For another example, body odor is that yucky smell that clings to you when you get sweaty. Sometimes we abbreviate "body odor" as "B.O." It's pretty gross, but a shower can quickly get rid of the odor.
Just like we deodorize ourselves, we can also deodorize fabrics or even the air. If someone smoked a cigarette inside your car, you'll have to deodorize the seats to get the odor out. If your kitchen is full of cooking odors, you might have to open a window to let the odors waft out, or spray a deodorizer into the air to kill the odors. Here's Sheldon deodorizing his kitchen.
