How to Handle This

1
Steamer Method for Side Windows - This is our go-to for removing window tint from your car quickly and safely, especially on side windows. Crack the window about a quarter-inch to get under the film's edge. Hold a handheld steamer 1-2 inches from the glass, moving in slow vertical sweeps. This heats the adhesive, loosening its grip without scorching the glass. Skipping this initial heating means you'll be fighting a stubborn bond, leading to torn film and a much harder time.

Peel Slowly While Steaming - Once you've lifted an edge with a plastic razor blade, slowly peel the tint downward while continuously applying steam. The key here is patience; if you rush, the film will tear into tiny, infuriating pieces, leaving you with a mess of adhesive. This is especially critical on a hot, sunny day when the glass is already warm - you don't want to over-heat and risk damaging the window's seals.
3
Ammonia Bag Method for Rear Window - For the rear window, where damaging the defroster is a major concern, the ammonia bag method is safer. Tape black trash bags to the OUTSIDE of the rear window. Then, spray a mixture of ammonia and water generously on the INSIDE of the tint and press the bags against it. Let the sun bake this for about 2 hours. The heat and ammonia work together to break down the adhesive, minimizing the need for scraping. Trying to steam the rear window for too long or at too close a distance can damage those delicate defroster lines.
4
Adhesive Removal on Rear Glass - After the film is off, you'll have adhesive residue. For the rear window, use a 50/50 mix of sudsy ammonia and Grease Lightning (or a similar adhesive remover) applied with a microfiber cloth. Let it sit for a few minutes, then gently wipe away the residue. Using a metal razor blade on the rear window, even cautiously, is a recipe for disaster and will likely ruin your defroster.
5
Final Cleaning - Once all the tint and adhesive are gone, clean the glass thoroughly. For side windows, a steel wool grade 0000 with glass cleaner works wonders for any stubborn spots and leaves the glass streak-free. For the rear window, stick to microfiber cloths and glass cleaner to avoid any risk to the defroster. Skipping a thorough cleaning means new tint won't adhere properly, and you'll see hazy spots.
