Preparing your Window Film for Installation
Add 6-8 drops of mild detergent, such as baby shampoo or dish detergent, to a 32oz spray bottle filled with water to create your installation mixture. Next, use this mixture and a lint free cloth to clean your glass surface. Do not use typical household window cleaners containing ammonia. The chemical will break down the adhesive and ruin it over time. Sprayway Glass Cleaner also works well.
After cleaning the glass, lightly scrape it using a razor blade. This will help remove any stuck on debris. Be sure to test a small area first to make sure the glass won’t scratch. After scraping the window, use your solution and lint free cloth to wipe down the glass again. You can use a paper towel to remove excess solution along the edges. Your surface should be very clean and free of dirt, dust particles and silicone. Carefully measure your window and cut the film to size. You’ll want to oversize the film up to an inch on each side. This gives you some extra room for cutting during installation.
