Nothing works..

Hi!!!
my name's Rain, and i recently found an ipod touch on the beach, i was so stoked!! i pressed down the power button and it said that it was out of battery so i thought, yea ok, it still works, it just needs a charge. No water damage was done to it, it just needed a clean out. Anyway, after cleaning it out i plugged it into my computer and nothing happened, then it said "device not recognised" so i tried going into itunes and it wasnt there, so ever since it hasnt turned on and nothing has worked, pleeeeaaase help me!!
