I know the Z2 is Waterproof for 30 min at maximum 1.5 m deep in freshwater.
Saltwater, as far as I have read, is an absolute no go.
But my question is just, why?
Saltwater has a little higher thickness so it can no enter the phone as easy as freshwater does.
But it is highly corrosive to unprotected metal.
But of course the phones frame is made of aluminium wich is highly corrosion proof up to a pH-value of 9, saltwater has something arround 8.
So from the simple chemical point there should be no problem and Youtube shows in several videos that some brave people allready have done this.
So, what are the effects of saltwater and will it be enoght so wash it is freshwater afterwards?
Thanks in advance
