Having been specially designed for phenolic billiard balls by the very same engineers that developed the Aramith phenolic billiard balls, the new Aramith ball cleaning agents will not affect their unique features, as opposed to other agents. Directions for use: Shake well the bottle - Apply the cleaner upon the ball (for an optimal result, use the Aramith Micro-Fiber Cloth) - Rub well - Make the ball shine with a piece of dry cloth or paper or with an electrical buffer.
