Spray tint is an aftermarket effect applied to windows to reduce the amount of light passing through the glass. Window tinting is available in various sizes and strengths to customise most vehicles. Many states have laws regarding the maximum visible light transmission of window tinting. All bodyworks garages or window tinting application companies offer removal services. However, a do-it-yourselfer can save money and remove the spray tint on a sunny afternoon with a few simple tools.
Douse the tint with an ammonia cleaner and allow it to soak. Be sure to spray the edges well; the cleaner will seep into the edges and dissolve the tint quicker. Once the ammonia has set, spray the tint again for complete saturation.
Work the razor blade into the corner of the tint's edge. Spray more ammonia, then continue to push the blade underneath the layer of tint. Keep working the razor and spraying ammonia until the tint begins to lift from the glass. Do not hurry the job. Ripping up the tint will leave a gunky glue layer that can be difficult to scrape later.
Spray a paint solvent, if the razor blade and ammonia method did not work adequately, then use a very fine spray paper to water sand the tint from the glass. Use a bucket of hot water at the end to wash away any grime and grit left over from the process.
Dry the glass with a lint-free towel once the window has been rinsed.
Wear safety and protective equipment when working with hazardous chemicals and sharp tools.
