How to Fix Sound in Electronics That Fell in Water

Almost a year ago, water fell into my ipod and the sound wasn't working anymore.. i could hear sounds when i plug my earphones, but i can't hear anything without them !!
later then, my aunt told me to put my ipod in rice for a couple of days.. i didn't think it would work since many people pay $20-30 to have the sound on their devices fixed, but i thought that i should give it a try ! and guess what? it worked.. it actually worked ! later that year, my best friend's brother's ipod fell in water and it wasn't working plus the screen broke.. the rice method that i told her about worked and all her brother had to do was replace the screen which was a lot cheaper than replacing the whole ipod ! so that means that the rice absorbs the moisture and it fixed both the sound or the ipod..
ps: this doesn't only work with ipods it also works with phones...
pss: if this method doesn't work you will have to take it to an electronics store and they'll fix it for ya !
