Hello there! Dealing with a pen mark on your lovely leather sofa can be a real pain, but don't worry, there are a few effective ways to tackle it. The provided search results weren't very helpful, so I'll share some trusted methods from my expertise.
The most important first step, no matter which method you choose, is to test it on a small, hidden spot on your sofa first. This could be on the back, or under a cushion, just to make sure the cleaning solution doesn't damage or discolor your specific type of leather.
A great place to start is with rubbing alcohol (isopropyl alcohol). It's a classic remedy for ink stains. Just dampen a cotton swab or a corner of a soft cloth with the alcohol. Then, gently dab at the pen mark. Avoid scrubbing, as this can spread the ink. You should see the ink start to lift off the leather and onto your swab. Keep dabbing with a clean part of the swab until the mark is gone. Afterwards, wipe the area with a clean, damp cloth and then dry it completely with another soft cloth.
If you want a gentler approach, you can try a simple solution of mild soap and warm water. A specialty leather soap like saddle soap is ideal, but a very gentle dish soap can also work. Mix a little bit of soap with water to create some suds. Apply only the suds to the stain with a soft cloth, dabbing gently. Wipe clean with a damp cloth and dry thoroughly.
After you've successfully removed the stain and the area is dry, it's a very good idea to apply a leather conditioner. Cleaning, especially with alcohol, can strip some of the natural oils from the leather. A good conditioner will restore that moisture and help protect your sofa.
