phone dropped in sea water

Whilst on holiday last week I had my personal mobile in a waterproof ( or so i thought) bag and this was dropped in the sea. Straight away, after realising that the bag was not as waterproof as I hoped, I pulled the phone apart dried it with paper towels and left it to dry.

I have thoroughly dried it out, hot hotel balcony and at home a radiator, then a bag of uncooked rice (5 days now).

However I have since got home and read online that I should have rinsed the phone in tap / de ionised water or alcohol first, prior to drying it and that the residual salt is likely to foul it up if I turn it on... (Makes a lot of sense if you stop to think about it - rather than panicking about getting it dry.)

Not wishing to completely wreck it. I have not yet turned the phone on or rewet the phone..

What would you recommend to hopefully bring the phone back to working order without further knackereing the phone.

I am a little cautious as I do not have to pay my £200 excess for water damage on my insurance.

Would rinsing the phone now, do anything to remove the now dried up salt? what would be the best rinse - de ionised water or isopropyl alcohol?

Any other advice?

Gareth, I am certain that you are running into corrosion damage from the salt water. I would recommend that you disassemble your phone totally. You can find a disassembly guide on here. Clean all the parts with high grade isopropyl alcohol (try 90% and great) and a soft tooth brush or a similar device. You can let all the pieces soak in the alcohol. After that, replace the battery and re-evaluate for any damage. Do not forget to clean the connectors and cable ends, hope this helps. Good Luck.

"Clean all the parts with high grade isopropyl alcohol"

Are you sure ?

Alcohol does not dissolve salt (NaCl)

Distilled water does.

That make sense ?
