Help maintain and optimize the quality of spin, your carbon faced paddles provide, with Diadem's Paddle Cleaning Block. Meant specifically for paddles that feature a raw carbon surface, and not for Kevlar, or Kevlar composites, the cleaning block gently removes the accumulation of court dirt, and plastic from the ball on the raw carbon surfaces of your paddle. The result is similar to putting your pickleball paddle in a time machine, as after using the cleaning block, it takes paddle spin potential right back to the same level when you first got it.
