If water gets behind the liner in a vinyl pool will it ever dry up or go away, or should I make some attempt to vacuum/dry it? The walls of the pool are galvanized (I think) metal.
Reason I ask, is the liner popped out of the track in a small section yesterday, and when I pulled it away and up to put it back in today, I noticed water behind it, and the metal was a bit rusty. As far as I can tell, there are no leaks in the liner - I assume water got behind there other times in the past when the liner was pulled away (i.e. over winter, a few section of liner popped out).
