moto x in sea water

garima, just like any other electronic device that is water damaged, there are a few things that you can try. the major issue you will run into is corrosion damage. Salt Water will get your components to corrode very severely. Remove the battery and dop not try to use/ charge/ connect your phone at all. Then disassemble it by following these guides. Take a careful and close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,.Take a look at all connectors as well as cable ends. After that I would suggest that you clean it a couple of times in sterile water, no drinking water. (that might have helped right after it got submerged in the sale water). Use a soft brush and clean it very, very thoroughly with the sterile water. With the amount of corrosion that I envision, you will most certainly have to remove all the EMI shields. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for a Apple iPhone 3G but it is still pertinent to your phone as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. Do not use drinking water, if you need to use water, use sterile water. Also you do not need to leave it dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. Yes, do replace the battery for sure. Depending on when this happened, I suspect plenty of damage to the pins, that may be irreversible through cleaning. Even with all this, there is really only a small chance that your phone will work, but I definitely would give it a try. Hope this helps, good luck.
