I am looking for good guidance in preserving brass and copper on 1800s steam locomotives. I am worried because the brass is in excellent condition and I don't want to damage it. Current procedure uses an industrial cleaner, but I wonder if it is stripping the brass away. Thank you John Hunter Curator Kennesaw Civil War Museum "Home of the General" _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
