The film fully “cures” over the next week to 10 days. Dry, sunny weather speeds curing; wet, cold weather prolongs it. During curing, the film may initially look hazy or cloudy; this effect will disappear with time and/or exposure to heat. Do NOT roll down your windows during this curing period
Wait at least 3 days after window film installation before cleaning your windows. Clean the film with application solution and a low-lint cloth or low-lint paper towel. It is safe to use ammonia-based cleaners if the cleaner sits on the film for no more than two minutes.
