According to CDC recommendations, “Mold can be removed from hard surfaces with household products, soap and water, or with a bleach solution of no more than 1 cup of household laundry bleach in 1 gallon of water. Bleach is effective and kills almost any type of indoor mold and spores. It leaves the surface clean, disinfected and resistant to future growth. However, it will only do so on non-porous materials such as tiles, countertops, glass and bathtubs.
Bleach cannot penetrate porous materials such as drywall, wood or textiles. If you use bleach on these materials, it only kills what's on the surface. And the mold will return soon. This is because only the chlorine in the bleach remains on the surface.
The water component of the bleach seeps into the material, providing more moisture for the mold to feed on. Hence a never-ending cycle of bleaching and bleaching. Bleach is also an aggressive chemical and can damage what you're cleaning. It emits strong vapors and can be harmful to the skin.
Therefore, when using bleach, always wear gloves and consider wearing a mask. Small areas of black mold growth detected at an early stage can be safely removed with disinfectant products. Use hydrogen peroxide, baking soda, cleaning vinegar, or bleach to kill and remove black mold. Since these ingredients can cause stains and discoloration on certain fabrics and materials, test the solution in an inconspicuous area before using it.
Some people recommend using household products such as Clorox wipes, laundry bleach, or vinegar to get rid of mold. Do they really work? They can do this if their mold problem is fairly mild. While these types of products can be effective in killing mold, they are effective only when the first signs of mold growth are recognized and its development is prevented.
