Recovery after a smartphone swimming party !

Dropped my smartphone in a bucket of lather, three days ago ..... soaking wet inside the SD slot, battery cabinet and SIM card slot ..... and ....
moisture between the LCD and front glass !!!
Screen was completely filled with grey stains and spots ..... !!!!
So patiently dried all asap and started to dry with a föhn .... not too hot of course ...
No results .... though.
But repeted föhn actions during the past few days gradually brought some hope, the moisture started to disappear a bit. Today's progress in the picture, I hope the remaining spots will also go away soon ....
