1. Place the foot-wiping artifact at the bottom of the footbath or bathtub to ensure that it is firmly fixed on a flat surface.

2. Add a proper amount of warm water to the footbath or bathtub, and add foot bath salt or washing liquid according to personal preference.

3. Step on the bristles or grooves on the foot-wiping artifact with your feet, so that your feet can fully contact with the foot-wiping artifact, which can play the role of cleaning and massage.

4. Gently push the foot rubbing artifact with the sole of the foot or fingers to make the bristles or grooves rotate on the sole of the foot, thus increasing the massage effect.
