The Leather Cleaner Brush is what you need for your well-worn products. Densely packed horsehair will allow you to gently rub off any set in dirt and grime that have accumulated over the years without damaging the leather. Best used in companionship to our all-natural Leather Cleaner. It is recommended to rinse the brush in between uses as to not carry over any excess dye that may have come up while cleaning.
