If you are not a professional table tennis player, you can wipe your sweat on the rubber of the table tennis racket. My coach taught me this. Also, the board of your racket is very important. The handle of a table tennis bat absorbs sweat. When buying a racket board, the darker the better. "Note: The deeper the better, not the color on the paint, but the original color of the board." )
The handle of the racket can absorb sweat to prevent the racket from falling off because of sweating when playing. Wiping sweat on the racket rubber will help the rubber stick (professional athletes have special potions, so they don't need to sweat). I remember the sports channel also said.
