The protective film on the security door can t be torn off for a long time, and it s rotten when it

Industrial alcohol rubbing, or gasoline, can definitely wipe off,

Blow the film with a hair dryer, blow it a little longer, and try it

You can find a place that is already a little up, and apply some wind oil essence (or other oily liquid objects) to the place where it is connected to the door, peel it a little more, and then peel it again, and so on several times, and then it will get better and better to peel, be patient! >>>More

If it is not good to tear, you can use a hair dryer to heat the side of the file to blow and tear!
