|You're paranoid. Are you afraid of getting it wet? Do you use a towel to
dry off the line when you're reeling in? :-)
I don't fish with anything that I'm afraid to get wet, except a can of chew.
Sometimes when streamfishing my reel gets grit in it, typically when I
beach a fish and put the rod down to handle the fish. If I hear that
ugly grit sound, I put the reel in clean water and strip hard two or
three times. It's always worked, so far.
In saltwater you should be using gear designed for saltwater, and a
quick rinse at the end of the day is all you need.
