Whether you have invested in a leather sofa, leather coat, designer handbag, or an attaché case or other fine leather goods, protect that investment by taking care of the leather by cleaning and conditioning; replace the natural oils that are removed through regular use. We recommend an annual cleaning especially in high usage areas, family rooms, home theaters, conference rooms, wherever people congregate. When an accident occurs.mop up spills immediately with a clean soft, dry cloth. Remove as much of the residue as possible.
