Answer:
Due to exposure to air, magnesium reacts and oxide of Magnesium is deposited on the ribbon. The ribbon must be cleaned to effective burn it.

When exposed to air, magnesium reacts with the oxygen in the air and forms oxide of magnesium - Magnesium Oxide which deposits on the ribbon. To effectively burn the ribbon, it has to be cleaned
