Q: Might be a silly question, but when a box of baking powder used for freshening the fridge has expired, can it still be used as a scouring powder? Or has it expired altogether?

Editor: Try adding a scoop to hot water along with a little vinegar. If it bubbles, then the baking soda is still active. I wouldn't use it for baking since it's been absorbing all those refrigerator odors, but it should be good for cleaning and scouring!
Readers, have you had luck using expired baking soda for cleaning?
