What causes leather to lose its natural fat?

Exposure to heat, sweat, salt, and dirt causes leather to lose its natural fat because these elements can degrade the fibers and surface of the leather. When leather is regularly exposed to moisture and heat, it can dry out, leading to the breakdown of natural oils. Sweat and salt, in particular, can attract and hold moisture, creating an environment that promotes the breakdown of the leather's natural fats. Additionally, dirt can act as an abrasive, further removing oils during cleaning or natural wear.

By understanding this, horse owners can take preventative measures to protect their leather equipment, ensuring it remains conditioned and durable over time. Proper care and attention to the environmental factors affecting leather will assist in maintaining its integrity and extending its lifespan.
