How do I remove protective film from metal sills?

The builder did not immediately remove the protective film from the sills and slopes (all metal) and now, when the house is already built, this film in some places is a little bit fuzzy, peeling in places, but I can not remove it – it is removed in pieces of 2-3 mm. Given the size of the slopes and sills such work on the "plucking" will last for months. Is there any way to quickly remove the film without damaging the metal itself?
