How to Remove Mold from Your Home with Hydrogen Peroxide

Why It Matters
Mold often hides until it causes health issues like allergies or respiratory problems. It can also damage your home’s structure, so early removal is key.

Why Hydrogen Peroxide?
Unlike bleach, hydrogen peroxide penetrates porous surfaces like wood or drywall,

killing mold at the root without leaving toxic residue. A 3% solution, available at most stores, works best.

What You Need

3% hydrogen peroxide in a spray bottle

Gloves, mask, goggles

Scrub brush, cloths, sponges

Plastic sheets to cover nearby surfaces

Steps

Prepare the Area: Remove items, seal them in bags if needed, and ventilate the space.

Apply Solution: Spray hydrogen peroxide directly onto mold. Let sit at least 10 minutes.

Scrub and Wipe: Use a brush, then wipe clean. Repeat for stubborn spots.

Dry Completely: Use cloths, fans, or dehumidifiers. Moisture invites mold back.

Prevention
Fix leaks, improve ventilation, and keep humidity below 60%. Regularly check damp spaces and consider mold-resistant paint.

Safety & Mistakes to Avoid
Always wear protection. Don’t mix peroxide with bleach or vinegar. Let it sit long enough, and always address the source of moisture to prevent regrowth.
