Liquid damage is a killer for electronics. First thing is to turn off the iPod and remove it from it's power source. Hopefully this will prevent the logic board from getting shorted out. Next, I recommend taking the iPod apart following our guide and letting it dry out for a few days. While the iPod is apart and drying out, you can use some rubbing alcohol and q-tips to try and clean any milk residue you see. The rubbing alcohol evaporates quickly and will not damage the iPod further. Finally, put the iPod back together, cross your fingers, and hope it works.

If that does not fix the problem, then you probably, at minimum, need to replace the logic board. Hope that helps you.

i had same problem with a pool though and yea i just let it dry out and it works for the most part fine now
