Smoking in your home can decrease the value of your home as well as your furnishings. If you are buying used furniture, you can often get a discount on sofas that have a smoke odour. Luckily, you can remove the smoke smell yourself with household products and methods.
Baking soda is a natural way to absorb smells from porous materials such as leather. Because baking soda is completely dry, you can even apply it to unfinished leathers, including suede and nubuck, which can become damaged by water-based cleaning solutions. To use baking soda, sprinkle it onto the leather couch and let it sit for several hours. Vacuum the baking soda off the leather couch after it has absorbed all of the smoke smell. Repeat the process if necessary.
A distilled white vinegar-based solution will not only clean your leather sofa, but it also will remove the smell of smoke. Mix 1 cup of vinegar with 2 cups of water. Use this solution on a soft cloth to clean the surface of finished leather sofas. Do not over soak the sofa. Once you have coated the entire sofa, rinse the area with clear water. Dry it completely to prevent watermarks from developing.
Ventilate and Purify
Another household way to remove the smoke smell in a leather couch is to increase ventilation and use natural air purifiers. Open all of the doors and windows in the room, and keep it well ventilated. If the weather permits, leave the couch outside for a few days to increase ventilation. If you leave the couch inside your home, place open bags of coffee grounds around the room to help absorb the smoke smell over time.
