Every time I brush black Nike sneakers, there will always be white marks on the Internet. How can I easily get rid of these white prints?

After washing shoes, you can wrap the net with absorbent paper (toilet paper or napkin), so that when the shoes are dry, the white matter will be absorbed on the paper instead of staying on the net.

As for whether there is a way to avoid using paper, there may be, but it will cost a lot of money to handle it in a specialty store. It's better to handle it with paper, which is simple and cheap.
