Oh no, finding a biro mark on your lovely leather sofa is always a frustrating moment! The good news is that with a bit of care, you can often get it out. The provided search information wasn't very specific, so here is some general advice on how to handle that pesky ink stain.
The most important first step, no matter which method you choose, is to test it on a small, hidden area of the sofa first. Try a spot on the back or underneath a cushion to make sure the cleaner doesn't damage or discolour the leather's finish.
A very effective and common method involves using isopropyl alcohol, also known as rubbing alcohol. Lightly dampen a cotton swab or the corner of a clean white cloth with the alcohol. Gently dab at the ink mark, being careful not to scrub or spread the stain. The goal is to lift the ink out of the leather and onto your cloth. You may need to use a few fresh swabs as the ink transfers.
Once the ink is gone, wipe the area with a separate cloth that's slightly dampened with water to remove any alcohol residue. Immediately dry the spot with a clean, dry cloth. Because alcohol can be very drying, it's a great idea to apply a small amount of leather conditioner to the area afterwards to restore moisture and keep the material soft and protected.
For tougher stains or if you're feeling hesitant about DIY solutions, a dedicated leather ink remover stick or wipe is your safest bet. These are specially formulated to remove ink without harming the leather itself. Always remember to act as quickly as possible, as fresh ink is much easier to remove than a stain that has had time to set.
