Oh no, dealing with a lingering poop smell on a leather sofa is definitely a tough situation, but don't worry, you can usually tackle it with the right approach. While the provided search results didn't contain specific cleaning instructions, I can certainly guide you through the process based on general expert knowledge. The key is to clean the mess and then neutralize the odor-causing bacteria without harming the leather.
First, if there is any solid residue left, gently scrape it off with a dull edge, like a plastic spoon or spatula. Be careful not to press too hard or spread the mess. Next, create a gentle cleaning solution. Mix a small amount of a pH-neutral soap, like a specialized leather soap or even a mild baby soap, with lukewarm water. Dampen a soft microfiber cloth with this solution, wringing it out so it's not dripping wet, and gently wipe the affected area. It's crucial not to oversaturate the leather, as too much water can cause damage. After wiping, use a separate clean, damp cloth to "rinse" the area, and then immediately dry it with a third, dry cloth.
Now for the smell. The most effective way to eliminate organic odors is with an enzymatic cleaner. These products use special enzymes to break down the odor-causing proteins completely. Look for a cleaner that is specifically labeled as safe for use on leather. Before you apply it all over the spot, always test it on a small, hidden area of the sofa first to make sure it doesn't cause any discoloration. Follow the product's instructions carefully, which usually involves lightly spraying the area and letting it air dry.
If the smell still lingers after the enzymatic cleaner has dried, you can try sprinkling a light layer of baking soda over the spot. Let it sit for several hours or even overnight to absorb any remaining odors, then vacuum it up using a soft brush attachment. Be aware that baking soda can be drying to leather, so it's very important to follow up this step by applying a good-quality leather conditioner to the entire sofa to restore its moisture and keep it from cracking.
If you've tried these steps and the smell persists, it may have soaked deep into the cushion's filling or the sofa's seams. In that case, it might be best to call a professional leather cleaning and restoration specialist for help.
