How do I prevent/remove cigar odor?
agropyron is right. Don’t leave the butts in the house, and make sure no one crushes out their cigar when putting it out, just lay the butt aside and the cigar will extinguish itself. When you crush a used cigar butt, all the burned tobacco “oils” are released through the split wrapper and really reek up the place.
What always works for me is a couple of shallow bowls filled with ammonia. It absorbs odors and it really seems to work – I’ve used it after parties and it always gets rid of the smell of stale smoke. Be really careful to keep it well out of reach of pets or kids, though. Just pour some in a little bowl and leave it sit for a couple of days – having 3 or 4 little bowls around the room/s is best. Fabreeze (or however you spell it…) spray is also pretty miraculous on lots of smelly fabrics, although I’ve never tried it for cigar smoke. It works really well at neutralizing the bacteria that causes odors.
