Table tennis rubber is one of the most important parts of a table tennis paddle. It is responsible for providing the majority of the spin and speed that a player can generate. Over time, table tennis rubber will lose some of its tackiness and begin to harden. This process can be accelerated by exposure to sunlight or heat. When this happens, the performance of the paddle will decrease significantly.
To maintain your table tennis rubber in top condition, it is important to clean it regularly with soap and water. You should also avoid exposing it to sunlight or heat whenever possible. If you notice that your paddle is not performing as well as it used to, you may need to replace the rubber.
