If you have a PlayStation 4 and your controller has started to show signs of water damage, there are a few things you can do to help. First, make sure that the controller is completely dry. If it isn’t, you can try cleaning it with a mild soap and water solution. If that doesn’t work, then you may need to replace the controller. Second, if the controller is still wet, try using a hairdryer on high heat to dry it off. Finally, if all of these methods don’t work or the controller still looks like it’s in bad shape, you may need to take it in for repair.
