Vinegar works very well for removing odors.
When cleaning something out (for example, a garbage pail—see the baking soda trick from a few weeks back), wash it with vinegar as opposed to anything else. It will remove any foul smells and neutralize the material. Following that, keep it fresh by using the baking soda trick.
Another thing I love about vinegar is that it can remove cooking odors if you simmer it in a separate pot while you’re cooking. What I do is designate the far burner for the pot with vinegar. I place about a cup of vinegar in the pot, simmer on medium, and voilà! The smell of broccoli and salmon is gone!
And for those looking for an extremely low maintenance trick, simply leave about ½ a cup of vinegar in a small bowl to deodorize while cooking or if there is a smoker in the house.
