Windows with film applied are easy to clean without damage to their appearance as long as a few common-sense guidelines are followed:
1. Use a soft, clean cloth, soft paper towel, or clean synthetic sponge
2. Use a soft cloth or squeegee for drying the window
3. Use any normal glass cleaning solution which contains no abrasive materials.
The availability of scratch resistant coatings as a standard feature of quality films has virtually eliminated the need for extra special precautions in cleaning.
