It is quite common to find a slight haziness and/or small water pockets after the film was applied to your car or home windows. This is usually called curing. It is a necessary part of the adhesive bonding process.
For car window, it takes about 3 or 7 days for the film to be fully cured. While for home or commercial windows, it may take up to 30 days. How long the film is fully cured is completely according to the film type and weather conditions.
It takes a time for the remaining water used in installation to evaporate through the film. So the curing process is slow. Sputtered and heavy security films take the longest to dry and will take longer for any hazy appearance to disappear.
You can only clean your car or home windows after films are dry and cured. The best cleaner is a simple solution of water and a small amount of soap. Just put them altogether into a window tinting sprayer, then clean with towel and squeegee dry with window tinting handled squeegee.
You may also clean the film surface with any normal strength glass cleaner. Products with ammonia will not damage the film if used in reasonable quantities and if the film is not left to soak in it.
Do not use any abrasive cleaners, industrial strength glass cleaners and/or any other window cleaning tools that may scratch the window film. Remember, the surface of the film is coated with a scratch resistant not scratch proof coating.
