De-rusting some stuff

Well, they say the stronger you make the mixture and the higher the amperage, the faster. I will let you know how this turns out. I basically posted this thread when I started so I have a timer! The last stuff I did, quite a while ago, took many hours. But I don't think i ran anything to strong back then. I beefed it up pretty good this time. :)
It is not supposed to do any damage whatsoever no matter what. Once the rust is gone, the reaction ends.
