Just curious of peoples thoughts of this.

I ahve a game used glove fielding glove and I notice after having it on display for 2 years that the glove has dried out a bit and lost some of it's shine. Just curious of people's thoughts on if giving a light leather treatment on the glove would be good or bad.

I wouldnt put the treatment on heavy at all but slightly so the glove was not completely dried out either. Curious on peoples thoughts on this. I know there are some that would certainly not think anything should happen to it after it is not in use any longer, but would like to hear opinions. I probably will not treat it at all, but would that be a no-no?
