get a cloth and soak it with gasoline
As a teacher I have gotten marker on just about anything it was possible to get marker on and never have been able to get marker out of leather. You could try a shoe maker to see if he has something to remove it or go the store where you bought the couch and see if there is something that will remove it.
Use a dye or a marker. Heh.
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.
If your imitation leather couch has become sticky, you can clean it to remove the tackiness. Simply wipe the tacky area down with baby wipes and allow to air dry.
To properly sanitize a leather couch, start by vacuuming it to remove any dust and debris. Next, mix a solution of mild soap and water, then dampen a cloth with the solution and gently wipe down the couch. Be sure to dry the couch thoroughly with a clean, dry cloth. Finally, consider using a leather conditioner to keep the leather soft and supple.
EASY!!!!!!!!!!!!!!!!!!!!!!!!!!! _*Just get a knife and cut the couch and pull out the cushions*_ THAT EASY : :) Have a good day :)
If it is a smooth leather you could try a leather cleaner. There are good ones on the market that will remove things like this. If the it is suede you could use a suede brush on it and brush up the nap.
Get a bottle of isopropyl alcohol out with a roll of paper towels. Wet the paper towel and blot the stain. Keep blotting with the alcohol and paper towel until the stain is gone. Alcohol works great on ink stains on almost any surface, but permanent markers take a lot more work. Try any Whitening Tooth Paste.
Leather couches are low maintenance and resist spills and stains easier than a fabric couch. Be careful with ink pens and sharp edges that can scratch or cut the couch. Invest in a leather repair kit if purchasing a leather couch.
One can purchase a black leather couch from stores such as DFS, NEXT, Blacksofas and Homebase. One can also purchase a black leather couch from websites like eBay and Gumtree.
To effectively sanitize your leather couch and keep it clean and germ-free, you can use a mixture of water and mild soap to gently clean the surface. Avoid using harsh chemicals that can damage the leather. Additionally, you can use a leather conditioner to maintain the quality of the leather and prevent it from drying out. Regularly vacuuming and wiping down the couch with a damp cloth can also help remove dirt and germs.
Use alcohol. Rubbing alcohol might work, but denatured alcohol from the hardware store is better. Dampen a cloth wrapped around your finger with it and rub. Keep changing to a fresh spot on the cloth, and re-dampen it with the alcohol. It may take a few minutes, but that should get it all out.
