Good as new
Baseball gloves can be rather expensive, but their sentimental value often transcends their price. Even if we try to take good care of them, they are bound to get worn down with use. Since baseball mitts often carry with them plenty of memories, we want to be able to keep our gloves as memorabilia and pass it down to our children in good shape.
For the leather to get soft and flexible, baseball mitts must be broken in. If you want to keep them in good shape, one way of softening the leather without ruining the gloves can be achieved using Vaseline. Instead of investing in leather conditioner, which might be too rough on the gloves, rub some petroleum jelly on the gloves using a washcloth and allow it to soak in for a couple days.
