If you or guests have been smoking in the house, you may notice that the smell has a tendency to linger long after the cigarette is gone. A concoction of metals, carcinogens and radioactive materials make up the residue that sticks around, clinging onto furniture and walls after the smoke has cleared. A leather couch with an unpleasant smoke smell can appear to present a rather frustrating problem, as leather is known to be a difficult material to clean. With a little care and caution, your leather couch can be smoke-free.
Remove loose dirt and dust particles from the couch by using the brush attachment of the vacuum cleaner.
Mix warm water and white vinegar together in equal parts.
Dip a clean soft cloth or sponge into the solution, and wring it out well.
Wipe down the couch thoroughly with the cloth, making sure to remove the cushions and wipe them down as well.
Wipe the couch down with a clean, dry towel to remove excess moisture.
Apply a leather conditioner to the couch as soon as it is completely dry to protect it. Read and follow the manufacturers' instructions carefully for use.
Avoid using harsh chemicals, as this may damage the leather. If you opt to use a commercial product to eliminate the smell, first ensure that it is safe to use on leather.
