I have been cleaning this three year old office that had film left on the windows for all that time while it set vacant and now, no matter what I do to the glass, it looks like this plastic film has burned into the windows and they look terrible. I know I am cleaning them well, but when you step back and look at the window you see these lines that are always there. Is it possible that this film with the hot sun burning into the glass is what is causing the windows to look like this?


Undoubtedly, the film is making the windows hard to clean and contributing to a streaky appearance. However, the film may have been placed there for a reason, possibly for sun control or to add strength to the glass.
As a cleaner, you cannot undo a poor installation over a soiled surface or prevent deterioration from sun exposure. Donít assume ownership of this problem. Just clean the surface as well as you can and let the building owners correct any visibility problems.
