Why does lighting a match seem to help with certain bathroom odors?

Public Comments

1. The smell of the extinguished match covers up the smells. It doesn't eliminate them. As seen on Mythbusters.
2. because bathroom odors consist mainly of methane... when a match is lit an oxidation reaction is triggered by the flame and the methane reacts with oxygen to produce carbon dioxide therefore the methane is being 'used up'
3. yeah, covers the odor with the nauseating sulfur smell of the match.
4. The sulfur in the match absorbs odors.
5. matchheads contain sulfer when burnt overwhelms any other odors you may be smelling
