Home-centric weblog Re-Nest explains:
Old news is good news! Crumpled up newsprint is an effective odor-eater, and once it has done the job you can still toss it in the recycling bin, or use it to clean your windows: Newspaper + vinegar spritz = streak free shine.
It can actually deodorise pretty much any enclosed space, too, not just drawers. If your fridge is starting to smell funky, for example, you can crumple up some newspapers, spritz them with water, and throw them in your fridge to clear it up.
