All window film deteriorates with age and eventually have to
be removed. Two of the most common symptoms of dying
film are the dreaded "purple film" and the "bubbling film".
Purple film is caused by non-metallic dyes in the film
breaking down and changing color. Bubbling film is a sign
that the adhesive used to apply the tint to the window is
drying out. After a single bubble appears, many more will
follow.
Before going futher, KINGTINT.COM recommends that you
have the window tint removal performed by a trained
professional.
The process can take up to 3 hours and is not easy or
pleasant. Improperly removing window tint can damage
defroster lines and radio reception. Is the $50 you save
worth the time and risk? If you aim to get the car tinted
again, many tint shops will throw in the window tint removal
for free with a new tint job

1. Cut the garbage bag in roughly the shape of the window,
spray soapy water on the outside, cover it with the black
trash bag and smooth the plastic flat.
Most window tint is constructed of multiple layers of film.
When left under the hot sun, the garbage bag will absorb
heat, helping the film peel off in one piece.

2. Protect all inside surfaces near the rear window with a
tarp: speakers, rear light, and upholstered surfaces, then
spray the entire window film with undiluted ammonia.
Undiluted ammonia has a strong smell. It is
recommended that you hold your breath or wear a face
mask

3. While the ammonia is still wet, trap the ammonia
against the window film with another trash bag or plastic
wrap. Park the car with the rear window facing the sun for
an hour to soften the tint's adhesive.

4. Now we can start peeling the window film. Use your
fingernail or razor blade lift the window film in a corner of
the window, and try to peel the film off in one entire piece.
Keep the tint moist with ammonia as you strip.
Use a razor blade to scrape off any tint that did not peel. Be
careful not to cut the defroster lines.

5. Remove the any residual adhesive with ammonia and
Super-Fine steel wool, wiping with paper towel before it
dries.
Remove the exterior trash bag, and clean window
thoroughly with glass cleaner.
