How to Remove Old Tint from Car Windows: A Step-by-Step Guide

Over time, even the best car window tint films will start to show their age. If your windows start showing any bubbling, peeling, discolouration, or a purplish hue, it means that your tint is due for a replacement. 

Getting your old window tint removed and re-tinted is a best practice for many car owners. Not only do old tints make your car look tired, but they are also not safe. This is a delicate process that needs to be done properly so that you don’t scratch your car window. 

Here is a step-by-step guide on how to remove old tint from a car window at home, using easy-to-find tools and simple techniques.

Why Remove Old Window Tint?

It’s worth understanding why removing old tint is more of a necessity than you think. Here are the main reasons:

  • Visibility and Safety: Bubbling or peeling tint is an obstruction while driving, especially at night or in bad weather.
  • Legal Issues: If your tint is peeling, it could be regarded as unroadworthy, especially if it restricts the driver’s vision. Getting it fixed helps you avoid legal penalties. 
  • Aesthetic Deterioration: Faded, cracked, or discoloured film can make even the best, well-maintained car look worse for wear.
  • Preparing for Re-Tinting: If you plan to install fresh tint, removing the old one properly gives you a clean slate on your windows. 

Tools and Materials You’ll Need

To remove your old car window tint, here’s a list of essential tools and products you’ll need in your home:

  • Heat gun or hair dryer: To soften the adhesive under the tint film.
  • Razor blade or utility knife: Helpful for lifting corners and scraping off residue (with care).
  • Ammonia or tint remover spray: Breaks down the adhesive left behind from the old tint.
  • Spray bottle with soap solution: To clean surfaces and keep them moist. 
  • Microfiber cloths: For wiping and drying without scratching.
  • Garbage bags: For soaking your cloth and removing any mess.
  • Protective gloves and mask: Necessary when working with ammonia or chemical removers.

Preparing Your Car for Tint Removal

Before you get started, here’s a few advice on how to remove your tint efficiently: 

  1. Park in a shaded area with good ventilation. Setting up outdoors is ideal if you're using ammonia, and avoid working in a confined space.
  2. If you’re working inside, protect any interior surfaces. Use towels or plastic sheets to cover upholstery and dashboards.
  3. Always wear your protective gear. Gloves and masks are a must, especially when handling chemicals.
  4. A recommended practice is to use a tape around the edges of the window to avoid any damage to your car’s paint. 

Step-by-Step Guide: How to Remove Old Tint from Car Windows

Now that we’ve covered all the basics, here’s how to remove your window tints, step-by-step. 

Step 1: Loosen the Tint with Heat

Start by applying heat to the window tint using a heat gun - a hair dryer works too! Hold it a few centimetres away from the glass and move in slow, circular motions. This softens the adhesive and makes peeling easier, which is the next step.

Step 2: Peel Off the Tint Film

Once heated, use your utility knife or razor blade to lift a corner of the tint film. Be patient here, as ripping your film too quickly may leave more adhesive behind (i.e. more work for you later).

Slowly peel back the film using your hands. If it begins to tear, reapply heat and continue. You can also use the razor blade gently to help guide stubborn sections. However, be careful not to scratch the glass, especially when you’re peeling near the edges.

Step 3: Remove Leftover Adhesive

Now comes the messiest part. Spray the adhesive with ammonia or a commercial window tint adhesive remover. Then, cover the area with a garbage bag or plastic sheet and let it sit for 30 - 60 minutes. You need to do this to soften any stubborn adhesive. 

After a while, check if the adhesive is soft enough and use your razor blade or a plastic scraper to gently remove it. Removing tint glue is tricky, so you’ll need to repeat the spraying and scraping as needed. Be patient during this step!

Step 4: Clean the Window Surface

Once all the adhesive is removed, give your windows a good clean. Spray the window with a soap solution or glass cleaner and wipe thoroughly with a microfiber cloth so that all the dirt is removed. 

Alternative Methods for Tint Removal

If the heat-and-peel method isn’t working for your particular tint, here are a few other options to consider: 

  1. Steaming: Use a handheld steamer to heat the tint evenly. Steamers reduce the risk of placing too much heat on one area.
  2. Soap and Newspaper Method: Spray the tint with a soapy solution, cover it with newspaper, and leave it in direct sunlight. The heat and moisture can help loosen the film.
  3. Professional Adhesive Removers: Available at auto shops, these products are designed to break down tint adhesive quickly. We recommend using ammonia-based window cleaners, degreasers, and citrus cleaners. Spot testing is always recommended, and be careful not to stain the vehicle’s paint and interior trims.

When to Call a Professional

As much as we’d like to DIY our vehicle projects, there are times when removing your car window tint isn’t always straightforward. You should consider getting it professionally removed if the tint is very old or layered, making it harder to peel. 

Windows with defroster lines are also tricky to peel, and can be damaged if you’re not careful. Lastly, if you don’t have the time or tools to do the job, it's easier to call in a professional. 

As a local car window tinting specialist in the Mornington Peninsula, we’ve seen plenty of tint removal jobs go sideways when they are poorly attempted without the right tools or experience. This is especially true when dealing with cheaper, low-quality tint films that were poorly installed to begin with.
