Description

BACKGROUND OF THE INVENTION

This application claims priority to Provisional Application No. 62/673,517 filed May 18, 2018 . This invention is directed to an improved product and method for cleaning table tennis paddles.
During a game of table tennis, the table tennis ball picks up dirt, grime, and oil from the hands of the players as well as from the table playing surface. These substances are then transferred to the table tennis paddles each time the ball comes in contact therewith. Collected dust and dirt on the paddles can weaken the natural tackiness along the rubber surface of the head, which can in turn lead to a decrease in the rubber's gripping ability. As can be appreciated, a well-maintained paddle head is vital so that the players can spin and control the ball during play. Therefore, the paddles should be cleaned at least once after each match in order to provide optimal performance.
Current solutions for cleaning most table tennis paddles are either detergents, rubber cleaning foams or sprays, or simply water that is applied by using a sponge. Typically, a player pumps a small amount of solution from a bottle and applies the solution to the paddle, rubs the surface and then wipes away dirt and grime with a separate cloth or sponge.
Ingredients in many detergents are often times harsh and can even be rather abrasive. The ingredients in these detergents can make the rubber dry out and become brittle over time, shortening the useful life of the paddle.
Further, a detergent solution or rubber cleaning foam is typically stored in a bottle, which is not easy to carry around or store.
Accordingly, it would be desirable to provide an improved method and product for cleaning a table tennis paddle which overcomes the advantages described above.

SUMMARY OF THE INVENTION

Generally speaking, in accordance with the invention, an improved method and product for cleaning a table tennis paddle is provided. The product preferably comprises an individually wrapped wipe that is pre-treated with a unique cleaning formula. A table tennis player can easily clean his or her paddle with the wipe without having to apply water or a cleaning solution. In use, the wipe is removed from a storage packet, storage pouch or storage container, and applied to the paddle by gently rubbing it over the surface of the paddle, going with and against the surface texture of the paddle, in order to wipe away accumulated dirt, oil, and grime. After cleaning, the wipe is normally thrown away.
Accordingly, it is an object of the invention to provide an improved method and product for cleaning a table tennis paddle.
Another object of the invention is to provide a wipe that is designed for cleaning a table tennis paddle.
A further object of the invention is to provide an improved formulation to be used in cleaning a table tennis paddle.
Still other objects and advantages of the invention will become apparent from the following description.
