When your tint is first installed there will be some noticeable bubbles in the tint that may linger for up to a week or ten days, dependent on outside temperature and the amount of direct sunlight. These bubbles may look like golf ball dimples or appear to be streaky. They are actually okay and are created as a result of the water that is trapped in the process of creating the seal between the window and film. Over time they will work their way out of the film and dissolve. However, if they linger for longer than ten to fourteen days you should check in with your installer and get their opinion on what, if anything, needs to be done to remove them and get a proper seal between the window and film.
There are times when bubbling can indicate a breakdown of the film. Usually there will be some bubbling when there is adhesive failure. Fortunately, the product that is used by Midwest Tinting has a limited lifetime warranty on auto film, a lifetime warranty on residential and a twelve-year warranty on commercial film. These warranties cover bubbling, delamination, demetalization, adhesive failure, and discoloration. Any of these may occur over time due to excessive sun exposure, use of the wrong chemical in cleaning solutions or a breakdown of the UV inhibitors.
To help prevent bubbling you should avoid using common window solutions such as WINDEX or 409 because they contain large amounts of ammonia. You should also avoid using vinegar because of its acidity. The best solution for prevention of problems is to use a soft rag with mild soapy water or any product that says “for use on tinted windows” on the packaging. We sell a great product that is called HI-SHEEN. It is a white foamy product that leaves no streaking or residue. Please ask our store attendants about this product on your next visit.
