Why not rice? because rice removes the moisture inadequately and temporarily. There are chemicals in water tap water and especially in soapy water. Chemicals left behind may absorb moisture from the air and continue to corrode the metals inside. If the device is not properly cleaned, it will eventually fail! Even alcohol is not entirely safe because alcohol usually contains a small amount of water and will absorb more from the air. Nail polish remover and acetone should not be used on plastic items because they are very strong plastic solvents and may dissolve protective coatings and weaken plastics inside the device. Get a professional to disassemble and thoroughly clean and dry otherwise because the device may fail unexpectedly and permanently even years later. This happened to a close friend who didn't backup her device. Avoid tragedy! Back up your device frequently!
