One way is to use commercially available chemical solution (any automotive parts/supplies shop) called Naval Jelly. I have used this to remove superficial rust from car sheet metal prior to repainting. There is an interesting electrolysis method, described at the following site http://www.bhi.co.uk/hints/rust.htm Rainer Blomberg -----Original Message----- From: Earl Moon [mailto:[log in to unmask]] Sent: Monday, December 03, 2001 6:31 PM To: [log in to unmask] Subject: [TN] Rust Removal 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?
