Hello there! Tackling the stubborn smell of cigarette smoke in a leather sofa can be tricky, but it's definitely possible to get it smelling fresh again. It often takes a bit of patience and a multi-step approach since leather is porous and can hold onto odors.
A great place to start is with a gentle but effective cleaning solution. Many people have success using a mixture of equal parts white vinegar and water. Before applying it all over, it's very important to test the solution on a small, inconspicuous spot to make sure it doesn't harm the leather's finish. If it's safe, dampen a soft cloth with the mixture, wring it out well so it's not dripping, and wipe down the entire surface of the sofa.
After cleaning, you'll want to address the lingering odor. Baking soda is a fantastic natural deodorizer. You can place open boxes or bowls of baking soda around and under the sofa cushions to help absorb the smell from the air and the material. Letting the sofa air out is also incredibly helpful. If you can move it to a well-ventilated space, like a garage with the door open or even outside in a shady spot for a few hours, the fresh air can work wonders.
Once the sofa is clean and has had time to air out, finish the job by using a good quality leather cleaner followed by a leather conditioner. The conditioner is a crucial step because cleaning can strip some of the natural oils from the leather, and conditioning will restore moisture, keeping it soft and preventing cracks.
For very persistent smells that just won't seem to go away, you may hear about options like using an ozone generator. However, these machines must be used with extreme caution as they can be hazardous, and it's often a job best left to professional cleaning services that specialize in smoke and odor removal.
