I know it's been discussed here before, but I don't believe this question ever came up.
I plan to try using reverse electrolysis to refurbish some old tools. I have everything needed on hand, so I'm happy just experimenting a bit, but I was wondering: does existing iron in the water make a difference? Here on the farm, our well water is quite rusty - visibly reddish in large enough quantities, and tasting vaguely of blood. (It's been tested, and is perfectly safe to drink. No anemia for us!)
My gut feeling is that it shouldn't have much of an effect, or that I can compensate with more sacrificial material and/or more time in the bath if it does, but I'd like to know if anybody here has any thoughts on the matter. (Worst-case scenario, I can run a hose out from the house - it's softened in there.)
