Removing cigarette smoke odor from a leather sofa can be a challenging task because the smell permeates not only the leather surface but also the stuffing and foam inside. A comprehensive approach, combining surface cleaning with deodorizing methods, is often the most effective strategy.
First, begin by thoroughly cleaning all leather surfaces. A highly recommended product for this is saddle soap, which is specifically formulated to clean and condition leather. Alternatively, you can wipe down the sofa with a soft cloth dampened with a solution of equal parts white vinegar and water, or even water and vodka. Before applying any cleaning solution to the entire piece, it is crucial to test it on a small, inconspicuous area to ensure it doesn't cause discoloration. After cleaning, it is essential to apply a quality leather conditioner to restore moisture and protect the material.
To address the odor that has seeped into the cushions and the air around the furniture, you can use absorptive substances. Generously sprinkle bicarbonate of soda (baking soda) over the entire sofa, including in the crevices and under the cushions. Let it sit for several hours or overnight to absorb the smell, and then vacuum it off completely using a soft brush attachment. Placing open bowls filled with white vinegar around the sofa for a few days can also help neutralize airborne odors.
Airing out the sofa is another critical step. If possible, move it to a well-ventilated area, such as a covered porch or an open garage, for several days. Fresh air and good circulation can significantly reduce the smell. Be sure to keep the sofa out of direct sunlight, which can cause the leather to fade and crack. For persistent odors, you might consider using a commercial spray like Ozium or, with extreme caution, an ozone generator. However, if the smell remains deeply embedded in the inner foam, the most reliable solution is to hire a professional furniture cleaner. They have specialized equipment and treatments that can reach deep into the upholstery to effectively eliminate the source of the odor.
