Fiebing's Black Saddle Soap
Fiebing's Saddle Soap is trusted by leather crafters worldwide as a staple item in their leather workshops. Saddle Soap cleans your fine leather goods while lubricating dried-out leather fibers to ensure long-lasting strength and pliability. You can use saddle soap for edge slicking as an alternative to gum tragacanth and beeswax. Unlike water, saddle soap won't darken the edge of the leather as it keeps the edge from heating up too much while burnishing. Do not use on suede or rough leathers.
Note: Black Saddle Soap may darken light-colored leathers. Only use on dark leather goods.
