To me, hands down use it if you have it, it'll clean faster. I have seen grimey parts, come out of a crock pot on low setting with diluted simple green, looking pretty good. I have never personally worried about using distilled water, either to dilute a solution or to fill the bulk of a tank for a smaller parts container.
