Olympus TG4 overpressurisation

I've heard one way to try to save a camera immediately after a salt water exposure is to submerge it in fresh water and let it soak. (Preferably distilled water, but that's never available when you need it.) The idea being that the fresh water will essentially do the same thing as a dunk tank and wick away the salt before it starts corrosion.

Then you of course have to dry it out, but at least that's conceivable.

I wonder if there are any signs of salt exposure inside the areas of the camera you can easily view, like a battery compartment?

So this is the quandary you face, and the answer probably depends on the observed information.   Salt is the devil and washing it out is essential, but do you risk doing more damage with water?   As you note, you're not going to get pure water.   Rubbing alcohol will evaporate and is preferable if you can get sufficient amount.   Easy when shore diving near a drugstore, not so when off shore, and not the kind of item you can pack in your luggage for flight.

It was 13 years ago I had the YS-110 compartment flood, but that does seem to be independent of the rest of it.   I can't recall if they had alcohol or vinegar, or if I made due with water.  But I did rinse that, to get the battery corrosion out, and then toothbrush the metal contacts.   It looks ugly, but it works.   I'm going to try to sell the pair, but that one goes for a big discount.
