Solutions I've seen include
- Lotion your hands up before performing
- Don't lotion your hands up it will dirty the cards
- Use hand sanitizer before handling the cards.
- Hand sanitizer contains rubbing alcohol which will dry your hands out worse.
Once in a while I'll see the correct answer or at least the one I consider correct. So what do I think is the correct answer. I believe the way to have performance ready hands is with a hand care regimen. Now I know most magicians are men and so are opposed or unfamiliar with the idea. But as I see it the only way to have supple skin is to do like the ladies do and work on it every day. As such after I take a shower I apply lotion to my hands way up past the wrists most of the way up my forearms. I go so far up the arm because some of the things I do require the spectator to hold my wrist and I want it to be as presentable as possible. What all this does for me is insures that any time I pick up a deck of cards my handling won't suffer from dry hands. By the time I pick up a prop there is no left over residue on my hands to ruin anything. I have to say this method works for me, though your mileage may vary and all that.
