I have an old school corcor supercorsa white saddle (plastic w/ leather cover). I know it's gonna get little cracks in the saddle (it has from only one day of riding), but I'm wondering what the best way to preserve the finish is so that I can easily remove stuff like jeans ink (which is wiping off pretty easily right now).

anyone have any experience with cleaning or treating white leather saddles or leather covered saddles?...Will a shining with a little brooks proofide do anything to help me?
