remove rust from coils in electronic games - old batteries left in game?

I have a v-tech game for my boys. When I was going to play I look in saw that the batteries were corroded..Now the coil in the battery department are rusty. Can that rust be move? If so, with what?

Scrape it off with something sharp or some sand paper in the area where the battery is going to make contact. It doesn't have to be perfectly clean and if you can get the battery to make good contact it will work. If there is still battery acid there it will continue to corrode. You can stop the battery acid with a paste of water and baking soda. Try not to get water inside the game, just where the corrosion is. Next time try to remember to change the batteries before they leak. Good luck.

Well, what has worked for me is putting flux and the a coating of solder, and it cleans it up and improved conductivity.
