🛒 What You Need
- Rubber gloves
- N95 respirator mask
- Safety goggles
- Old clothes/disposable coveralls
- Spray bottle
- Stiff-bristled brush or scrub sponge
- White distilled vinegar
- Hydrogen peroxide (3%)
- Baking soda
- Clean cloths or old rags
- Fan or dehumidifier
- Heavy-duty trash bags
📋 Steps
Assess the Mold and Prioritize Safety
Before you begin, carefully assess the extent of the black mold. This guide is for small, manageable areas (less than 10 square feet). Put on your N95 respirator mask, safety goggles, and rubber gloves to protect yourself from mold spores and cleaning solutions. Ensure the area is well-ventilated by opening windows and using fans to direct air outwards.
Identify and Fix the Moisture Source
Mold cannot grow without moisture. It's imperative to find and fix the source of the dampness, whether it's a leaky pipe, condensation, or poor ventilation. Cleaning the mold without addressing the underlying moisture problem will only lead to its return. This step is critical for long-term mold prevention.
Choose Your Cleaning Solution
For non-porous surfaces, white distilled vinegar is an excellent natural fungicide. Fill a spray bottle with undiluted white vinegar and spray it directly onto the moldy area. For more stubborn mold or porous surfaces like drywall (if removal is not an option), a 3% hydrogen peroxide solution can be effective. Alternatively, a paste of baking soda and water can be used for scrubbing.

Apply and Scrub the Mold Away
Allow your chosen cleaning solution to sit on the mold for at least 10-15 minutes to penetrate the spores. Then, use a stiff-bristled brush or scrub sponge to thoroughly scrub the mold from the surface. For porous materials, be gentle to avoid further damage. Ensure you cover all visible mold and surrounding areas.
Rinse and Dry Thoroughly
After scrubbing, use a clean, damp cloth to wipe away any residual mold and cleaning solution. It's crucial not to leave any moisture behind. Use a fan, dehumidifier, or open windows to dry the area completely as quickly as possible. Proper drying is key to preventing immediate re-growth.
Dispose of Contaminated Materials
Carefully place all used rags, brushes, and any other contaminated materials into heavy-duty trash bags. Seal the bags tightly before disposing of them outside your home. This prevents the spread of mold spores to other areas of your house. Clean any reusable tools thoroughly with a disinfectant.
Prevent Future Mold Growth
Maintain good ventilation in your home, especially in moisture-prone areas like bathrooms and basements. Fix leaks promptly, use exhaust fans, and consider a dehumidifier in humid environments. Regularly inspect areas prone to mold growth and address any signs of dampness immediately to prevent recurrence.
💡 Tips & Tricks
- Always test your cleaning solution on an inconspicuous area first to ensure it doesn't damage the surface.
- Improve air circulation by opening windows, using fans, and ensuring furniture isn't blocking vents.
- Consider applying mold-inhibiting paint in areas prone to dampness after cleaning and drying.

❓ Frequently Asked Questions
How do you get rid of black mold on walls?
To remove black mold from walls, ensure the area is dry and well-ventilated. Apply a solution of undiluted white vinegar or a 3% hydrogen peroxide spray, let it sit for 10-15 minutes, then scrub with a stiff brush. Rinse with a damp cloth and dry completely with a fan.
What's the best way to get rid of mold in a basement?
Getting rid of mold in a basement starts with addressing the moisture source, such as leaks or high humidity. For small areas, clean with vinegar or hydrogen peroxide, ensuring good ventilation. For extensive basement mold, especially on porous surfaces, professional remediation is often necessary.
How do you get rid of mold smell after cleaning?
To eliminate mold smell, ensure the cleaned area is completely dry, as residual moisture can perpetuate the odor. Use a dehumidifier and fans for several days. Baking soda sprinkled on carpets or absorbent surfaces, or activated charcoal in open containers, can also help absorb lingering odors.
Can you get black mold out of clothes?
Yes, for black mold on clothes, start by taking them outside to brush off loose spores. Soak the garments in a solution of borax or white vinegar and water, then wash them in the hottest water safe for the fabric, adding more borax or vinegar. Dry thoroughly in direct sunlight if possible.
When should I call a professional for black mold removal?
You should call a professional for black mold removal if the mold covers an area larger than 10 square feet, if it's due to contaminated water (e.g., sewage), if you suspect mold behind walls or in HVAC systems, or if anyone in the household has severe mold-related health issues.
What causes black mold to grow in a home?
Black mold typically grows in areas with consistent moisture and organic material. Common causes include water leaks, high humidity, condensation, poor ventilation, and water damage from floods or plumbing issues. It thrives in damp, dark environments with a food source like drywall, wood, or fabric.
Is it safe to clean black mold yourself?
It can be safe to clean small, surface-level black mold infestations yourself, provided you wear appropriate personal protective equipment like an N95 mask, gloves, and goggles, and ensure proper ventilation. However, for large areas or if you have health concerns, professional help is strongly advised.
