I thought calling starsan a waste of money was a bit over the top but no worries, different strokes for different folks. If you create a starsan mixture with distilled water it will stay effective for a long time. It doesn't cost very much as only an ounce of starsan, which is about a dollar's worth, is needed to make 5 gallons of sanitizing solution.
I am curious how you use mr. clean to sanitize. I assume you have to rinse after using it? I know from previously using it that bleach must be rinsed and should not stay in contact with stainless very long to avoid pitting. These are advantages of starsan as it is no rinse and has no usage restrictions that I know of.
He's a troll!
