In an earlier thread I asked for suggestions on how to remove rust from some cast iron cooking ware. Most suggestions involved filling a large bucket with vinegar and hooking the iron to a battery. I then remembered that years ago I had used muriatic acid to remove rust from tools. I bought two gallons of the acid from Home Depot for seven dollars and gave it a try. While the acid is not as strong as it used to be it still does a good job. Tomorrow I plan on giving it a good scrubbing with one of my wife's pot scrubbers. I am attaching before and after pictures to show the difference. I don't know if they are clean enough to cook with but with a good scrubbing I can't see why not. After all people swim around in the stuff. Of course in a swimming pool it is diluted considerably.
