Long after a cigarette is extinguished, the odour hangs around and "third-hand smoke," residual carcinogens and heavy metals, remains on surfaces. If one of those surfaces is your leather chair, getting rid of the smoke residue and odour requires a cleaner that will not damage the leather. With certain cleaners and care, you can remove the residue and eliminate the odour from your leather chair.
Vacuum your leather chair with the brush attachment to pick up loose dust and particles.
Wipe down the chair with a soft cloth or sponge and a leather cleaner or saddle soap according to product instructions.
Wipe away the soap with a water-dampened soft cloth or sponge wrung out thoroughly. Excess moisture can damage your leather chair.
Dry the chair with an absorbent towel.
Point a fan at the leather chair for 15 to 20 minutes.
Sprinkle baking soda over your leather chair liberally and leave it undisturbed overnight.
Vacuum up the baking soda in the morning.
Use only soft materials on leather as it is easily scratched.
Commercial cleaning products may contain harsh chemicals which can damage leather. Only use products specifically made for leather.
