The wheels have been used for a long time and need to be cleaned. Here, you can choose a wheel cleaning brush.

Firstly, ensure good contact between the floor brush and the wheel surface. Then, apply pressure on the floor brush with appropriate force and angle to thoroughly clean the stains on the wheel surface. During the cleaning process, an appropriate amount of water spray or cleaning agent can be used to assist in the cleaning effect. At the same time, be careful not to apply excessive force to avoid damaging the surface of the wheels.
