Finish the following sentence with the best choice: Is there an easy way to remove mud from the bottom of your shoes?

Choices:
- Remember to carry a cleaning brush with you if you are travelling by foot in a rainy area.
- If the mud is still wet, let it dry first. When the mud is dry, take a brush and the shoes outside, and brush the mud off with a medium firm brush, making side to side motions until all the mud and dust comes away. Finally, wipe all surfaces with a soft cloth. If the mud is very caked on, you can also loosen it up with a paring knife. Just be careful you don't slice any holes in the shoe.
