Nike basketball is slippery when it is stained with dust. What should I do?

It only shows that the quality of the basketball you bought is not very good. Try not to get dirty. After all, basketball is not easy to play, so there is no way to change it. You can't change its leather or its shape and size. Try not to wet the basketball, dry it immediately after it is accidentally wet, and clean it up after each play. Basketball has been played for a long time, and it may be better to wear it.
