Folks, We had a lively answer session last month. One of you gave very insightful answers about the differences between oxidation, rust, and the like. I do have a serious question about the best ways and chemistries required to remove rust. What is the best way and or chemical solution to remove rust, say, on cold rolled steel or iron? Can I use an acid solution and, if so, what would it be?
