There are two products by Lexol -- cleaner and conditioner -- that someone recommended I use for cleaning the leather seats in my car. They are excellent. Spray on the cleaner, let it sit for a while, then wipe it off with a damp cloth. Rub on the conditioner to keep it from getting hard and cracking.
I purchase the products at a good auto parts store or car shows, but you can order it on line at
www.lexol.com .
