You may question how to remove mold from wallpaper if you’ve noticed mold growing on the walls of your home. For a long period of time, your wallpaper may be covered in mold or mildew.

While eradicating mildew from wallpaper isn’t difficult in most cases, taking action as soon as you notice a problem is critical. Even the most beautiful wallpaper might turn into an eyesore if these imperfections aren’t fixed.

Depending on how much mold spores have grown, you may not be able to remove them from wallpaper altogether. If you can figure out how the mold is spreading, you can stop it from happening again.

Warm, moist environments favor the growth of mold and mildew. That’s why maintaining a constant amount of indoor humidity is so important.

If you live in a wet location, a dehumidifier can help keep your home dry.

The most obvious sign of a mold problem is the discovery of green, brown, orange, or even black spots. But there are also less obvious indicators:

  • Paint that has peeled or cracked.
  • Discoloration
  • “Soot” and other dark splotches that appear repeatedly
  • Continually expanding
  • Smells damp and musty.

How Do You Remove Mold From Wallpaper?

The first step is to make a cleaning solution of 1 cup water and 1/2 cup distilled white vinegar in advance of cleaning time. Fill a spray bottle or a bucket halfway with this solution.

One drop of tea tree oil in a cup of water can be used to make a cleaning solution that works.

Step 2: Spray the solution onto a clean sponge, dip it into the container, and wring out as much liquid as possible before disposing of it. Protect your hands by using gloves while cleaning the walls.

Using a sponge, gently scrape away any remaining mold residue from the molded surface. The solution should be tested in an undetectable spot to ensure that it does not ruin your wallpaper.

In a corner or behind a doorway, you could try. If there is no damage to the wallpaper, then you may continue with the installation.

Make little circles with the sponge instead of saturating the wallpaper. It shouldn’t be completely drenched, but it shouldn’t be dry either.

Wipe off the wall with a soapy sponge soaked in fresh water and a soft cloth, then rinse. Allow the wall to air dry before re-washing it.

Use as little substance as possible to dampen the area without causing drips. Don’t stop working until the mold is gone!

Avoid bubbles by not letting your wallpaper get too moist while cleaning. Dry the area completely once you’ve removed all mold spores from it.

As long as there is visible dampness on the walls, remind family members to keep a window open or a fan running.

What Are The Negative Effects Of Mold?

Mold and mildew can cause a variety of problems, ranging from a little irritation to a major structural concern requiring costly repair work. Even better, it’s frequently an issue of proper circulation and sunlight, rather than a major architectural concern.

Insufficient plumbing, poor weather resistance, or increased moisture are only severe causes of these issues. You may need intrusive wet proofing methods if you have growing damp as a result of substandard construction.

In some circumstances, it may be necessary to remove the floors and look within the walls. Additionally, the fungal spores might induce respiratory issues such as asthma or allergies.

Is It Mold Or Mildew?

Fungi such as mold and mildew grow in moist environments with little air circulation. Condensation, humidity, and water leaks are the most typical sources of mold and mildew on walls.

Mildew has a powdery appearance and is typically gray or white in color. In damp environments, it’s common to find it laying on flat surfaces. Due to mildew’s nature as a surface mold, it will not harm the structure of your home

Spores in the air carry mold spores, which spread the fungus around. Black, yellow, or green in color, with a fuzzy or slimy texture, is the most common color. The presence of mold in your home can lead to structural problems as well as health problems.

Signs of Mold on Walls

An interior wall can be infested with mold at any point. However, you’re more likely to find it near the ceiling or floor, or along the baseboard trim. The bathroom is the most usual place to find it, but it can also occur in the kitchen, the laundry room, the basement, and other places with poor ventilation.

Signs that your home is infested with mold include:

  • A wet or musty odor is seen as unpleasant.
  • Paint that is flaking and cracking.
  • Your walls or ceiling are covered in visible mold spores.
  • Indoors, my allergy issues intensified.

Even a small area of mold development on the walls of your home should be addressed right away. Unless you eliminate the mold soon, it will spread and become detrimental to your property and your health if you don’t do so.

Exposure to mold can induce allergic reactions and ill health, according to research. Runny nose, itchy eyes, and difficulty breathing are all possible symptoms. If you see any evidence of mold, it is imperative that you take action immediately.

How to Get Rid of Mold On Walls

Mold on walls may usually be removed by oneself if only a small area is affected. Various household items can be used. Borax, vinegar, baking soda, tea tree oil, bleach, and hydrogen peroxide are some of the most popular and effective alternatives.

When the mold is severe and widespread, it’s not as simple to get rid of. In fact, attempting to remove it yourself could result in serious injury or death. If you have mold in your house, we recommend that you hire a mold removal professional.

Mind Your Own Business

In order to get rid of mold on walls, there are two main actions that must be taken. In order to get rid of mold, you’ll first have to figure out how to keep your home dry.

1. Identify the Cause of the Mold

In order to remove mold from walls, this is the first and most critical step. To avoid a recurrence of mold, you must locate the source of the problem and resolve it.

Getting rid of the mold requires correcting any water damage (such as leaks) and managing the amount of moisture in your home.

2. Prepare Your Room and Clean the Walls

To begin eliminating mold from the walls, you must first clear the space. Remove all furniture, textiles, and electrical devices from the area. Then, use plastic sheets to protect the floor.

After that, scrub the afflicted area with a damp sponge dipped in dishwashing solutions.

You should wear safety gear before you begin cleaning or treating the wall with any product. You can protect yourself against mold exposure by wearing safety goggles, rubber gloves, and a face mask. You should also open the windows and doors while you are eliminating mold.

3. Remove the Mold

A little spot of mold on painted interior walls is most likely to be on the surface. Household cleaners should be able to get the job done. Options include items like borax, white vinegar, baking soda, or tea tree essential oil..

Is the mold patch confined to a non-porous (painted or sealed) wall? As a result, we advise that you begin by utilizing a natural mold remover.

But what if you have a vast area of mold? Or is it possible that natural mold removers fall short of the mark? Chemical cleaners with more power may be more appropriate in this situation. Purchase this online or at a home improvement shop.

Porous materials like cement, concrete, or stone provide a breeding ground for mold. It can also spread from room to room.

When it comes to dealing with mold on a porous (unsealed) wall, hydrogen peroxide and distilled white vinegar are the most effective solutions.


One cup of borax to one gallon of boiling water in a container. Shake well to disperse the borax before using. Spray the afflicted area with the solution from a spray bottle.

With a brush, remove the mold off the wall, then wipe it clean and let it dry. The solution does not need to be rinsed off. If the source of the mold problem has been addressed, the borax will assist to keep the mold from returning.

Vinegar and Baking Soda

Mold may grow on porous or non-porous walls alike, and vinegar is a safe and effective approach to get rid of it. White vinegar has been demonstrated to kill 82% of mold spores. It is said to penetrate porous materials and kill the mold at the root.

Using a spray bottle, add some white distilled vinegar. Leave the vinegar on the wall for an hour after spraying. Then, using a sponge and warm water, thoroughly clean the affected area.

To remove mold, you may need to scrub the wall with vinegar. We propose making a baking soda solution for this.

Natural disinfectant Baking soda can be used to remove mold. In addition, it deodorizes and removes the musty, moldy odor that mold can generate. Finally, it wicks away moisture, preventing the growth of mold.

One teaspoon of baking soda and two cups of water in a spray bottle are all you need to make a baking soda solution. Shake thoroughly before using. Use a scouring pad or a brush to scrub away the mold after applying the solution.

Remove any remaining mold from the surface by rinsing with warm water. Spray the wall one last time with the vinegar or baking soda solution to ensure that all of the mold has been removed.

Tea Tree Oil

The antifungal and antibacterial qualities of tea tree essential oil make it an excellent mold removal remedy (5). To begin, fill a spray bottle with two cups of water and one teaspoon of tea tree oil. Wipe away the mold with a clean cloth sprayed with the solution.

Rinsing is unnecessary because the tea tree oil kills mold and prevents it from returning to the surface. Mold and mildew can be removed from painted and wallpapered walls with this procedure.

Grapefruit Seed Extract

One of the best natural mold killers is the extract from the seeds of grapefruit. Mold is naturally killed by the grapefruit’s citric acid. As a disinfectant and deodorizer, it is also useful.

Spray a solution of 10 drops of grapefruit seed extract to one cup of water into a spray bottle. Spray the solution into the afflicted region after shaking the bottle completely. Wipe away the mold and solution with a clean cloth after a few minutes.

Grapefruit seed extract can be used for a longer period of time to kill mold and prevent its recurrence. To keep it from growing back, you may want to repeat this procedure every two to three days.

Using bleach to remove mold from non-porous surfaces is an effective method. To kill roots, it must penetrate porous surfaces. However, before you begin cleaning, be careful to test a small area of the wall with some of the bleach solutions. As a result, the finish is protected.

Mix one part bleach with three parts water, then apply the solution to the wall. After a ten-minute wait, use a brush to remove any mold that has formed. Use a clean towel to wipe the area down and then rinse it with clean water to remove any residue.

Hydrogen Peroxide and Vinegar

In addition to its antifungal, antiviral, and antibacterial properties, hydrogen peroxide also works wonders on mold. As with bleach, hydrogen peroxide can be used to eradicate mould without producing hazardous fumes or leaving behind poisonous residue when coupled with distilled white vinegar, making it a more effective and safe option.

Effervescent qualities also make it a better choice for destroying mold on porous surfaces than bleach. It is possible to employ hydrogen peroxide on both porous and non-porous surfaces. ‘

Spray the afflicted region with 3 percent hydrogen peroxide, undiluted, in a spray bottle. For best results, let the mold sit on the surface for 10 to 15 minutes before using a brush to scrub it off the walls.

Types of Wall

Depending on the type of wall you have, the optimal mold removal method may differ slightly.

  • Porous and visible just on the top layer of the drywall is where mold thrives. A vinegar solution can be used instead of bleach. If the mold reappears, the only remedy is to replace the drywall because it’s too deep in the layers. When it comes to mold-resistant drywall, there’s good news:
  • Brick and concrete are both permeable materials. Vinegar or hydrogen peroxide are the greatest options because they kill the mold from the inside out. Scrub vigorously with a brush to remove all molds.
  • For cinder block walls, the first step is to thoroughly clean the wall. Then, apply the solution of your choice and scrape with a brush to remove the dirt. Remove any remaining mold growth, then reapply the solution and let it set for up to 20 minutes. Lastly, make sure that the wall is completely dry so that mold does not grow on it again.
  • Wallpaper: Tea tree oil, grapefruit seed extract, or vinegar are the best remedies for mold on wallpaper. Dip a sponge into the solution and wring it out to avoid harming the wallpaper. Remember to try the product in an unnoticeable location first! Remove the mold by gently rubbing in circles without wetting the wallpaper.
