Older, low quality window films will eventually deteriorate with age and have to be removed. Two of the most common symptoms of failing film are the dreaded "purple film" and "bubbling film".

Purple film is caused by non-metallic dyes in the film breaking down and changing color. At this point, the films effectiveness for heat rejection and UV protection are in question. 

Bubbling film is a sign that the adhesive used to apply the tint to the window is failing. After a single bubble appears, many more will follow.

If you attempt to remove the window tint simply by peeling, you'll probably end up with a sticky mess on the glass that will take several hours to scrape. Window film is constructed in layers and although it seems like you’ve removed all of the film by simply peeling it, I can almost guarantee there are still some layers left on the glass, which require scraping with a sharp, 6 inch razor blade.

At Tri Valley Glass Tinting, we have the tools and expertise needed to properly scape that old, existing window film from your glass without damaging the glass or even cracking your window. If you are interested in restoring your glass to its original, non-tinted state, please give us a call.
