Onion Deodorizer
Onions may smell aggressive in the kitchen, but they have some odor busting characteristics that work just as well as the chemical competitors. If your basement smells like mildew, or if you have stinky litter boxes down there, cut an onion in half and place it down there on a plate. The allicin in the onion will suck the bad smells out of the air almost immediately.
