Things You'll Need
Instructions
Unplug the controller from your GameCube game console.
Dip the edge of the toothbrush's bristles into a cup of warm water. Make sure the toothbrush is clean, the water is not too hot and the toothbrush has a minimal amount of water on it.
Scrub around the edges of the buttons, control stick and joystick using the toothbrush.
Absorb the water on the controller with the paper towel. Press deeply around the edges of the buttons so that all excess water is absorbed.
Place the controller in a safe area for around six hours, allowing the controller plenty of time to dry. Plug the controller back into the GameCube and start a game to test it.
