NES Cartridge Cleaning Tools

Or you can find all of these supplies in our Nintendo Cartridge Cleaning Kit

Open NES Cart

Using the 3.8mm Security Bit, unscrew the 3 screws from the back of the cartridge. Our 3.8mm bit is designed to fit in screw holes easily, but this still may require some pressure. Lift up the back side of the cartridge. Be careful not to lose the screws!


With the back open, you can simply pull up the PCB and remove it from the cartridge case


Cleaning NES Gameboard Connectors

The red rectangle highlights the area needing cleaning. Apply the Game Cleaning Paste on one of the Non-Static Cleaning Pads and rub on contacts. You should continue to rub the contacts with cleaning paste until no more black residue comes up. Let dry and wipe it off with some Game Cleaning Rinse. Let dry again. Your contacts should be smooth and shiny. Flip the PCB over and do the other side too!
