Run out of air freshener? Ever had that happen to you? You have a housefull of guests and someone made a deposit in your bathroom and the bad smell is overwhelming?
Smelling an unpleasant odor in your bathroom, and you need to cover it up fast, simply light a wooden match in the middle of that room. Lighting a match produces sulfur dioxide. This chemical is so strong that it hides most other odors from our noses for a short time. Not a permanent fix, but a remedy for an embarrassing situation.
