Newly installed window film has a 30-day curing period, during which it is recommended to NOT wash it. After that curing period, you may clean your filmed glass the same way you wash unfilmed glass:
- You can use Windex, GlassPlus, or any ammonia-based product.
- You must use a SOFT cloth or paper towel, or a rubber squeegee.
- You CANNOT use any abrasive materials or razor blades, as these tools will damage your film.
Window Film Cleaning Technique
Below is a technique you can use to clean windows with film. If you have a rubber squeegee on hand, that would be a helpful tool to use in step 6!
- Start by wetting a soft cleaning cloth or sponge and wringing it out.
- Thoroughly spray the surface of your window with your ammonia-based cleaning solution.
- Use your damp cloth to clean the surface of the glass, applying gentle pressure as needed to remove smudges, fingerprints, and grime.
- Thoroughly rinse your cloth with water to remove the cleaning solution.
- Use the cloth to rinse any remaining solution from the window surface.
- Starting at the top and working your way down the window, dry the glass in horizontal passes using a dry, lint-free cloth with gentle pressure.
Some additional tips that will help you avoid frustrations or damage while cleaning your window film:
- We recommend using a separate cleaning cloth for the inside and outside of the window. On a similar note, do not use the same cleaning cloth that you use on your window film to wipe down your window sills or frames.
- Do not apply heavy pressure to the film when cleaning it.
- For best results, don’t leave your film wet after cleaning.
As you can see, cleaning your window film is fairly low-maintenance and does not require any special products or chemicals. You likely have all the supplies you need in your home or office already – all you need is a clean, soft cloth and Windex!
