Can you please give me some help in natural ways to remove hard water stains from kitchen utensils?

Any mild acid will get rid of scale. Lemon juice, vinegar, even coca cola will do in a pinch. i use vinegar on small items and CLR cleaner on large items. I also clean my dishwasher once a month with CLR. i fill a measuring cup with plain vinegar, soak my things in it for about half an hour and then rinse well.
