Common Problems on Tinted Windows and How to Fix Them

Window tinting is has become an excellent investment among car owners and homeowners because of the various advantages window tint films offer. Such advantages include improvement of the vehicle or home’s visual appearance and protection of people as well as the home and vehicle’s interior against the sun’s harmful UV rays.

But like everything else, window tints deteriorate with age, and their longevity depends on the quality of tint and installation, level of heat or sun exposure, as well as maintenance. Over time, you can face problems with your tints.

What are the most common problems with tinted windows? 

While tinting the windows provides you with perks such as less time and money spent maintaining the windows, it is still crucial to perform routine care and maintenance on the tint films. A well-maintained window tint can prolong its lifespan, allowing you to continue to reap the benefits it offers. In contrast, a poorly maintained tint film can develop minor cosmetic issues over time.

The most common problems with window tints include air/soapy bubbles, hardened water spots, peeling, and scratches.

How to fix these problems?

To ensure that your window tint films look and function well, you must take action and fix issues that are starting to surface on them. Here is how you can address the common problems with window tints.


It is usual for air bubbles to form on the tint film after the tint’s installation on the window glass or when it has run its course. Bubbles occur when there is soap, air, water, or dirt present between the car window and dye.

Here is how you can remove the bubbles on your tint:

Step One: Prepare a hairdryer, safety pin, soap, water, spray bottle, and a squeegee.

Step Two: Apply heat to the tint film using a hairdryer. It will help weaken the adhesive and soften the dye, making it easier to manipulate the tint and remove the bubble forming.

Step Three: After exposing the tint to heat, spray soapy water on the area you want to repair. Remember to hydrate the window tint using the solution but avoid getting the tint soaking wet.

Step Four: Gently smooth out the bubbles out of the dye using a squeegee or a hard plastic card.

Hardened Water Spots

Hard water spots form when water evaporates from a surface exposed to heat and leaves behind mineral deposits. These minerals are concentrated such that it is hard to see through them and challenging to remove.

Water spots can obstruct your visuals when driving on the road. These can also be unsightly and bothersome when you want to enjoy the view outside your home.

There are different ways to remove hard water stains on your window tints. Besides using mild window cleaning products, you can also use DIY solutions to clean the windows.

Vinegar Solution Method: Mix equal parts of water and vinegar to make a solution. After making the vinegar solution, you need to spray it directly on the water spots. Allow the water to soak for a few minutes before wiping the area with a soft towel sprayed with the same vinegar solution. Lastly, remove the vinegar solution from the surface using a dry towel or squeegee.

Lemon and Water Solution Method: To apply the lemon juice to the glass window with hard water stains, you need to mix the lemon juice with water. Allow the liquid solution to soak in the water stains for a couple of minutes before removing it using water or traditional glass cleaner. Make sure not to use ammonia-based glass cleaner products.

Toothpaste Method: Water down the toothpaste with water and apply it to the glass using a brush, a towel, or a sponge. Allow the paste to sit for a few minutes before washing it off the glass with water or ammonia-free glass cleaner. Make sure to thoroughly dry the surface to eliminate the chances of water spots reformation.

Baking Soda Method: Mix the baking soda with water to make a cleaning paste. Apply the paste to the glass, and like the other methods, let it sit for a few minutes before removing it using water and glass cleaner.


Like bubble formation, peeling can happen when the window tint is old. Over time, you will notice the films, mainly the corners, beginning to peel away.

The best option when you see your tint peeling is to replace it; however, if you think it is still functioning well and want to keep the tint film for a longer time, there is a way to maintain them and prevent peeling.

Method One: Spray a soapy water solution to the back of the peeling tint film. Afterward, press the tint back against the glass window using a squeegee or hard plastic card. Then, dry it off with a soft, clean cloth. The solution will help the dye to stick back to the glass once dried.

Method Two: Apply heat to the film using a hairdryer. Once the film becomes pliable, remove heat and press the film back against the window.
