I am not sure about cleaning the glove, but I have always used clear Neutral Shoe Polish in a very thin layer, applied with a toothbrush, to get in cracks and crevases, then polish well, to remove excess so you don't have any whitish build up. Vasaline is a petrolium based product, and is not recommended. Clear shoe polish will not harm the leather in any way, like other chemical based products recommended earlier in this post.
