Cleaning and Disinfecting

Cleaning and disinfecting are vital steps in the mold remediation process to ensure that mold growth is thoroughly addressed and does not return. When tackling mold, it’s important to recognize the difference between porous materials and hard surfaces. Porous materials—such as carpet, ceiling tiles, and drywall—can absorb moisture and harbor mold spores deep within, making them difficult or impossible to clean completely. In most cases, these materials should be removed and discarded to prevent further mold problems.

For hard surfaces like tile, glass, and metal, the Environmental Protection Agency recommends cleaning with a solution of 1 cup of bleach per 1 gallon of water. This mixture is effective at killing mold on non-porous surfaces; however, bleach is not recommended for porous materials because it cannot penetrate deeply and can release toxic fumes. Damp wiping is an effective method for cleaning hard non-porous and semi-porous surfaces, as it helps physically remove mold residues. It is also recommended to use a vacuum with a HEPA filter before and after cleaning to capture mold spores and prevent them from spreading. Be sure to apply the cleaning solution generously, scrub the surfaces thoroughly, and allow the area to air dry. Always wear gloves and ensure good ventilation when using bleach to protect your health, especially when dealing with hazardous decomp mold and related biohazards.

Remember, simply cleaning visible mold is not enough—removing contaminated materials and disinfecting all affected surfaces are key steps in the mold remediation process. By following these guidelines, you can help ensure that your mold problem is properly addressed and reduce the risk of future mold growth.
