Remove the Shattered Glass

When dealing with the broken car window, the very first thing you have to do is to remove the shattered glass. First of all, because it is dangerous and you can scratch yourself by accident if you drive in a car with a smashed window.

So put on thick work gloves, and off we go!

Remove the broken glass pieces that come out from the window frame easily first of all. But be sure you are acting very carefully to avoid injuries!

Sometimes, the car window glass may not be broken fully, and so you will have parts that are pretty hard to get out of the window frame. In this case, to deal with those stubborn shards of glass, feel free to make use of a hammer.

Just tap firmly on them, but make sure you are not acting excessively hard! You don’t want to have pieces of glass all around you in a car!

After all the broken glass is removed, dispose of it in a paper bag. Simply seal the bag tightly with tape and toss it into the trash bin. We do not recommend you use plastic packets for this purpose, by the way, since plastic is too thin.

Broken glass can easily tear it and fall out becoming a hazard for people around if they step on it by accident.

After the broken glass is removed from the window frame and you throw it away to the trash, remember to vacuum all the inside of your car thoroughly. Like this, you will be sure that no tiny piece of glass is left on the seats or on the floor.

Clean the Window Frame

After you take out the broken glass, you need to take care of the busted window’s frame as well before you proceed to apply the protective cover.

Start with wiping the window frame and seal with a damp microfiber cloth to clean away all the dirt and dust.

Afterward, let the window frame and seal air dry completely. But if you are in a hurry, it’s ok if you speed up the process a bit and use a blow dryer, for example, to make everything dry quicker.

Get the Plastic And Tape Ready

Now it is time to proceed to the next step. Measure the length and the width of your car window with a measuring tape. Then, unfold the plastic garbage bag and cut a rectangle to fit your car window (plus about half an inch all around).

You should be able to pull the plastic taut and apply it with a car window tape to the vehicle without having an excessive amount of extra plastic around the edges. That’s because those extras might be tricky to cut off after the temporary car window plastic is attached.

Now cut up eight to ten pieces of masking tape, making sure that each of them is about one to two inches long.

By the way, cutting the plastic bag is easier when it’s done indoors. If you have to do it outside and it’s breezy, gather rocks or other heavy objects to press the bag and prevent it from being blown away.

Tape the Plastic Garbage Bag

To cover the broken car window, you now have to tape the plastic bag. Open the door of your car in order to attach the bag from the inside of the vehicle. Align the plastic to the top inner corner of the car window frame.

Now, apply a piece of masking tape to the plastic bag and the car window frame, placing the tape underneath the rubber window seal. Pull the plastic taut and adhere it to the top outer corner with the use of a piece of masking tape, placing the tape underneath the rubber window seal.

Adhere one or two more pieces of masking tape along the top of the window in order to secure the plastic. Then, pull the plastic taut and adhere it to the bottom inner corner of the window frame with a piece of masking tape.

Pull the plastic taut and adhere it to the bottom outer corner of the car window frame with the use of a piece of masking tape. Now, attach one or two more pieces of tape along the sides of the window to secure the plastic.

Finally, attach one or two more pieces of tape along the bottom part of the window to secure the plastic.

You might also want to make use of duct tape for securing the plastic along the bottom if the masking tape does not adhere well enough. But we would not recommend you use it exclusively. See, duct tape tends to damage the car paint when you peel it off the frame!

Create the Seal

Finally, it is time to create the seal. Cut six to eight long pieces of masking tape, enough to go around the entire window perimeter. Attach the tape around the plastic to secure the first layer of tape and create a seal to keep out water and air.

In case you see that the masking tape you are using is not strong enough, it’s ok to make use of duct tape for the bottom seal.

With such a detailed and precise guideline, you will be able to create a protective plastic cover for your car’s broken window. Of course, such protection is not meant for being there all the time!

The second you have enough time and money, bring your car to the service center to have the breakage repaired. But if you do everything right according to our instructions, you can be sure that this plastic cover will last long enough.

Those bags are made of resin which means that they don’t tear easily. Besides, they are clear which allows you to see at least something through the cover while driving.

Low-density garbage bags (like those we use in our kitchens) will not be a proper substitution. However, if you have no choice and your car’s broken window must be fixed right now, they can also be used.

Only remember not to drive fast or far with the window cover made of kitchen garbage packets! They don’t allow the same good visibility as high-density bags which may lead to accidents on the road.

With this list at hand, you will easily pick up the necessary tools and supplies to make your own protection for the broken car window.
