I got a 500, 300, and a few 200g saltwater fish tanks @ my crib. Drop your phone in there for a minute, kiss your iPhone good bye, irregardless how much you clean it. You try reaching down to the bottom of a 500g tank and see how fast you get yours out. LolYeah if it were me, I'd rinse everything out/off with clean water after being exposed to ocean water. That stuff can be quite potent over time.
