Our balcony, where my wife and I used to smoke, still smells like a**. The window has been open since day one, we've cleaned every reachable surface and replaced every fabric in the place and it still reeks. Is there something that will knock the stink out forever? All that's out there is paint and tiles now and if we scrub the paint too hard it'll come off. Freebreeze isn't working either (well S. Korea's version of the product "free-ba-ree-jah"). It masks the scent just like any other perfuming agent but once it's gone the stale cigarette air remains.
