Bleach is one of the best options to kill black mold on certain surfaces. It will not completely eliminate mold from some materials. Mold spores are everywhere in the environment and grow on most organic materials. Here is what you need to know.
Where Bleach Works
Bleach works on non-porous surfaces like tile, porcelain, acrylic and fiberglass tub-surrounds, and laminate countertops. Mold spores do not grow on non-porous surfaces. It grows on organic material like dirt, soap scum, wood, yard waste, etc. Mold requires moisture to grow so it is usually found in bathrooms, kitchens, attics, basements, and in the yard.
Bleach kills surface mold and cleans off the food source that hosts the spores. Mix one part bleach with ten parts water. Spray it on the mold or wipe it on with a sponge or cloth. Let the mixture soak in and work for about an hour. Wipe off the mold. Use a stiff bristle brush for difficult patches. Rinse the area well after cleaning. Dispose of your cleaning tools to ensure that all of the mold is gone.
Bleach fumes cause nausea, headache, and irritation to mucous membranes. It is poisonous if swallowed and can cause skin irritation. Handle with care and follow all instructions. Never mix bleach and ammonia. The fumes are toxic.
Where Bleach Doesn’t Work
Bleach does not kill black mold growing on porous surfaces like wood or drywall. Mold roots–also known as the membrane– spread deeply into porous surfaces. The chemical make-up of bleach prevents it from penetrating the membrane to kill the root. Mold roots will continue growing even if the surface mold is removed with bleach. Mold destroys drywall and starts rot in wood.
What To Use Instead Of Bleach
Some everyday and inexpensive products kill surface black mold and penetrate the membrane to kill the roots. Here are some options you can use instead of bleach.
- Vinegar. Spray the mold with undiluted white vinegar. Allow to sit for an hour. Wipe away the mold and let the surface air dry.
- Hydrogen Peroxide. Spray the infected area with undiluted 3% hydrogen peroxide. Let sit for about 15 minutes. Scrub off the mold with a sponge or stiff brush. Dry with a clean towel. Hydrogen peroxide helps to fade the black mold stain.
- Baking Soda. Mix one teaspoon of baking soda in two cups of water and spray on the moldy areas. Let sit for a few minutes. Then scrub off the mold. Baking soda is a natural deodorizer that helps eliminate mold odors.
- Essential Oils. Especially tea tree oil. Mix one tablespoon of oil into one cup of water. Spray on the mold and let sit for an hour. Wipe away the dead mold. Tea tree oil neutralizes the musky smell of mold.
- Lemon Juice. Squeeze the juice from three or four lemons and pour over the moldy areas. Allow the sit for at least five minutes. Wipe clean. Lemon scent improves the smell in the room.
