As well as corrosion, if the salt gets into the phone and hits the moisture, there's more danger of a short circuit.
If the phone's useless, I'd be tempted to buy some distilled water and dunk it in that and skoosh it around (technical term) while wearing marigolds or similar to avoid contaminating the distilled water. Don't have the battery or SIM in while you're doing it. Dry the surface & put it in a food bag in the airing cupboard with some silica or rice.
Considering all the effort, though, you might be better off just putting the SIM in an unlocked eBay replacement? Is it a really expensive 'phone?

It is because of the conductivity of the salt that corrosion occurs, even without connecting the power the salt can cause electrical currents to be generated between two different metals, e.g. printed circuit board and the legs of a component. This causes the corrosion, (very quickly).
Distilled water is useless for cleaning the boards, if you do have a spillage or as in this case drop it down the bog it should be cleaned using Isolpropyl alcohol cleaner which is for cleaning circuit boards, this will in most cases drive the water and indeed any salts from the circuit board and dries a great deal quicker than just placing on a radiator over night, (though no electrical supply should be connected until it has all completely evaporated ).
Putting the circuit board in a food bag could kill it quicker than dowsing in salt, these boards are electrostatically sensitive and the static created would often mean certain death to components.
The air needs to circulate around the board to assist evaporation, otherwise condensation can gather. If after drying it is not going straight back into the 'phone then a proper bag similar to the ones Hard drives come in can be used for storage.
However I do agree with this statement:-
Well entwisi, have I passed the test? Can I be added to your geeks list now?
Electronic!!!
I repair, down to component level, they fit the cables, that I attach everything to!
(of course PLC's have made a dramatic change, now none of them can work with 1960's gear it does their heads in).
A quick swap of the main board, computer produced it probably only costs a fiver, don't you just love this throw away society?

well if you can fix it for me for a fiver then please do

I will remember that the next time I need something electronic repairing
