Magnesium is a very reactive metal. When it is kept in the open air it can react with the gases present in the air. Cleaning will remove those impurities formed due to the reaction with air.
Magnesium very reactive element which rapidly reacts with oxygen in the air to form a white layer of magnesium oxide and this layer will not burn.

To remove the Magnesium oxide layer from the ribbon which may prevent or slow down the burning of magnesium ribbon.

Unwanted impurities deposited on the magnesium ribbon can be removed and only pure magnesium can be used for the reaction.
