If your beloved, aging baseball glove is showing signs of wear and tear—cracking and hardening of the leather—you can give it a second lease on life with an occasional olive oil rubdown. Just work the oil into the dry areas of your mitt with a soft cloth, let it set for 30 minutes, then wipe off any excess. Your game may not improve, but at least it won’t be your glove’s fault. Some folks prefer to use bath oil to recondition their mitts.
