Yes you can but it will have the effect of drying out the leather and possibly discolouring the area. Baby oil is very effective as it thins the ink and treats the leather simultaneously
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.
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.
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.
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!
Alcohol might. Before you do that I would try Mr. Clean Magic Erasers. They work wonders. I have seen it remove permanent marker off of a wall. Use the one without the scrubber on it so you don't scratch your furniture. Alcohol might but could damage the finish on the leather. Please do not use Magic Erasers on leather - they are designed for hard surfaces and act like a fine sandpaper so will remove the top finish on the leather which will be expensive to replace.
Wipe the leather down first with vasoline. Worked for me.
With an ink stain on a finished leather, immediate action is preferable to letting it absorb. Blot the stain as much as possible. In an inconspicuous area try a white cotton ball or cloth and isopropyl alcohol . Work in small circular spots, allow to dry and repeat if necessary.
you like it till you have all the ink off of it and on your tong. lol
Ink has been made out of flowers for centuries by using alcohol. As the alcohol evaporates off of the flower, you are left with the pigment that can be used as ink.
Try using the Mr. Clean's magic eraser. I've used it to get ink off of a number of surfaces.
Nurses often use plain medicinal alcohol (from a drugstore) to remove ink from white poly-cotton uniforms. Always test a small spot first. Remember that medicinal alcohol will appear to "spread" ink so use a small amount at first to a small stain, then dab with more alcohol as needed. It is best to apply alcohol to white rag (old washcloth if possible) rather than pour it from the bottle. You could also apply using Q-tips or cotton balls; use clean one to re-apply.
A leather cleaner specifically designed for black leather would be the most effective product to clean stains off a black leather chair. It is important to follow the manufacturer's instructions and test the cleaner on a small, inconspicuous area first to ensure it does not damage the leather.
Try a paper towel moistened with rubbing alcohol; many inks are soluble in alcohol.
