Is there a fix to salt water immersion of camera?

Water, any kind of water is a conductor of electricity. If you truly dried out the camera and it will not power up it probably shorted out. The one thing that might clean any minerals or salts out of the camera that is readily available is rubbing alcohol. With the battery removed, submerge the camera in rubbing alcohol and swish it around, then drain it and let it dry. Do not use anything like a hair drier to do it because alcohol is flammable. After it is dry, install a charged battery and see if there is any sign that it powers up. This is a real long shot and I would use this as a last resort. Getting the camera fixed would probably cost as much as the camera. One other idea, if you have a Homeowner's Insurance policy, is to see if they would cover it.

I hope that will help .

Salt as you know is very corrosive. If the damage is not to severe place the camera in a bag of rice to absorb excess moisture or place camera on top of a water for 3-4 days (dry warm air may evaporate deep seated moisture). Again if salt water remains in the camera then there is a possibility of serious damage. The camera may have to be taken to a professional and cleaned - preferred.
