DIY Mold Remover Recipes to Get Rid of It for Good

Mold can be a real nightmare to deal with, both for your home and your health. I’ve moved into homes with mold problems, and it caused me respiratory problems I’m not sure I ever got over completely. But you can tackle mold with a number of simple pantry staples.

Whether it’s creeping up in the corners of your bathroom, lurking in the damp areas of your basement, or spreading across your window sills, mold is that unwelcome guest you want to get rid of ASAP.

The good news is, you don’t have to rely on harsh chemical cleaners to tackle mold. In fact, there are several simple, natural DIY mold remover recipes you can make at home using common household ingredients.

Not only are these homemade solutions more eco-friendly, but they can be just as (if not more) effective at getting rid of mold and preventing it from coming back. Let’s take a look at some of the best DIY mold remover recipes, as well as the science behind why these natural ingredients are so powerful against mold.

Why Is Mold a Problem?

Mold isn’t just gross to look at – it can also pose serious health risks. It’s been linked to a range of respiratory issues, from coughing and wheezing to more severe conditions like asthma and lung infections. Mold can also trigger allergic reactions and irritate your skin, eyes, and nasal passages.

And beyond all those health concerns, mold can also cause significant structural damage to your home if left unchecked. As the mold colony grows, it can penetrate and weaken building materials like wood, drywall, and insulation. This can lead to costly repairs down the line.

That’s why it’s so important to address mold problems quickly and effectively. DIY mold remover solutions can be a great way to tackle the issue without breaking the bank or exposing yourself to harsh chemicals.

What Household Ingredients Destroy Mold?

There are a lot of different kinds of molds and different surfaces in your home. What works on one mold spot may not work on the next. But here are some of the ingredients that actually do work, with explanations of what they can and can’t do.

Vinegar

The acetic acid in vinegar is the key to its mold-fighting power. Acetic acid disrupts the cell walls of mold spores, causing them to break down and die. It’s a highly effective broad-spectrum fungicide that can get rid of up to 82% of mold species.

Baking Soda

Baking soda, or sodium bicarbonate, works in a few different ways to combat mold. First, it has mild abrasive properties that help physically scrub away mold growth. Additionally, baking soda is a mild alkali that can raise the pH level of the affected area, creating an environment that isn’t hospitable for mold. That discourages it from coming back.

Hydrogen Peroxide

Hydrogen peroxide is a powerful oxidizing agent that can effectively destroy mold spores. When it comes into contact with mold, the hydrogen peroxide molecule breaks down into water and oxygen. This process releases free radicals that damage the cell walls and DNA of the mold, causing it to die off.

Tea Tree Oil

Tea tree oil contains a variety of potent antifungal compounds, including terpinen-4-ol and alpha-terpineol. These compounds work to disrupt the cell membranes of mold spores, causing them to rupture and die. Tea tree oil has been shown to be effective against a wide range of mold species.

Borax

Borax, or sodium borate, works against mold in a few key ways. First, it’s a mild alkali that can raise the pH level of the affected area, making it inhospitable for mold growth. Borax also has natural antifungal properties that can directly destroy mold spores. Additionally, it helps to absorb moisture, which is essential for preventing mold from returning.

DIY Mold Remover Recipes

Vinegar-Based Mold Remover

One of the most popular and effective DIY mold removers is a simple vinegar-based solution. As we said above, vinegar is a powerful natural disinfectant that can get rid of up to 82% of mold species. I’ve had great results with it many times.

Here’s how to make it:

Ingredients:

• 1 part white vinegar
• 1 part water

Instructions:

1. Mix the vinegar and water in a spray bottle.
2. Spray the affected area liberally, making sure to get into all the nooks and crannies where mold may be hiding.
3. Let the solution sit for at least an hour before wiping it away with a clean cloth.
4. Repeat the process as needed until the mold is fully removed.

The acetic acid in the vinegar is what makes this solution so effective against mold. It works by disrupting the mold’s cell structure, causing it to die off. The water helps dilute the vinegar and makes it easier to apply.

Baking Soda and Hydrogen Peroxide Mold Remover

If the vinegar doesn’t get rid of mold for good, another powerful DIY mold remover combines the cleaning power of baking soda with the disinfecting properties of hydrogen peroxide.

These are both amazing cleaners on their own.

SAFETY NOTE: don’t store this mixture! Make a batch and use it right away, or it could become toxic. Also use gloves when applying this recipe. It can be very harsh on skin. You only want it to be harsh on the mold.

Ingredients:

• 1 cup baking soda
• 1 cup hydrogen peroxide (3% solution)
• Spray bottle

Instructions:

1. Mix the baking soda and hydrogen peroxide in the spray bottle until a paste-like consistency forms.
2. Spray the paste directly onto the moldy areas, making sure to cover the entire affected surface.
3. Let the solution sit for at least 15 minutes before scrubbing with a brush or sponge.
4. Rinse the area thoroughly with water and dry completely.

The baking soda in this recipe acts as a gentle abrasive, helping to lift and remove the mold growth. Meanwhile, the hydrogen peroxide disinfects and gets rid of the mold spores. Together, these two ingredients create a powerful one-two punch against mold.

Tea Tree Oil Mold Remover

Tea tree oil is another natural mold fighter that you can use to create a DIY mold remover. This essential oil has strong antifungal and antibacterial properties that make it highly effective against mold.

Ingredients:

• 1 cup water
• 2 tablespoons tea tree oil
• Spray bottle

Instructions:

1. Mix the water and tea tree oil in the spray bottle.
2. Spray the solution directly onto the moldy areas, making sure to cover the entire affected surface.
3. Let the solution sit for at least 30 minutes before wiping it away with a clean cloth.
4. Repeat the process as needed until the mold is fully removed.

The active compounds in tea tree oil, such as terpinen-4-ol and alpha-terpineol, are what give it its potent antifungal properties. These compounds work to disrupt the cell membranes of mold spores, causing them to break down and die.

Borax Mold Remover

Borax is another natural mold-fighting ingredient that you can use to create a DIY mold remover. It’s a mineral compound that has powerful disinfecting and deodorizing properties.

Ingredients:

• 1 cup borax
• 1 cup water
• Spray bottle

Instructions:

1. Mix the borax and water in the spray bottle until the borax is fully dissolved.
2. Spray the solution directly onto the moldy areas, making sure to cover the entire affected surface.
3. Let the solution sit for at least 30 minutes before scrubbing the area with a brush or sponge.
4. Rinse the area thoroughly with water and dry completely.

Borax works by creating an inhospitable environment for mold to grow. It raises the pH level of the affected area, making it too alkaline for mold to thrive. It also has the added benefit of helping to eliminate any musty odors that may be associated with the mold.

Usage Tips

1. Identify and Address the Root Cause: Before you start scrubbing away at the mold, it’s important to identify and address the underlying cause of the mold growth. This is usually excess moisture or humidity in the affected area. Make sure to fix any leaks, improve ventilation, or use a dehumidifier to address the root cause.
2. Prepare the Area (and yourself): Be sure to wear protective gear, such as gloves, goggles, and a mask, when working with mold. Also, cover any nearby surfaces or furniture to prevent the mold spores from spreading.
3. Start with a Small Test Area: Before applying the DIY mold remover to the entire affected area, do a spot test in a small, inconspicuous area. This will help you ensure the solution doesn’t damage the surface or leave any staining.
4. Agitate the Surface: When applying the DIY mold remover, be sure to scrub the affected area with a brush or sponge. This will help loosen and lift the mold, making it easier to remove.
5. Rinse Thoroughly: After letting the solution sit for the recommended time, be sure to rinse the area thoroughly with clean water. Any leftover mold or cleaning solution can provide a food source for new mold growth.
6. Dry the Area Completely: Mold thrives in damp environments, so it’s essential to make sure the area is completely dry before considering the job done. Use fans, dehumidifiers, or open windows to facilitate proper drying.
7. Monitor for Regrowth: Even after successfully removing the mold, continue to monitor the area for any signs of regrowth. If you notice mold starting to come back, repeat the cleaning process as needed.
