Just use nail polish remover. Seriously. I got some on the leather seat in my car and used it and it came right off. Do not leave it on long, then follow it up with a leather cleaner. I used Armor All. Good luck.
Believe it or not!......Perfume, expensive or inexpensive, doesn't matter. Spray perfume on a q-tip and clean ink off your leather couch, coat or purse!
get a cloth and soak it with gasoline
Wipe the leather down first with vasoline. Worked for me.
Try Goof Off, it will soften the edges and you can possibly peel it then.
Rubbing alcohol can be used to remove ink stains from leather. Dampen a cotton ball with rubbing alcohol and gently dab the ink stain until it starts to lift. Be careful not to oversaturate the leather and always test a small, inconspicuous area first to ensure it won't damage the leather.
If you mean ballpoint ink, take a clean cloth and a bottle of hair spray. Spritz the ink with the hair spray, wait a few seconds and wipe.
maybe try cleaning it or not spill the oil spill clean with lighter fluid
You can remove urine by using a product called D-molish Now.
There are several methods for removing ink from leather - some better than others. First off, ink does not come off easily especially if it has been there for any period of time. If that is the case, have it done by a professional. Also, if it is a suede then it will not come off without marking the leather. If you are going to do it yourself, be very GENTLE - it is very easy to damage leather beyond repair. Very gently rub stained area with a clean white towel using rubbing alcohol/surgical spirit. Let dry completely.
Recently I found that nail polish remover can remove ink stains from blue denim pants. Maybe it will work for you.
To remove biro (ink) from white leather, you can use a cotton swab or cloth lightly dampened with rubbing alcohol or hand sanitizer. Gently dab the stained area, being careful not to saturate the leather. After the ink lifts, wipe the area with a clean, damp cloth and let it dry. Finally, condition the leather with a suitable leather conditioner to restore moisture and prevent damage.
Try milk and dab it on let it sit for a while, then sponge off with clear water.
