Dropped sennheiser mkh-60 p48 in water - Audio Players & Recorders

Hi, 
Wow, nice mic, I hope it survived. 
If the mic wasn't powered on when dropped into the water, you may have a better chance, but even still, if may have survived. How pure was the water? If normal drinking water, just open it up as much as you safely can, and give it a day or two to dry out THOROUGHLY, inspect for any signs of corrosion, put it back together and try it. 
If it was something akin to pond water, or salt water, or a swimming pool, IMMEDIATELY open it up as much as you safely can, and flush it with as pure and as filtered water as you can. Again, give it a day or two to dry thoroughly, inspect for any signs of corrosion, put it back together and try it.
If it doesn't behave normally, contact Sennheiser for advice, and perhaps they can better help with cleaning, or maybe you can just get by with having the element replaced, etc.
good luck!
