Hello all, this isn’t exactly a machining question but since I go to you guys with those questions I figure maybe there’s a chemist or two in here. Ok, so I’m building an automatic transmission that has sat out in the elements for a while and I have some internal drums and things that have a fair bit of rust on them, but not in any critical areas. I have been thinking about ways to remove the rust and it seems a dip in some ospho blue has worked in the past however I will need a way to effectively neutralize the acids once removed from the bath. Getting mixed information on the web. My thoughts were use a bath of mineral spirits followed by an oil bath. Trying not to use water since that will pretty much undo what I just did. Would love a little guidance or at least some different opinions. Thanks in advance
