How to maintain a table tennis bat with a champion signature?

Ordinary rackets need maintenance, not to mention the signature of the champion. I especially loved playing table tennis when I was a child, so I was a little careful about the maintenance of my racket. Although unprofessional, it can really prolong the life of table tennis bat. When the bottom plate is stored in a dry place, the life of the racket is shortened and the performance is reduced, which is mostly caused by the board being wet. In addition, prevent heavy pressure and damage. In the process of playing ball, we should pay special attention to the collision between the ball board and the table and the ground, and we should not drop the racket, pool table or bump the baffle intentionally because of losing patience. Also pay attention to protect the sponge and the bottom plate. The properties of sponge come from thickness, hardness, elasticity, pore size, number of holes and other factors. Because sponge is an expansive body, it should not be stretched or squeezed excessively during use.
