Oh no, finding a dye stain on your leather sofa is definitely a stressful moment! While the provided search information wasn't helpful for specific steps, I can certainly give you some expert advice on how to handle it.
The absolute first rule when dealing with leather is to act fast and always test any cleaning solution on a small, hidden spot first, like on the back or underside of a cushion. This will ensure the method you're trying won't cause any discoloration or damage to the leather's finish.
For a fresh stain, start with the gentlest method. Mix a little bit of mild soap, like a clear dish soap, with warm water to create some suds. Dip a soft, white cloth into just the suds, wring it out well, and gently blot the stain. Try not to scrub, as that can push the dye deeper into the leather. Work from the outside of the stain toward the center. Afterward, wipe the area with a clean, damp cloth to rinse it, and then pat it dry with a soft towel.
If the soapy water doesn't work, you can cautiously try a bit of isopropyl (rubbing) alcohol. Dampen a cotton ball or the tip of a clean cloth with the alcohol and lightly dab at the stain. You should see the dye begin to transfer to the cotton. Be very gentle and keep dabbing with a clean part of the cotton ball until the stain is lifted. Because alcohol can dry out leather, it's important to wipe the spot with a damp cloth afterward, dry it, and then apply a good quality leather conditioner to restore moisture.
For very stubborn stains, or if you're dealing with delicate or expensive leather, your safest bet is to call a professional leather cleaning specialist. They have the right tools and products to treat tough dye stains without harming your beautiful sofa.
