Mold in the home is not only unpleasant to see but can also affect health by triggering allergies, respiratory discomfort, and skin irritation. It often develops on walls, ceilings, wooden surfaces, and even furniture—especially in areas with excess moisture or limited airflow. Removing mold quickly is essential to protect both your living space and overall well-being.
One of the most reliable and gentle methods for cleaning mold is using hydrogen peroxide. Unlike bleach, which mainly treats surface mold and can leave strong chemical residue, hydrogen peroxide penetrates deeper materials such as wood and drywall, helping to eliminate mold at its source. A 3% solution, which is commonly sold for household use, is safe and effective for this purpose.
To begin, gather what you’ll need: a spray bottle filled with 3% hydrogen peroxide, gloves, a mask, safety goggles, a scrub brush, clean cloths or sponges, and plastic coverings for nearby items. Prepare the area by removing or protecting surrounding objects and ensuring good ventilation. Spray hydrogen peroxide directly on the affected spots and let it sit for about 10 minutes so it can break down the mold.
Afterward, scrub the area with a brush and wipe it clean with cloths. If any mold remains, repeat the process until the surface is clear. Make sure the area dries completely—use fans, towels, or a dehumidifier to remove remaining moisture and prevent regrowth. To keep mold from coming back, fix any leaks, improve air circulation, keep humidity levels below 60%, and consider applying mold-resistant paint where needed. Always wear proper protective gear and never mix hydrogen peroxide with bleach or vinegar, as this may create unsafe fumes.
