Mold, or mildew, is a type of fungus that thrives in damp environments, growing in moist and humid areas within your home. It can often be found in spaces like basements, bathrooms, kitchens, or places affected by leaks. The presence of mold is not just an eyesore but can also pose serious health risks, especially for individuals with allergies or respiratory issues. Mold exposure can lead to asthma, allergic reactions, skin irritation, and breathing difficulties.
In fact, research estimates that 10% to 50% of homes worldwide suffer from significant mold issues. The good news is, that there are several ways to tackle this problem, and one common household product—hydrogen peroxide—may be an effective solution for eliminating mold.
If you’re dealing with mold in your home, keep reading to learn about the role hydrogen peroxide can play in mold removal, when to use it, and when it might be better to call a professional. For immediate assistance, don’t hesitate to contact PNW Restoration at (971) 247-3381.
What Is Mold and Why Is It Harmful?
Mold is a type of fungus that grows in dark, damp, and humid environments. Mold reproduces through tiny spores that float in the air and can settle on surfaces, especially where moisture is present. It feeds on organic materials like wood, paper, and fabric, causing them to deteriorate over time.
While some mold is harmless, exposure to mold spores can trigger a range of health issues, including:
- Asthma attacks: Mold spores can irritate the respiratory system, making asthma worse.
- Allergy symptoms: Mold exposure can lead to sneezing, coughing, a runny nose, and itchy eyes.
- Breathing difficulties: People with weakened immune systems or respiratory conditions may experience difficulty breathing.
- Skin irritation: Direct contact with mold can cause rashes or other skin reactions.
Therefore, it is crucial to address mold growth as soon as possible to prevent these issues. If mold is left untreated, it can cause structural damage to your home, especially to porous materials like wood and drywall.
Can Hydrogen Peroxide Kill Mold?
Hydrogen peroxide is well known for its disinfecting properties. Commonly used to clean wounds, hydrogen peroxide is a powerful antiseptic that kills bacteria, viruses, fungi, and mold spores.
How does hydrogen peroxide kill mold?
When applied to mold, hydrogen peroxide works by breaking down the essential components of the microorganisms, including their proteins and DNA. This causes the mold cells to break apart, effectively neutralizing the threat.
Several studies have found that hydrogen peroxide can inhibit the growth of common household fungi. A 2013 study tested hydrogen peroxide’s ability to fight mold and concluded that it could effectively inhibit fungal growth on solid surfaces. However, it may not be as effective on porous surfaces, where mold spores can penetrate deep into the material.
When Can Hydrogen Peroxide Be Used to Remove Mold?
Hydrogen peroxide is particularly effective for removing mold from non-porous surfaces. Non-porous surfaces, such as:
- Counters
- Glass
- Tile surfaces
- Bathtubs
- Shower walls
These surfaces are ideal for mold removal with hydrogen peroxide because the mold spores only affect the surface layer. For porous surfaces like wood, drywall, and fabric, hydrogen peroxide may not be able to reach the mold’s roots, so the surface may need to be replaced.
If you’re dealing with mold in your home, (971) 247-3381 is the number to call for fast, reliable mold removal services.
When Hydrogen Peroxide May Not Be Enough
While hydrogen peroxide can effectively eliminate surface-level mold, it may not work well on porous surfaces. When mold penetrates deep into materials like wood, ceiling tiles, drywall, or carpets, it can be difficult to remove completely. In these cases, professional mold remediation services may be necessary to fully eliminate the mold.
If you suspect mold has infiltrated your walls or other porous materials, or if you notice large patches of mold (more than 10 square feet), it’s best to call in experts for the job. Reach out to us at (971) 247-3381 for professional mold removal and remediation services.
How to Use Hydrogen Peroxide to Kill Mold
If you decide to tackle mold removal yourself, follow these simple steps to use hydrogen peroxide effectively:
Materials Needed:
- 3% hydrogen peroxide (the kind you typically find in drugstores)
- Spray bottle
- Soft brush or rag
- Protective gloves, goggles, and mask
Step-by-Step Instructions:
- Prepare the Solution: Pour the 3% hydrogen peroxide into a spray bottle. No dilution is necessary for this solution.
- Spray the Affected Area: Spray the moldy surface generously with hydrogen peroxide. Be sure the surface is fully covered.
- Let It Sit: Allow the hydrogen peroxide to sit on the surface for about 10 minutes. You’ll notice some bubbling as it works to break down the mold.
- Scrub the Surface: After the solution has sat for a while, take a soft brush or rag and gently scrub away the mold. Start with light scrubbing and increase the pressure if necessary.
- Wipe and Dry: Once the mold is removed, use a clean, dry cloth to wipe the surface dry.
- Repeat if Necessary: If mold persists, repeat the process until the surface is clean.
Important Tips:
- Always wear gloves, goggles, and a mask when dealing with mold.
- Test the hydrogen peroxide on a small, inconspicuous area first to ensure it doesn’t damage the surface.
- Make sure the area is thoroughly dried after cleaning to prevent mold from returning.
Why Hydrogen Peroxide Is a Good Option for Mold Removal
Hydrogen peroxide is a safer, more natural alternative to harsh chemicals like bleach. It is non-toxic, eco-friendly, and breaks down into water and oxygen, making it a great choice for people who are sensitive to chemicals.
Unlike bleach, hydrogen peroxide doesn’t release toxic fumes, making it safer for individuals with respiratory conditions, asthma, or allergies.
Where NOT to Use Hydrogen Peroxide for Mold Removal
Although hydrogen peroxide is effective on many surfaces, there are certain places where it should not be used.
- Porous Surfaces: As mentioned, hydrogen peroxide doesn’t penetrate porous materials like wood, drywall, or fabric. If mold has infested these surfaces, replacement may be necessary.
- Colored Fabrics: Hydrogen peroxide has bleaching properties, so it may discolor fabrics, particularly natural ones like wool. If you use hydrogen peroxide on fabrics, test it on an inconspicuous area first.
Alternatives to Hydrogen Peroxide for Mold Removal
If hydrogen peroxide doesn’t work for your specific mold problem, there are other natural alternatives you can try:
1. Vinegar
Vinegar is another common household product used for mold removal. It is effective on many surfaces and can kill up to 82% of mold species. Simply spray undiluted white vinegar on the mold and let it sit for an hour before scrubbing.
2. Baking Soda
Baking soda is mild and safe for both porous and non-porous surfaces. Mix one tablespoon of baking soda with a cup of water and spray it onto the mold. After a few minutes, scrub the area and rinse.
3. Tea Tree Oil
Tea tree oil contains antimicrobial properties that are effective against mold. Mix a teaspoon of tea tree oil with a cup of water and spray it directly onto the affected area.
4. Grapefruit Seed Extract
Grapefruit seed extract is another natural option. Mix 10 drops of the extract with a cup of water and spray it onto the moldy surface.
5. Bleach
Although harsh, bleach can effectively kill mold on non-porous surfaces. Use it sparingly and ensure proper ventilation when using bleach to avoid harmful fumes.
