Cards are not invincible. They're bound to get dirty. When you open a deck of cards, more often than not, they spread like butter. perfection. Then the oils of your skin starts spreading onto the cards and what you soon get is the illusion of a warped deck... BUT, keep practicing. the oils continue to spread then the deck is back in workable shape... this point is actually my favorite... spreads perfectly and like butter, as a new deck does, but more controllable. If you have real issues with cleanliness. Wash your hands before use. Sing happy birthday twice as you're lathering up. If you want to avoid sweat on cards, baby powder works like a charm. Try not to drop your cards. practice over a bed or clean table if you must. You'll figure it out. Just create a routine... no need to be OCD about it. you'll notice that when handling cards, they don't get that dirt stain look to them as you use them, so quickly.
