Microwaving your baseball glove.... Simply not a good idea. In fact a terrible idea.
The thing is, what makes the leather of your glove soft and pliable is the moisture content (oils) in the leather. If the moisture in your glove gets hot in the microwave, it accelerates evaporation causing the leather to dry out. What does that mean? A stiffer glove, not a softer glove.
Don’t cook your glove. It will shorten the life of the leather. Instead, add moisture with Mitt-Spit Glove Oil conditioner to soften your glove. A softer leather makes your ability to catch a ball a lot easier than with a stiffer leather. Think about it. Don’t turn your glove into a hunk of wood. Keep it soft and supple for better ball handling.
It is true a warm baseball glove will absorb Mitt-Spit Glove Oil faster than a cold glove. Warm the glove gradually. For example, put in in a car that is sitting in the sun for a bit. Then apply the Mitt-Spit Glove Oil and it will absorb in more evenly and faster. Go to Mitt-Spit Products to buy the correct products. You’ll notice the difference quality makes.
