How to care for your Solar Gard window film Film dry-out time: The mounting solution used during the installation of your Solar Gard window film may require a dry-out time. Cold or non-sunny weather conditions can lengthen the dry-out time, while warm weather and direct sun light exposure will shorten the dryout time. Small water beads and a slightly cloudy look may appear during the dryout time. If slow drying does occur, do not become alarmed. The film will dry-out. Do not clean the film for 30 days after installation Window film care and maintenance: To maximize the life of the window film, please follow these instructions for proper care and maintenance.
