Right on the money. After I started this thread I emailed Dive Rite and they confirmed that having a bit of water left over is not a problem at all assuming it is clean fresh water. Makes sense. Wouldn't make for very practical diving gear if something that is designed to be used in water could get damaged by water.
When I bought my wing used about a year ago it had not been in the water for 2 years.
It made a rattling noise when you shook it and when I unscrewed the OPV a bunch of salt crystals fell out, previous owner had put it away without draining it properly after a dive in salt water...
Thoroughly rinsed it there and then and have used that wing for 70ish dives since and it has worked flawlessly and it still looks great on the inside.
Not saying salt is harmless for your gear, but I do believe there's a lot of people who will crap their pants if I tell them I sometimes just toss my gear aside for a couple days/a week after a dive in salt water if I know I'm going on a fresh water dive soon (something I was told by two of my GUE instructors they often did and they never had an issue).
The main factor here is probably time, it takes quite a while for it to actually do any damage to your gear.
Then again I know people who will spend two hours cleaning every inch of their gear after a dive in fresh water because they're afraid "the dirt can damage it".
