Instructions
Place the PS3 controller onto a flat surface where it will be easy to handle.
Grab the PS3 controller and spray each small crevice around the d-pad where the button sinks into the controller when pressed.
Repeat this for each button that is sticking inside of the controller.
Dampen a cotton swab with rubbing alcohol. Lightly rub each button with the alcohol without letting any of the liquid to drip into the controller.
Allow the controller to dry upside down, so any liquid that may have entered the controller is drained and completely dried.
