you can use the stuff that brooks sells > http://www.wallbike.com/brooks/proofideandspanner.html < or probably any other leather conditioner. i've used the stuff that comes with my filson boots for example. i just rub or pore it on and let it sit overnight, wipe off the rest. if it's really been abused or old, i put a lot on and stick the saddle in the oven on warm and let it heat up some. don't forget it's in there though! brooks saddles smell pretty bad if they start roasting!! they're the best saddles ever made imo, and really easy to maintain... there's a pretty good reiew of them here as well... > http://www.cyclingnews.com/tech.php?...ews/brooks_b17 <
