Pour coke (has to be coke, not pepsi) on it until it stops fizzing.... Baking Soda and water will work too.

Just seen your post. Try coke on a q-tip or baking soda and water. DI water to rinse up and isoprophoalcohol to clean up. Make sure to use ISO, regular alcohol will leave a film.

inside electronics best i ve been able to do is sand off until shiny, without going destroying the contact,
 
Coke and baking soda were my first choices. In an electronic device, scrape off what you can and then use Q-tips or a make-up sponge applicator. Not too wet. You don't want that running where it shouldn't be. Rinse with clear water(same method) Dry well before using.
Perhaps a little De-Ox could be used on the now clean contacts.

Hope this helps.
 
Go to Home Depot or Raido Shack and get a spray can of contact cleaner. This is the product we used on multi-million dollar machines in the paper industry. It is safe to use, drys instantly, and is non conductive. Coke is an excellent rust remover, but I wouldn't recomend it for electronic devices. If you don't get it completely dry, it could short out your device. If you do use Coke, blow it out with compressed air to remove any moisture. You can also clean your contacts with emery cloth or sandpaper. Again blow out particals with comperssed air. Jim S
 
I use to fix copiers and never used liquid. Contact cleaner is good, but if it is a small device I would use a good full size pencil with a clean eraser. The eraser can be used to clean off and scrub the contacts. There is no liquid to get in the wrong place and then I would blow it out with canned air that is used to clean key boards and other electronics to make sure you get all of the bits out.
