It is cleaned to remove the layer of magnesium carbonate which gets coated after being in contact of air. So to make it react vigorously it is cleaned with sandpaper

Magnesium ribbon should be cleaned with sand paper before burning in air due to formation of white layer of magnesium oxide on its surface which hinders the burning of magnesium.
