Saddle soap is good for softening leather but is not a very good cleaner. Saddle soap should be used sparingly on leather, as it is alkaline and can actually damage leather over time. Caring for your leather products is not difficult but there are a few things to keep in mind.
Leather is an organic material. Though it is preserved through tanning it can still mold, mildew or decay if not treated properly. After exposure to too much heat, moisture, cold, or dryness, it is likely to need some care.
If you need to clean dirty leather, such as a saddle or horse halter, first wipe it clean with a soft, damp cloth and let it dry. You can use a bit of mild saddle soap if desired. Once it is dry, apply a small amount of conditioning oil with your hands and rub it into the leather.
Pieces such as straps or a leather halter, should be laid flat to dry if they get wet. Place wet leather in a well ventilated area at room temperature. You can hang harnesses, leashes, and belts and allow them to dry thoroughly. Remember, never place your leather items in direct sunlight. You should also keep them away from heat vents as this can dry out the leather.
