Cleaning the dirt off your leather hiking boots extends their life and can be easily done with this boot-cleaning brush. Brass/Perlon bristles scrape dirt off nylon, as well as suede and nubuck leathers. Soft textured rubber edge cleans light-colored areas and erases scuffs off nubuck leather. Rubber tip removes dirt from grooves and crevices. Comb teeth clean out caked-on dirt from lug soles.
