One possible way to dry an electronic device is to submerge it in rice overnight with the device off. The rice will absorb the moisture that may have penetrated the device, but could leave dust in and around the device which could cause overheating. One safer alternative is to use an electronic drying system such as the Save a Phone Rescue System. The device is placed in the bag which contains materials that will absorb moisture from the device but will not contaminate the device.
