MarkThe Vintage Glove Forum is made up of a bunch of very nice fellows who can help you with this dilemma. There are already quite a few threads devoted to this very topic.
I like to use vaseline after cleaning... it brings back lustre and restores the supple nature of the leather with no damaging effects whatsoever. But many of the guys over there will swear by saddle soap for cleaning and lanolin for restoration.
If you peruse the site long enough, you'll even see where to buy the best cleaning products. The link is below... Best of luck!
