Thanks Mike and Denis, I don't have any thinking ability this AM and didn't think this subject too big an issue but for me. Think the spoon in ear stirred grey matter too much. I like sand blasting but for the sand but acid ain't too cool either. Now, if Dremel made a miniature sand blasting tool, that would be cool. Forgot to ask about neutralization when using acids. Is a water rinse sufficient or must an over 7 ph chemistry be used to do the job? I know this is a loaded question as well but it must be simple. I've used the Naval Jelly before and the rinse did the trick. The stuff I'm derusting is a bit more sensitive and needs as near original surface as possible - with minimal damage. Some of the surfaces are mildly rusted and others ar a bit more damaged.
