How to remove window film is probably the last thought to enter your mind when you’re having film installed. However, in most cases the adhesive bond that keeps the window film in place will rarely last more than a couple of years. As it begins to show signs of wear, you should realize that it won’t be long until the adhesive no longer holds, and you will need to come up with an effective way to remove window film.

The best way to remove window film often depends on the type of window being treated. However, there is one process that is generally safe and effective for most windows, including windows in vehicles that may have defroster strips that shouldn’t be scratched or damaged. This method is preferred to remove window film without all the scraping. It takes less time and effort and still achieves the desired result.

The tools needed to remove window film are things you probably already have around the house. They include a razor or penknife and you will also need ammonia or ammonia based cleaner such as Windex®. You will also need something to cover the vehicle interior or other surfaces below windows that are being treated to catch the drips of ammonia or cleaner as you remove window film.

The first step to remove window film is to lift the corners gently. For this step, you will probably need the razor or penknife, but you can try lifting it with your fingers. Pull it slowly, pulling away as much as you can without tearing the window film. Spray ammonia or Windex® on the uncovered area and work it under the film. Try to pull more of the film away, and continue applying cleaner, working it in, and pulling.

To remove window film on windows that do not have obstructions such as defroster strips, you can also score, or cut several areas. Spray ammonia or Windex® onto the entire window, working it into the scored areas with a clean, damp rag. Begin pulling at these areas as they begin free up. In this case, it doesn’t matter if the film comes off in strips instead of all in one piece.

The last step to remove window film is to make sure that all remaining adhesive residue is removed. This can be accomplished by gently scouring with steel wool. Take care to work around defroster strips if they are present. Wipe with a clean, dampened cloth as you go. You can also try products such as concentrated Goo Gone®, which works wonderfully on sticky substances or you can look for specialty products made to remove window film.
