What is the grainy black soot coming from my tennis racket?

If you've noticed a grainy black soot coming from your tennis racket, it's likely due to friction between the strings and the ball. This is a common occurrence, especially if you play on hard courts.

The soot is caused by the wear and tear on the strings as they rub against the ball. When the strings make contact with the ball, they create friction, which generates heat. This heat can cause the strings to break down and release small particles of carbon, which appear as a black soot.

The amount of soot produced will vary depending on the type of strings you use, the tension of the strings, and the surface you play on. Natural gut strings tend to produce less soot than synthetic strings, and strings that are strung at a higher tension will also produce less soot.

While the soot is not harmful, it can be unsightly and it can also affect the performance of your racket. If you notice a lot of soot on your racket, you may want to consider restringing it with new strings.
