I bought some furniture from a friend who smoked and can't get rid of the smell!  We've tried everything- scrubbed with baking soda, Murphy's oil soap, hydrogen peroxide, leaving pans of baking soda in it, pans of vinegar, pans of orange peels....  we even bought a commercial product (can't think of the name of it right now) and still the smell persists!  (And you should have seen the gunk that came off of it!  The metal pieces were all a bronze colour and after we cleaned we discovered the handles of the entertainment centre were gold and the desk handles were silver!)  One piece of furniture is an entertainment centre- it's laminated particle board.  We even sprayed the few exposed particleboard surfaces with the commercial product and another time with vinegar.  The other piece of furniture is a solid wood desk.  There's no upholstery on either.  Please help!  We currently have an air purifier in the room where these pieces are but it still reeks! 

 Hi ...  I still have an old beautiful desk that I can still get wiffs of cigar smoke even after 10 years. Originally, I left the desk outside, in the shade, for a few weeks before even bringing into my house. I then placed charcol pieces (the kind for fish tanks) into bowls and left them in the four drawers for about a month. Hopefully, time will make the smell less offensive, but smoke does seep into wood and it can stay a very long time. Good luck to you ... 

I was just at Wal-Mart yesterday and saw a product made by OdoBan that was specifically used for hard surfaces (wood, floors, walls).  It was a pet stain/smell remover but I am sure you could try it for cigarette smoke.  It was in a trigger-style spray bottle in the pet section.  I would also recommend cleaning it again before applying, maybe try good 'ol ammonia?  You really need to strip off that nicotene tar/residue well.

Thanks for the responses.  I'll see if I can find Odoban products here in Canada, although after the last stuff I used (Odor Xit) I don't have much faith in these products.  And Wal-mart would be my store of last resort for anything- long story.  Fish tank charcoal in the drawers might be an option but I think I'd need a cubic metre of it and just seal the door shut for a month with a radioactive warning label on the door!  Honestly, I cannot believe how much this stuff stinks after all the cleaning we've done!  Even with the door to the room closed and the room air cleaner running the smell radiates out into the hallway.  And I feel pretty certain there is no more of the nicotene/tar residue.  We used pot scrubbers with the Murphy's oil soap and kept cleaning till there was no more staining on the white cleaning cloths.
