How to Remove Old Window Film in House Windows
- 1). Grasp any loose edges of film and pull gently. Sometimes the film will lift in large pieces and you can pick it all off. Older, brittle film will only disintegrate into small pieces impossible to pick off the glass.
- 2). Put the ammonia in the spray bottle and spray the window film. Saturate the surface. Cover with the dry cleaning bags or sheets of plastic wrap.
- 3). Uncover the window and respray with ammonia every 15 minutes for one hour.
- 4). Push at the edge of the window film with the razor blade in the holder. After an hour to ammonia should have done its work and softened the adhesive, and you should be able to use the blade to scrape off the old film.
- 5). Wash the windows with soap and water on a nylon-covered sponge to remove all traces of adhesive. Rinse thoroughly.
