Glycerine Saddle Soap Bar by Fiebings This 100% glycerine bar restores leather to its full-bodied suppleness and buffs to a rich, satin finish. An excellent cleaner and preservative. Fair and Horse Show exhibitors often shampoo prize horses and cattle with glycerine bars to impart a healthy sheen to their coats. To preserve, restore and clean leather articles, rub a damp sponge over Fiebing's Saddle Soap Bar and apply it evenly to the leather. Let the glycerine soap penetrate the leather until the surface is dry. Buff briskly with a soft cloth for a lustrous finish.
