Answer:

Magnesium ribbon must be cleaned before burning in air so that the layer of magnesium oxide (which is formed due to reaction of magnesium with air) can be removed in order to get the desired chemical reaction.

it should be cleaned before burning due to the following reasons

magnesium very reactive element with rapidly reacts with oxygen in the air to form a white layer of magnesium oxide and its 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 deposits on the magnesium ribbon can be removed and only pure magnesium can be used for the reaction .
