I have a sure fire technique, but it cost me an elk once. Seriously, it cost me a nice 5x5 bull. But it does work!
Get a 2" wide rubber band from an inner tube, not too tight, but tight enough. Wad up a few kleenex or a couple feet of TP, and stick it on the lenses, and put the inner tube over the scope.
99% of the time, when you pull the band off, the kleenex will pop right out and fall away..... unless you have a spooked 5x5 Colorado Bull Elk running across the hillside 50 yards from you, then you can't get it out with a screwdriver!
(The lenses will be clean and dry 100% of the time!)
