Ah, the classic case of an aspiring artist mistaking your prized leather sofa for their canvas. A felt pen mark can feel like a permanent scar on your sanctuary of relaxation. The provided context, I must say, was about as useful as a chocolate teapot, offering only website menus instead of actual solutions. So, let's toss that aside and get down to business.
First, do not panic and start scrubbing like you're trying to erase a dark secret. You'll only make the ink bleed and create a larger, more abstract "masterpiece." Your initial weapon of choice should be a dedicated leather cleaner. If you don't have one, your next best bet is a cotton swab lightly dipped in isopropyl (rubbing) alcohol. The key here is to dab, not rub. Gently blot the ink mark, using a fresh part of the swab for each dab to lift the ink away. Before you go all in, test the alcohol on a hidden spot, like under a cushion, to make sure it doesn't also remove your sofa's color. That would be trading one problem for another.
If the alcohol trick fails or seems too risky, it might be time to call in the cavalry, which in this case is a specialized leather ink remover stick or kit. These are designed specifically for this kind of catastrophe and are much safer for your sofa's finish. Follow the product instructions to the letter.
Whatever method you use, once the ink is vanquished, it's crucial to follow up with a good leather conditioner. Cleaning agents, especially alcohol, can strip the natural oils from the leather, leaving it dry and sad. A quick conditioning will restore its moisture and have it looking less like it just survived a traumatic event.
