Should you wash your dice?
If the dice require more thorough cleaning, put a small amount of soap (such as Palmolive) on a wet paper towel, work into a lather, then gently wipe your dice and rinse in cool water. Dry immediately with a non-abrasive towel. You should only need to do this very rarely.
Do metal dice scratch each other?

Can dice be made of wood?
Today, modern dice are usually made of plastic, although recent years have seen a surge in popularity of dice made in unusual ways or from rare materials, such as metal, wood, stone, and even 3D printing. Modern metal dice are typically made from a zinc alloy and then plated with a more expensive metal finish.
