Hello there! I'm happy to help you with that tricky pen mark on your leather sofa. The provided links didn't contain specific instructions, so I'll draw on my general expertise to guide you through the process.
The most important first step, no matter which method you choose, is to test it on a small, hidden area of your sofa. This could be on the back, under a cushion, or on a flap of leather underneath. This ensures the cleaning solution won't discolor or damage your sofa's finish.
For fresh ink, your best bet is to start with the gentlest method. A simple solution of mild soap and lukewarm water can sometimes do the trick. Dampen a soft, white cloth, wring it out well so it's not dripping, and gently blot the stain from the outside in to avoid spreading it.
If that doesn't work, the most common and effective solution is isopropyl (rubbing) alcohol. Dampen a cotton swab with the alcohol and gently dab at the pen mark. You should see the ink start to transfer onto the swab. Be patient and use a fresh part of the swab for each dab to avoid reapplying the ink. Once the stain is gone, wipe the area with a clean cloth dampened with water to remove any alcohol residue, then pat it dry.
After cleaning, especially when using alcohol which can be drying, it's a great idea to apply a good quality leather conditioner to the area. This will help restore moisture and keep your sofa looking its best. Just be sure to avoid harsh cleaners like bleach or nail polish remover, as they can cause permanent damage to the leather.
