THANK-YOU!THANK-YOU!THANK-YOU! We recently purchased new bone leather furniture and our almost two year old daughter got to it with an ink pen. And not one cushion but four of them! The acetone worked like a charm but you must beware because trial and error proved you can discolor it if too much is used and you allow it to sit on the spot instead of wiping it. However the flaw is hardly noticeable because after I removed the ink from the cushions I went back and used the conditioner and protectant and buffed them and they look just as good as new!
