Do you use mink oil on your baseball glove? Think twice. This is what you need to know. Mink oil comes from the fur of a mink. Animal or vegetable oils are never good for leather due to the potential for rancidity. Oil can go rancid.

To understand why, here’s a short chemistry lesson. There are two ends of the animal or vegetable oil spectrum: there are saturated oils at one end and unsaturated oils at the other. Saturated oils are actually stable, while unsaturated oils can be unstable.

There is a scientific measure to prove this. It is called the iodine value. The higher the iodine value of an oil, the less stable it is, which means it is more sensitive to oxidation. Simply put, it will most likely go rancid.

The iodine value of mink oil is between 80 and 95. It’s not the highest, but it’s pretty high up on that scale. By comparison, coconut oil is quite low, around 10. For a broader perspective, olive oil is close to mink oil on the iodine value scale at around 85.

Therefore, mink oil has a fairly high iodine value. But there are 3 other necessary factors. Exposure to air (oxygen), heat and light. This is why olive oil bottles are generally green (not clear glass), stored with the lid tightly closed, and in a cool, dark place.

However, your baseball glove spends a lot of time outdoors, clearly exposed to the sun, air and gets very hot. His glove is exposed to all three factors: air, heat and light.
