Please read these instructions before cleaning
You may notice that your freshly installed window film has a dimpled, textured, or “lumpy” appearance when looking at or through it. (This is especially true of sputtered metal films.)
Sometimes the film may have a milky or clouded look in spots. This is quite common and a normal part of the drying process.
As moisture from the application solution slowly evaporates through the film, the lumpiness and/or cloudiness will slowly diminish.
Within two to eight weeks it should dry completely, depending on the film product, temperature, and humidity. Normal curing periods range from 7-60 days.
For best results, clean your windows with a soft clean rubber squeegee or cotton cloth and common household-strength glass cleaners, such as Spray Way, Windex, Glass Plus, or silicone cleaner/polishing compounds specifically made for window films. These latter compounds are generally available through your dealer. Follow label instructions for such products. Another excellent and inexpensive window cleaner may be mixed and used as follows:
