The only product I use is just mink oil. The stuff comes in a tin, normally used for shoes or boots. It has to be pure mink oil, not a synthetic or with stuff like silicon in it like Einyodeler said.
Use Murphy's oil soap to clean it, it won't hurt leather either, than let it dry and goop some mink oil on your hands and rub it into the leather like a lotion. get it all gooped up and covered in the mink oil and let it sit for 8 hours or so.. overnight even.
Then, take some terry cloths and wipe all the mink oil off, buffing with clean cloths as you go. It will smell a bit like the mink oil at the start but within a few days, the leather smell should come back.
I did this to a jacket that had been left out in the rain and was stiff as a board and it came right back to new.
BTW I got this technique from a website on.....leather care for S&M and Bondage equipment...
yes, laugh, but I figured they would know how to take care of dirty leather and it works
