Trick i learned a while back that i have used on cell phone, keybored, and believe it or not a old laptop i had is to make sure the item has no battery in it and no power supply put the bath water on very hot and dunk the item into it and keep moving it around until it cleans out everything when your done get a air tight container can be tuperware, ziplock bag, anything that can fit the item before putting the item in you have to make sure to use air compressor or something to clean out as much water as you can, then put dry rice into the container the stuff that is completely dry that comes in the big bags then put the item in there ans seal it and put it into a warm room. While its in the room the water will start to turn into moisture but instead of it collecting above on the lid (condensation) the dry rice will absorb the water and in 24 hours you will have no water in the item at all.
