how to get rid of pesky smells

from Real Simple:

In the refrigerator, foods frozen for too long can "make your pie crust smell like a substance from another planet." Wipe down the freezer with a cotton pad dipped in vanilla extract. Wipe down refrigerators with a 50-50 mix of vinegar and water.

In the sink, vegetable refuse often gets trapped in the garbage disposal. So "give the disposal something nicer to chew on." Dropping in the peels of a lemon, orange, lime, or grapefruit, while the hot water runs, "should do the trick."

In a dank basement, subterranean smells can be difficult to dispel. Try cutting an onion in half and leaving it on a plate. "Once the initial salad-bar aroma dissipates, you'll have fresh (non-oniony) air."

For Tupperware, soak containers overnight in warm water and baking soda. For glass jars, bathe them in a mix of 1 teaspoon powdered mustard to 1 quart warm water.
