It was probably a no-no, but I used a Mr. Clean Magic Eraser on mine. It dulled the finish just a bit, but who knows what the crud was so I didn't figure I was losing anything. You could test a small spot first.

Car detailing places would probably know of some things to clean ink if the good old stand-by of hairspray doesn't work. Most of the leather cleaners we've used in the past were for general grime. My cows must be pretty tough because some mild soap and water worked just fine. I can't believe how well this couch has held up with my crew.

My couch has an ink stain also. Even being careful rubbing it out changed the texture and water left a new larger stain. I think the type of leather may make a difference - distressed or smooth. - Carol
