Any Suggestions on How to remove oxidation on connector pins. The boards have been sitting for awhile and can't be washed due to transformers and open relays that are on the board.

Alcohol? Crud-cutter?

Cant recommend much without knowing plating(if any).

Can you brush some flux on the connector pins and run them through a heat cycle, hot enough to activate the flux, but not enough for solder to melt or component damage? That should remove most of the oxidation. Then, you can run it through your regular process.
