Hello mate !!
Here's your answer
This is done to remove the layers of magnesium oxide and magnesium carbonate from the surface of magnesium ribbon. These layers are formed as a result of reaction with atmospheric oxygen and carbon dioxide. Magnesium ribbon is cleaned by rubbing with sand - paper after which magnesium ribbon burns smoothly.
Hope my answer will help you :))
