Playing cards quickly become sticky and stick together due to constant touching with the hands.

 

All you need is a little baby powder to keep the cards nice and loose and stop them sticking together when you shuffle them.

Put the playing cards in a plastic bag together with a teaspoon of baby powder. Tie up the plastic bag and shake the cards vigorously so that the powder is well distributed.

Now take the cards out and they should feel nice and smooth and new again.
