When my car was new the leather seats were a matt finish. I bought some leather seat care wipes and the drivers side became shinier after a few days. I really didn't expect that to happen. It is now 2.5 years ago since I used them and wonder do you chaps use any leather care products on your cars and if so what? I have read that only a gentle wipe with water moistened cloth is all that is required. What do you all think?
