Dear Aasheesh,

Your questions are simple requiring answers which may fill textbooks!

I do bright dipping of Carbon brush holders which are like the parts you describe. use any of the innumerable solutions available in the market or try the Canning Handbook recipes. Daulat in Bombay has good products also.

Re. rust treatment of Iron, please be more specific.
