How to Remove Tint Glue From Rear Window With Defroster


Defrosters are modes on a car that help melt ice and snow off any automobile window. Using this function, you can easily remove frost or fog from the windows during the cold months of winter. This feature comes standard in most modern cars, but some older vehicles may not have one at all.

How to Remove Tint Glue From Rear Window With Defroster

The defroster setting is usually located on the left side of your vehicle’s instrument panel, and it can be activated by turning a knob or pressing a button. Most defrosters use an electric element to get rid of condensation build-up, but some come equipped with a separate heater. Today I will discuss removing tint glue from the rear window with a defroster.

Step-wise Guide on How to Remove Tint Glue From Rear Window With Defroster

While a tint is applied to the car window to enhance its appearance, people often find trouble removing the glue left behind on other parts, from a challenging area like that of the rear window. A windshield defroster needs to be cleaned well if it remains dirty or gets covered with any stains. It can be done using glass cleaner and water, but many people will think twice before trying such a solution on their defrosters. This problem can also be confronted by those who had used dusting cloths or cleaning agents for wiping purposes without knowing whether they are safe enough or not. Therefore, you should become careful while choosing cleaning products to avoid ruining your defrosters due to an inappropriate removal method. You should also not forget to try the following steps for removing the glue if you have applied a tint on your rear windows.

Step 1:  

Before you start removing the tint, you need to find a solvent for it. An appropriate product can be found in hardware stores. This will help you greatly clean the tough stains left behind by the old adhesive. So, you must clean them well. This step will also ensure proper flow of heat from the defroster towards the windshield. Any dirt may block its channels and prevent effective hot air emission towards the inside of the car.

Step 2:  

First, before pouring solvent directly onto the defroster, you should remove the plastic coating covering it. This can be done using a utility knife or a blade with a sharp edge. Once you remove the plastic coating, make sure to remove every particle of dirt and dust from its surface with the help of a wet cloth, as this may prevent further damage.

Step 3:  

After ensuring that the defroster is completely cleaned, pour some solvent onto it while taking care not to spill any. Let some time pass for its effect on adhesive.

Step 4:  

Now, use a clean cloth to wipe off those small spots left behind if there is no other alternative available except for sandpaper. Ensure that you do not use metal objects like nails, screws, etc., as they may scratch your defroster and reduce the transparency of its surface in some areas.

Step 5:  

Now, wipe off the remaining portion of glue using sandpaper, and be very careful while doing so. This is because scratches may occur if you press hard enough on the defroster with sandpaper or any other metal object. This will end up ruining your defroster and making it totally useless. After cleaning it properly, you should get ready to install a new plastic coating found in auto stores near your locality at affordable prices. It will certainly help you to avoid the trouble of removing tint glue from the rear window with a defroster later on. However, if the problem persists after re-gluing the area, then there is no other option except to remove the tint from the area and apply another new coat.

Step 6:  

Now, put a thick layer of glaze on the cleaned portion and ensure that you use enough quantity for the adhesive to be properly set in its place. Then, give it sufficient time for drying as heat application will help in smoothening out the surface completely. After taking precautions with all these steps, your defroster will be back into its original condition without any problem related to residue left behind by old adhesive, thus ensuring a better flow of air inside your car and keeping occupants cool even in sweltering conditions outside.

Step 7:  

Using this effective method of removing tint glue from the rear window with a defroster will surely prevent further damage. So, once you are done with the application, keep it away from direct touches of hands as this may spoil its surface again.

Step 8:

If you see some minor scratches on the defroster after removing tint glue from the rear window with the defroster, you should not worry about them, as they will certainly fade away over time.

Precautions While Performing How to Remove Tint Glue From Rear Window With Defroster

  • Turn off the A/C compressor at the fuse box or remove the fuse that controls the rear window defroster to avoid burning hands.
  • The tint glue has a solid adhesive quality so that it can harden even after years of removal with water, alcohol, and a heat gun. This is one important thing why you should use chemical solvents such as acetone and methyl ethyl ketone to soften UPVC material under tinted film before manually removing them from window glass by using a razor blade scraper or spatula. 
  • Clear plastic film used for applying car wraps can be removed by simply wiping away with a cloth dampened with lacquer thinner, but Tint Glue cannot be cleaned this way because it is still sticky on the glass even after years of UV exposure.
  • Used bottles of glass cleaners, isopropyl alcohol, acetone, or methyl ethyl ketone are toxic to humans and can be dangerous if you don’t know what solvent it contains and how much is in the bottle. 
  • Never use a sprayer to remove tint glue from glass because broken glass pieces will spread everywhere. Instead, roll down the rear window defroster when removing the film from the window for precise cutting, allowing small shards to go in-between shield molding on vehicle body panels rather than dropping down onto the car upholstery panel when work is done outside body shop premises with dull blades or razor.
  • After removing the old film, make sure that there is no more adhesive before applying the new film.
  • Use gloves and safety glasses when removing tint glue from the window glass with a defroster because the solvent you are using to remove tint film has a strong odor which can create dizziness, vision problem or headache, as well as skin irritation such as redness, swelling, rashes and burn if it touches bare hand or face. 

How To Clean Windshield Haze:

1. Parking in the Sun:

a) If your car has been sitting for a long time and the windows have fogged up, you may be able to get rid of the fog by parking in the sun. Also, put some ammonia in the washer reservoir if it is badly affected.

2. Solve The Problem With An Orange Peel:

Removing the film from your windshield is to rub the orange peel over it with a cloth. This can help you remove any bubbles and cut down on glare while driving at night as well.

3. Remove The Glue And Haze With Windshield Treatment Kit: 

If all else fails, try cleaning the inside of your window with a good auto glass cleaner containing silicone and other chemicals recommended by your car’s manufacturer. You may also try filling a spray bottle with water and adding a teaspoon of toothpaste to the mixture, then using the solution inside your window to remove any haze or adhesive left behind from decals.  

4. A Leaking Heater Core:

A heater core is a duct that transports hot coolant from your engine to your vehicle’s cabin. If it develops a leak, you’ll notice an odor like antifreeze and may hear hissing sounds when you turn on the heat or defroster. The most common reason for this is corrosion in the brass fittings of the core itself. When this happens, water can spray out of these areas and onto your windshield, creating a hazardous situation while driving and damaging your window permanently. Another way this problem could occur is if part of the hoses connecting to the core has become brittle over time due to exposure to extreme temperatures (such as being buried under the snow). Your best bet if either of these situations applies to you is to have your car towed into a shop so it can be properly diagnosed and repaired.

Since the tinted film is no longer popular, I suggest you remove it from a rear window or, when applying a new one, make sure not to choose a dark color because the sun gets in through the corner of the window. But if you really want dark glass, choose a clear film with UV protection that will block 99% of harmful radiation without affecting visibility inside the car and causing potential nightmares, which may occur during summer when hot sun rays are pressing down on your upholstery. I hope you have a clear idea of removing tint glue from the rear window with the defroster. Thank you, and have a nice day!
