There are several steps to cleaning and maintaining hiking shoes or boots safely.
Clear away loose dirt and dust with a soft-bristled brush or a damp cloth before cleaning. Scrub your shoes gently with a mild, hiking-specific cleaner mixed with water, paying special attention to stubborn stains. Allow them to air dry in a cool, well-ventilated area away from direct heat or sunlight after thoroughly rinsing them with clean water. Dryers and high temperatures should be avoided as they can damage the materials.
After your shoes have dried, use a waterproofing spray or wax to protect them from future moisture and dirt. Follow the application's manufacturer's instructions. These steps will help you maintain and extend the life of your hiking shoes or boots.
