Don't use air fresheners of any kind, they're all cancer chems.

I read advice sometime, I don't remember the recipe, but they put something plus cinnamon in the oven at a low temperature with the door slightly ajar.

Plates of baking soda also helps. If you have like an old rug or sofa thats smelling up the place, sprinkle a good layer of baking soda over them and let it sit for 24 hours, then vacuum it up. Works wonders for smells.
