Jason Markk's original brush, now relegated to the task of handling heavy duty cleaning. The durable, stiff bristles are especially suited to jobs like cleaning the sole and other areas which you needn't worry about damaging delicate surfaces.
*When cleaning delicate materials such as premium leather, suede, nubuck, cotton, canvas and knit; we highly recommend using the Premium Shoe Cleaning Brush. The softer hog bristles are better suited for use on delicate surfaces.
