Instructions
Dilute the rubbing alcohol in the water. Mix together 1 tablespoon of rubbing alcohol with 1 tablespoon of water.
Dip the very tip of the cotton swab into the alcohol and water mixture. Do not dip the entire swab. You want just a small amount of liquid on the tip of the cotton swab.
Rub the tip of the cotton swab around a button and inside the cracks. The tip will not go far into the cracks. Do not force it.
Repeat Step 3 with each button, the D-pad and the analog sticks. Dip the tip of the cotton swab into the liquid again when it becomes dry.
Wipe down the entire controller with the lint-free cloth.
Set the controller somewhere out of the way, with the analog sticks facing up. Leave it to dry for 12 hours or more. It must be completely dry before using.
