What is the best way to remove tint from car windows?

The cheapest route wouldn't be bad either.

Answers:
it came of my 3000gt's window pretty easy, i used a spray bottle of ammonia, i think it was half water half ammonia. Sprayed it on the windwo, parked the car out in the sun and then taped a black trashbag on the inside to attract moresunlight. It peeled off like scotch tape after that. If it is old tint ( like my back window ) it may take a few treatments.

Other answers:
bricks usually do the trick, just toss them as hard as possible

You can do it yourself. Use a razor blade to scrape off the tint and peel away. Then to get the residue off, use lots of hot soapy, sudsy water.
you don't say if it is a aftermarket tint like a film or if the windshield came tinted. if it came tinted th tnt is between the layers of glass and is not removable. films and sprayed on tints remove differently. you can check with local auto glass shop for best solution.
By far the most often asked question is "How do
I remove this old, purple, bubbled tint off the rear
window without destroying defroster lines?"





Time: 1-3 hours


Materials:
Warm sunny day
Tarp
Large plastic garbage bag
Undiluted Ammonia
Windex (a glass cleaner)
Paper towels
Fine steel wool
Razor blades

Tools:
Slotted Screwdrivers
Phillips Screwdrivers



Tips: The difficult thing about removing tint is that most film is constructed of two layers of tinted polyester. When you try to peel the film off the glass, the top layer will usually pull right off leaving the second layer behind. This second layer will not peel off, it will just flake and tear like a price tag.
Step 1:


To over come separation between layers you must soften the adhesive so that both layers peel at the same time. This is very important, if you peel the just the top layer, you may as well just use razor blades as there is no way to peel the second layer off without picking at it for a few hours. You MUST try to peel both layers at once.

NOTE: You are more than likely to damage one or more of your defroster lines, when this happens, the cut line will not work anymore. Some cars have radio antennas mounted alongside the defrosters made of the same material. If you damage these, your radio antenna will not work! Be careful! Taking it to a tint shop to be done greatly increases the odds of saving the lines, but even a tint shop can not promise to save your lines, sometimes the film is just to far gone.

Step 2:
First, clear the window of any obstructions, like the brake light, speaker covers etc.

Step 3:
Next cut open the garbage bag so that it will be big enough to cover the entire window. Spray some water on the outside of the back window and the lay plastic bag over the glass. Cut away excess plastic so that it is now roughly the same shape as the glass.

Step 4:
Next, lay a tarp over rear deck and seat, spray ammonia liberally on the inside of the back window. (Ammonia is very strong, I suggest you hold your breath during this step) and cover ammonia soaked tint with the plastic bag so that it won't evaporate.

Step 5:
Park the car with rear window facing the sun for about an hour. The film should now be ready to peel.

Step 6:
When you are ready to start peeling, leave the plastic in place so the ammonia wont dry. Get the peeling started with a razor blade in a corner where there are no defroster lines. Try to peel film off in one piece. If the ammonia dries as you peel, the glue will get hard again, so spray a bit of ammonia on the area as you peel.

Step 7:
Once the film is peeled you will need to scrub the adhesive off with ammonia and fine 0000 steel wool.

Mop up scrubbed areas with paper towels before they dry. Finish up with window cleaner and paper towels.

Removing tint from side windows
Soaking is not nessesary here. You may want to use a simple razorblade holder. Cut a notch onto the upper area of the film so that you have a piece to pull. Try to peel the film, it will probably come off in two or three pieces.
Spray the remaining adhesive with soapy water, and scrape the adhesive off with a razor blade, avoiding the edges of the glass until last to keep the blade sharp. You may need to use a few blades as they dull quickly. Finish up with window cleaner and paper towels. Inspect for missed glue (its clear and hard to see)




Another way to strip using steam


If you have access to a Jiffy steamer or similar steam machine, you can make quick work of stripping. Apply the steam to a small spot for a few moments and use a blade or the spout of the steamer to peel the area just steamed, when you have enough to hold, just peel slowly as you steam just ahead of the area you are peeling.

This will bring both layers of tint off and sometimes the adhesive too, without presoaking for an hour.
Use a blade scraper and get some window tint remover from a car parts store. The blade wont scratch your windows. Taking off window tint takes hours and hours to do. As after you get the tint off you have to scrape the invisable glue off.
The best way to remove tint is to get someone else to do it!
Actually, if you have glass insurance coverage, the first answer works pretty well.
the fastest way, peel the tint off, pour lacquer thinner or gasoline on a cotton cloth to wipe clean the sticky stuff and clean it off with a glass cleaner, it works for me.
use a razor blade with some denatured alcohol or just use some soapy water and the blade.
