My father smoked almost three packs of cigarettes a day up til a few weeks before he died (of lung cancer among other things, no surprise there), and when we went into his apartment to clear it out and clean, you can imagine the smell and the film. We had to get rid of the upholstered furniture, it was beyond help, but I managed to salvage the coffee table and the china cupboard. It took several cleanings with Murphy's Oil Soap to get the sticky nicotine residue (it was a weird orange colour, very bizarre) off the wood, but the pieces finally looked and smelled much, much better.
