Ideally - soak the filler spool before putting the line on the reel...let dry, then spool up the line.
Then the night before you go out, a couple spritz to re-condition - no need to soak it.
If you've already spooled the line on the reel - give it a good soaking...let it dry for a couple days, then do the night before 'touch-ups' as above.
