I think this is the second thing I have read regarding citric acid and hard water. I am going to try to find it. The other article was to buff it on a surface and then pour hot water on it. It did seem to get the hard water off of the stainless steel. Since we are not allowed to have phosphates anymore my dishes look horrid. I am going to find the stuff and give it a try. Thanks for the great idea.
