Strike 3 or 4 wooden kitchen matches. Make sure they are fully alight, then blow them out and wave the smoking match sticks around the room until they stop smoking. It removes (not covers up) all kinds of odors, from damp dog, to doggy 'accidents', to cooked Brussels sprouts without any perfume-y after scent.

I used to have a small bought gel-type deodorizer in my car that was "raspberry tea" scent. When it ran out, I washed out the container and kept it. A few weeks later my daughter commented that the car was stinky.
I have a chair in my bedroom that is holding up a fan. I don't like the cats to go underneath it. I put this can under the chair and it has made the whole bedroom smell wonderful when the fan is on and when it is off.
Best and cheapest deodorizer is white vinegar. It also kills germs. This is all we use in our house. It doesn't mask odors, it removes them.
Using Small Cat Food Tins for Deodorizing. I have a few tips to make the house smell good. I use the 3 oz. cat food tins.
I love using those many colored jars of deodorizing gel "beads" to suck away odors. I tried "reviving" an old, dried up jar of beads by watering it through the holes in the top lid.
