2. Why Choose Hydrogen Peroxide?
Hydrogen peroxide is a natural antifungal and antibacterial agent. At 3% concentration (the kind sold at most drugstores), it can penetrate porous surfaces like wood and drywall, killing mold at the root — something bleach can’t do. It’s also safer than bleach, breaking down into water and oxygen, with no toxic residue.
