Oiling a baseball glove is an important part of maintaining its quality and extending its lifespan. It helps keep the leather soft and pliable, preventing it from drying out and cracking. A properly oiled glove will also be more resistant to dirt and moisture, and it will break in more easily.
There are a few different types of oil that can be used on a baseball glove, but the most common is neatsfoot oil. Neatsfoot oil is a natural oil that is derived from the feet of cattle. It is a good choice for baseball gloves because it is relatively inexpensive, it does not darken the leather, and it does not attract dirt and dust.
