Removing 3M window film from house windows can be done with some patience and the right tools.

Here’s a general guide on how to remove 3M window film…

1. Prepare the Work Area – Clear the area around the window and lay down protective coverings to catch any debris or adhesive residue. Gather the necessary tools and materials, including a utility knife or razor blade, a spray bottle with soapy water or adhesive remover solution, and a clean, lint-free cloth or sponge.
2. Loosen the Film – Use a utility knife or razor blade to carefully score the edges of the window film, creating small cuts or perforations along the perimeter of the film. This will help to loosen the film and facilitate the removal process.
3. Moisten the Film – Spray the surface of the window film with a solution of soapy water or adhesive remover to moisten and soften the adhesive. Allow the solution to soak into the film for several minutes to loosen the adhesive bond.
4. Peel Back the Film – Starting from one corner or edge of the window, carefully peel back the window film using your fingers or a plastic scraper. Work slowly and gently to avoid tearing the film or damaging the underlying glass surface.
5. Remove Adhesive Residue – After removing the window film, you may encounter adhesive residue remaining on the glass surface. Use a clean, lint-free cloth or sponge soaked in adhesive remover solution to gently scrub away any remaining adhesive. Alternatively, you can use a razor blade or scraper to carefully scrape off stubborn adhesive residue.
6. Clean the Window Surface – Once all of the window film and adhesive residue have been removed, clean the window surface thoroughly with a solution of water and mild dish soap. Rinse the window with clean water and dry it completely with a lint-free cloth to remove any remaining residue and ensure a clean, smooth surface.
7. Inspect the Glass – After removing the window film, inspect the glass surface for any signs of damage or scratches. If necessary, polish the glass with a glass cleaner or polishing compound to restore its appearance and clarity.

It’s important to work carefully and methodically when removing 3M window film to avoid damaging the glass or surrounding surfaces.
