Hello there! It can be so frustrating to find a pen mark on a beautiful leather sofa, but don't panic! While the provided links didn't contain specific instructions, I can certainly help you out with some tried-and-true methods.
The key to success is to act quickly and always, always test any cleaning solution on a small, hidden spot first, like on the underside of a cushion. This ensures the method won't discolor or damage your leather.
For a fresh ink stain, the gentlest approach is often the best. Try a simple solution of mild soap, like a dish soap, mixed with a little warm water. Dampen a soft, white cloth in the soapy water, wring it out well, and gently dab at the ink mark. Avoid scrubbing, as that can spread the ink and damage the leather's surface. Once the mark is gone, wipe the area with a clean, damp cloth and then dry it completely with a third cloth.
If soap and water don't do the trick, the next step is usually isopropyl (rubbing) alcohol. This is very effective but can be drying, so that spot test is crucial. Put a small amount of alcohol on a cotton swab or the corner of a clean cloth. Gently dab the ink, trying to lift it off the surface rather than rubbing it in. You should see the ink transfer to the swab. Use a fresh part of the swab for each dab to avoid reapplying the ink. After the stain is removed, it's a very good idea to apply a leather conditioner to the area to restore moisture.
For really stubborn stains, or if you're nervous about using home remedies, your safest bet is to purchase a commercial leather ink remover stick or cleaner. These products are specifically formulated to remove ink without harming the leather. Just be sure to follow the product's instructions carefully.
Whatever you do, please avoid using harsh cleaners like nail polish remover, bleach, or abrasive scrubs, as these can permanently damage your sofa's finish. If the stain is large, old, or on a very delicate type of leather, calling a professional leather cleaning service is always the best option.
