Hello there! Dealing with a smelly leather sofa can be a bit tricky, but don't worry, there are some great methods you can try to get it smelling fresh again.
First, you'll want to give your sofa a thorough cleaning. Start by vacuuming the entire piece, using a soft brush attachment to get into all the cracks and crevices where dust and odor-causing particles can hide. Next, you can create a simple but effective cleaning solution by mixing equal parts white vinegar and water. Dampen a clean microfiber cloth with this mixture, making sure to wring it out very well so it's just damp, not wet. Gently wipe down the entire surface of the sofa in sections, and then immediately dry each section with a separate clean, dry towel.
If a general cleaning doesn't completely solve the problem, the odor might be a bit deeper. A great trick for absorbing musty smells is to use baking soda. If you can, unzip the cushions and sprinkle baking soda on the interior fabric or foam. You can also sprinkle it on the fabric underside of the sofa. Let it sit for several hours, or even overnight, and then vacuum it all up thoroughly.
Another fantastic, natural deodorizer is sunlight. If you're able to, try moving the sofa to a sunny, well-ventilated spot for a few hours. The fresh air and the UV rays from the sun can do wonders for killing off mold, mildew, and bacteria that might be causing the smell. Just be careful not to leave it in direct, harsh sunlight for too long. If the smell still lingers after these steps, it might be coming from deep inside the cushion foam, and it could be worth calling a professional for a deep cleaning.
