How to clean oxidized game cartridge pins

This video shows how you can clean & polish retro video game cartridge pins to make them look and work like new again. This video demonstrates this by using NES games, but the same principle applies to SNES, Sega and Game Boy/Game Boy Color games as well. If you have any older generation game carts and you cannot get them to work and you have already checked for damage and you cannot find any, its likely dirty/oxidized pins on the game itself. Especially if you know you have a working console.

NOTE: I say corrosion in the video when I mean to say oxidation. My apologies. The games in this video do not have corrosion on the pins, they have oxidation.
