Magnesium ribbon should be cleaned before burning because *Magnesium is a reactive element if it is kept open in the air it reacts with oxygen in the atmosphere and form the layer of magnesium oxide which does not support in burning

Magnesium ribbon should be cleaned with sandpaper before burning in the air because of the following reasons:

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
