The great Ray Holes of Grangeville, Idaho developed a leather conditioner he called “Saddle Butter” many years ago. It has a combination of beeswax, neatsfoot oil, carnauba wax and a variety of other ingredients. I’ve used it liberally over the years on new and used saddles. The saddle will never be cleaner than when it is new, therefore it is a good idea to treat all the saddle parts that will come into direct contact with the horse. Stirrup leathers, fenders, back cinch, billets, the back side of the flat plate rigging receive special attention. Warm moisture from the horse carry with it salts that are damaging to leather. It is recommended that a product with some wax in it be used to seal up these areas that are most vulnerable. Applied liberally and allowed to render into the leather, then buffed off with a sheepskin leaving a smooth finish is important. This way, airborne dust will not stick to the surface of the leather. I buy Ray Holes Saddle Butter by the gallon.
