of the different posts on here regarding chelators, I do use one now. I do not have any issue with my soaps, but I do not have hard water either. I know many of my family members up north do, and I'm sure some customers do as well. I certainly wouldn't want to turn someone off of handmade soaps due to soap scum.
I have never had anyone even look at my labels...LOL
