How To Remove Headliner Glue And Foam Residue? (Explained)

After removing your car’s headliner, there’s a huge chance that some glue and foam will be left behind. It’s not usually very easy to remove the entire headliner without leaving behind some residue.

This is because the headliner is designed to adhere firmly to the roof of your car, and it’s not meant to be removed.

Whether you intend to leave the roof headliner-free or install some new headliner, you must get rid of this residue without damaging the roof.

Headliner residue is usually very stubborn. It doesn’t come off easily, not unless you use a solvent or strong cleaner.

Even though these products do an excellent job of removing headliner glue and foam residue, you have to be very careful when using them since they can easily spill onto the upholstery and bleach the fabric.

If you have just removed your headliner and are struggling with getting the residue off, in this article, we will list some of the products you can use and techniques that can help you get rid of headliner residue.

how to remove headliner glue and foam

1. 3M Adhesive Remover

Out of all the products that people use to remove headliner glue and foam, none beats 3M Adhesive Remover. If you have used 3M products, you are well aware of how effective their products usually are.

3M adhesive remover dissolves the glue sticking the foam residue to the surface. If you leave it on for some minutes, it completely strips off any adhesive on the roof, thus making it easy for you to clean off any residue left behind.

You can get a 3M adhesive remover in an auto store near you. This product has got tons of positive reviews regarding its ability to remove headliner glue and foam.

Therefore, if you have tried scraping the headliner residue with a blunt object and it’s not working, you should give 3M adhesive remover a chance.

2. Lacquer Thinner

For some reason, if you cannot get your hands on 3M adhesive remover, you can always use lacquer thinner. This product is a powerful solvent.

It works in minutes, and it’s very effective at removing the residue from your headliner. In cases where you are dealing with stubborn headliner glue and foam, lacquer thinner can save the day.

Because you are removing residue on top of the car, you may want to cover the seats with a cloth so that lacquer thinner doesn’t drip and stain the seats.

Another pro tip is to soak lacquer thinner on a sponge and scrub it against the roof. Some people put lacquer thinner in a spray bottle. However, this technique has its risks because droplets of lacquer can spread to car upholstery.

3. Acetone

When it comes to stubborn stain removers, it’s impossible not to find acetone on the list. Acetone can dissolve even the strongest adhesive products.

If you have some acetone lying around, get some in a spray bottle, and you can use it alongside a wire brush. After a few minutes, you should be done with removing glue and foam residue from your car roof.

4. Isopropyl Alcohol

If acetone fails, then you can try isopropyl alcohol. This is another famous stain remover. It is effective and works within minutes.

Isopropyl alcohol dissolves the adhesive holding the foam to the roof. When that happens, the residue comes off without much scrubbing.

Can Goo Gone Remove Headliner Residue?

Goo Gone has been used in the auto industry for many years. It is an excellent stain remover. Unfortunately, Goo Gone lacks the ability and strength to remove headliner glue and foam.

The adhesive on headliners is usually too strong for Goo Gone. However, if you have some lying around, it’s worth giving it a shot.

Can a Scotch-Brite Pad Help?

A Scotch-Brite pad can act as an adhesive. It can complement the effects of the above products, such as lacquer thinner and 3M adhesive remover.

What this product does is agitate the headliner residue. As a result, it comes off quickly. Instead of a Scotch-Brite pad, you can always use sandpaper.

It will serve the same purpose. There is another excellent option if you are struggling with removing headliner residue, and that is a wire brush.

It also comes off very easily when you rub off the headliner glue and foam with a wire brush.

Is It a Must for Me to Remove Headliner Residue?

This will depend on what you intend to do next. If you want to put another headliner, you must remove some of the headliner residues, even if it’s not all.

Leaving behind some headliner residue can cause the new one not to hold on better and for longer. Therefore, you must clean the residue until it’s almost done.

The other reason could be you want to convert the car into a race or show car, which may not require the installation of another headliner.

In this case, you can’t leave behind headliner residue because the vehicle will look ugly. You need to look for the ideal solvent and get to work. Yes, it may require several attempts and can use up a considerable amount of your time.

But the final results will be worth it. You need to use a suitable solvent. This will save you a lot of time, stress, and effort.

Tips on How to Safely Remove Headliner Glue and Foam Residue

As you go through the list of ingredients that we have been recommending above, you may realize that most of them are toxic and harsh chemicals.

If you are not careful, they can get inside your nose and eyes, causing irritations. Or, they can spill on the car upholstery and result in bleaching or stubborn stains.

So, here are some tips that will ensure you safely remove headliner residue;

  • Always wear a respirator mask

Unless you are using ordinary soap and water to remove the headliner residue. Always wear a mask. Breathing in acetone or paint thinners is risky to your health. And since you are working on the roof of the car, it’s very easy for you to get some of these ingredients on your face.

  • Cover your car upholstery with a thick cloth

Some of these ingredients are corrosive and may bleach your car seats or dash. Ensure that the upholstery is covered using a thick cloth to prevent that from happening.

  • Scrape the roof gently

Unlike other parts of your car, the roof often features a thin sheet of metal. Understandably, removing headliner residue may need a lot of elbow grease.

In the process, you may end up treating the roof very roughly. This can lead to damage, especially if you are using a sharp and pointed scraper. It’s important to be as gentle as possible.

How Long Does It Take to Remove Headliner Residue?

Two factors will determine this; the size of your car’s roof and the product you are using. If you are working on a bigger area, it will take longer compared to working on a vehicle with a small roof.

Secondly, the product you are using also matters. If you are using something as effective as 3M adhesive remover, it should take a shorter time than soap and water to remove headliner residue.

Regarding the first factor, there isn’t much we can do about it. However, the second factor can be altered. Using a stronger solvent, should absorb into the headliner adhesive and weaken it.

This should speed up the process compared to a cleaner that doesn’t have the strength to dissolve into adhesive.

When you use a strong solvent, it should take you an hour to clean the headliner of a saloon or equally sized car. If it’s an SUV, it may probably take an hour and a half or two hours.

If you can get an extra set of hands to help, it will take half that period. So, the more, the merrier.

Why Is It Difficult to Remove Headliner Glue and Foam?

The main reason it’s hard to remove headliner glue and foam is that it has been there for a while.

Headliners often start to show signs of wear after five or six years. That’s a long time for a material to be glued to another surface. You shouldn’t be surprised when you are left with residue behind after removing the headliner.

The other reason why headliner residue is hard to come off is that auto manufacturers use quality glue when sticking headliners.

Unlike most glues found in stores nowadays, auto manufacturers use industry-standard adhesive to ensure the headliner remains fitted to the car roof for years.

Considering the strength of this glue, it shouldn’t come off easily. And its residues can only come off with the help of a solvent.

Can Water Remove the Headliner Glue and Foam?

If you are cautious about the solvents mentioned above, you can give water a try. Soapy water, to be precise, can remove headliner glue and foam, but this should take a while.

Soap and water aren’t as strong as the solvents we have listed. Therefore, it should take a lot of time for the soapy water to absorb into the foam and glue.
